BMC Proc 2021 15 17 Acute encephalopathy syndrome (AES) is characterized by sudden onset of seizures and altered sensorium of infectious or non-infectious origin. Seasonal outbreaks of fatal hypoglycaemic AES in children, associated with eating fruit from the Sapindaceae family (e.g., ackee, litchi), have been reported globally [1,2]. Since 1995, AES outbreaks have been reported during the litchi-harvesting season from May–July in Muzaffarpur, the largest commercial litchi-producing district of Bihar, India [3]. An AES outbreak investigation in Muzaffarpur in 2014 linked known toxins hypoglycin A and α-methylene cyclopropyl glycine (MCPG) in litchi fruit to hypoglycaemic AES in children [3]. Following the 2014 outbreak, the Government of Bihar implemented community-based interventions to prevent hypoglycemia in children. They also strengthened the clinical management of hypoglycaemic seizures in public health facilities [4]. The number of AES cases and deaths declined from 2015–18, suggesting that the interventions were effective. However, in May–June 2019, AES cases increased. We conducted a descriptive epidemiological analysis of the AES cases. | | Methods | | We identified AES cases from established hospital-based surveillance in the two tertiary referral hospitals in Muzaffarpur. We defined a suspected AES case as seizures or altered sensorium in a child aged ≤15 years admitted from 1 May to 2nd July 2019. We excluded patients aged six months to 6 years who were admitted for fever and a single generalized convulsion of <15 minutes in duration and recovered consciousness within 60 minutes of seizure. We conducted a review of medical records and abstracted data using a structured tool for socio-demographics, clinical history, duration of hospitalization, treatment, and laboratory profile. We also assembled a prospective cohort of probable cases admitted to the hospital during the investigation. We defined a probable AES case as new-onset seizures or altered sensorium of <7 days duration in a child aged ≤15 years admitted t from 1 May to 2 July 2019. For the cohort of probable cases, we interviewed the caregivers using a structured clinical-epidemiological questionnaire for socio-demographics, anthropometry, illness characteristics, treatment-seeking behavior, meal assessment, exposure to litchi fruit, and exposure to health messages. For anthropometry, we calculated Z-scores using the World Health Organization 2006 standardized growth tables [5]. | | Results | | Of the 655 suspected and probable AES cases identified, the case fatality rate (CFR) was 21% (139 deaths). The median age was four years (interquartile range: 3 months–14 years), and 58% (378) were females. The first case was reported on 5 May 2019, cases peaked on 15 June, and the last case on 2 July (Figure 1). Among cases with available data, 75% (389/518) had blood glucose levels of <70 mg/dL upon hospital admission, and 75% (476/638) were residents of Muzaffarpur district. We identified cases from 15 (94%) of 16 blocks in the Muzaffarpur district and calculated a district incidence of 22 per 100,000 children ≤15 years old. | | The prospective cohort comprised 94 probable AES cases; CFR was 26%. Among probable cases, 63% (49/78) of caregivers were wage workers, and 34% (31/91) were of low socioeconomic status. Symptoms were reported in the early morning (3 am to 8 am) for 67% (62/93) of cases, and 97% (90/93) presented with seizures. Among probable cases with anthropometry data, 62% (43/69) were underweight (i.e., weight-for-age Z score <-2), 44% (25/57) stunted (i.e., height-for-age Z score <-2), and 43% (10/23) wasted (i.e., weight-for-height Z score <-2). Primary health facilities referred 46% (43/93) of probable cases to the two tertiary hospitals for admission. Among cases referred, only 30% (13/43) received hypoglycemia and seizure management at the primary health facility. | | Eating litchis in the 24 hours and seven days before illness onset was reported by 57% (54/94) and 87% (59/68) of caregivers, respectively. Skipping any meal and skipping the evening meal in the 24 hours before illness onset was reported by 55% (48/88) and 44% (28/63) of caregivers, respectively. Among probable cases, 45% (27/60) of caregivers reported Government Supplementary Nutrition (GSN) programme enrollment. Sixty percent (50/83) of caregivers said a visit by health workers in the week before illness. Still, only 8% (7/83) reported receiving messages on AES prevention and early treatment by health workers in the past month. | | Conclusions | | The 2019 AES outbreak in Muzaffarpur district, Bihar, occurred among young children with hypoglycemia upon hospital admission and had high associated mortality. Although the Government of Bihar implemented community and clinical measures to prevent AES cases after the 2014 outbreak, a large proportion of the AES cases did not benefit from the prevention measures based on our investigation [4]. New state and district health leadership, turnover of community and facility-level healthcare workers, lack of ongoing training and focused community outreach, and competing health priorities might have been factors responsible for the resurgence. To prevent future AES cases, we recommended prompt emergency management of hypoglycemia and seizures at primary health facilities before referral. We recommend enrollment of all eligible children to GSN and enhanced community health communications to reinforce the importance of an evening meal for children and limiting the eating of litchi fruit during the harvesting season from May to July |
Minority Health Social Vulnerability Index and COVID-19 vaccination coverage - The United States, December 14, 2020-January 31, 2022
Saelee R , Chandra Murthy N , Patel Murthy B , Zell E , Shaw L , Gibbs-Scharf L , Harris L , Shaw KM . Vaccine 2023 41 (12) 1943-1950 INTRODUCTION: In 2021, HHS Office of Minority Health and CDC developed a composite measure of social vulnerability called the Minority Health Social Vulnerability Index (MHSVI) to assess the needs of communities most vulnerable to COVID-19. The MHSVI extends the CDC Social Vulnerability Index with two new themes on healthcare access and medical vulnerability. This analysis examines COVID-19 vaccination coverage by social vulnerability using the MHSVI. METHODS: County-level COVID-19 vaccine administration data among persons aged ≥18 years reported to CDC from 12/14/20 to 01/31/22 were analyzed. U.S. counties from 50 states and DC were categorized into tertiles of vulnerability (low, moderate, and high) for the composite MHSVI measure and each of the 34 indicators. Vaccination coverage (≥1 dose, primary series completion, and receipt of a booster dose) was calculated by tertiles for the composite MHSVI measure and each indicator. RESULTS: Counties with lower per capita income, higher proportion of individuals with no high school diploma, living below poverty, ≥65 years of age, with a disability, and in mobile homes had lower vaccination uptake. However, counties with larger proportions of racial/ethnic minorities and individuals speaking English less than "very well" had higher coverage. Counties with fewer primary care physicians and greater medical vulnerabilities had lower ≥ 1 dose vaccination coverage. Furthermore, counties of high vulnerability had lower primary series completion and receipt of a booster dose. There were no clear patterns in COVID-19 vaccination coverage by tertiles for the composite measure. CONCLUSION: Results from the new components in the MHSVI identify needs to prioritize persons in counties with greater medical vulnerabilities and limited access to health care, who are at greater risk for adverse COVID-19 outcomes. Findings suggest that using a composite measure to characterize social vulnerability might mask disparities in COVID-19 vaccination uptake that would have otherwise been observed using specific indicators. |

Emerg Infect Dis 2022 28 (13) S138-s144 The India Field Epidemiology Training Program (FETP) has played a critical role in India's response to the ongoing COVID-19 pandemic. During March 2020-June 2021, a total of 123 FETP officers from across 3 training hubs were deployed in support of India's efforts to combat COVID-19. FETP officers have successfully mitigated the effect of COVID-19 on persons in India by conducting cluster outbreak investigations, performing surveillance system evaluations, and developing infection prevention and control tools and guidelines. This report discusses the successes of select COVID-19 pandemic response activities undertaken by current India FETP officers and proposes a pathway to augmenting India's pandemic preparedness and response efforts through expansion of this network and a strengthened frontline public health workforce. |
Risk factors for melioidosis in Udupi district, Karnataka, India, January 2017-July 2018

PLoS Glob Public Health 2022 2 (12) e0000865 We initiated an epidemiological investigation following the death of a previously healthy 17 year-old boy with neuro-melioidosis. A case was defined as a culture-confirmed melioidosis patient from Udupi district admitted to hospital A from January 2013-July 2018. For the case control study, we enrolled a subset of cases admitted to hospital A from January 2017- July 2018. A control was resident of Udupi district admitted to hospital A in July 2018 with a non-infectious condition. Using a matched case-control design, we compared each case to 3 controls using age and sex groups. We assessed for risk factors related to water storage, activities of daily living, injuries and environmental exposures (three months prior to hospitalization), using conditional regression analysis. We identified 50 cases with case fatality rate 16%. Uncontrolled diabetes mellitus was present in 84% cases and 66% of cases occurred between May and October (rainy season). Percutaneous inoculation through exposure to stagnant water and injury leading to breakage in the skin were identified as an important mode of transmission. We used these findings to develop a surveillance case definition and initiated training of the district laboratory for melioidosis diagnosis. |
Identifying deaths during and after pregnancy: New approaches to a perennial challenge
Trost SL , Beauregard J , Petersen EE , Cox S , Chandra G , St Pierre A , Rodriguez M , Goodman D . Public Health Rep 2022 138 (4) 333549221110487 Maternal mortality is increasingly recognized as a public health crisis in the United States, with growing attention on the 3 major systems of national surveillance. National maternal mortality statistics are reported by the Centers for Disease Control and Prevention’s (CDC’s) National Vital Statistics System (NVSS)1 within the National Center for Health Statistics (NCHS) and the Pregnancy Mortality Surveillance System (PMSS)2 within the Division of Reproductive Health (DRH). Comprehensive surveillance data at the state and local level are also available from maternal mortality review committees (MMRCs) via the Maternal Mortality Review Information Application (MMRIA).3 Each surveillance system has inherent strengths and limitations, but all rely on valid, accurate, and timely case identification via vital statistics data. We outline recent innovations to improve identification and ensure robust and accurate surveillance of maternal mortality in the United States. |

Hosp Pediatr 2022 12 (9) 760-783 OBJECTIVES: To describe COVID-19-related pediatric hospitalizations during a period of B.1.617.2 (Delta) variant predominance and to determine age-specific factors associated with severe illness. PATIENTS AND METHODS: We abstracted data from medical charts to conduct a cross-sectional study of patients aged <21 years hospitalized at 6 US children's hospitals during July-August 2021 for COVID-19 or with an incidental positive SARS-CoV-2 test. Among patients with COVID-19, we assessed factors associated with severe illness by calculating age-stratified prevalence ratios (PR). We defined severe illness as receiving high-flow nasal cannula, positive airway pressure, or invasive mechanical ventilation. RESULTS: Of 947 hospitalized patients, 759 (80.1%) had COVID-19, of whom 287 (37.8%) had severe illness. Factors associated with severe illness included coinfection with RSV (PR 3.64) and bacteria (PR 1.88) in infants; RSV coinfection in patients aged 1-4 years (PR 1.96); and obesity in patients aged 5-11 (PR 2.20) and 12-17 years (PR 2.48). Having ≥2 underlying medical conditions was associated with severe illness in patients aged <1 (PR 1.82), 5-11 (PR 3.72), and 12-17 years (PR 3.19). CONCLUSIONS: Among patients hospitalized for COVID-19, factors associated with severe illness included RSV coinfection in those aged <5 years, obesity in those aged 5-17 years, and other underlying conditions for all age groups <18 years. These findings can inform pediatric practice, risk communication, and prevention strategies, including vaccination against COVID-19. |

MMWR Morb Mortal Wkly Rep 2021 70 (5152) 1766-1772 During June 2021, the highly transmissible(†) B.1.617.2 (Delta) variant of SARS-CoV-2, the virus that causes COVID-19, became the predominant circulating strain in the United States. U.S. pediatric COVID-19-related hospitalizations increased during July-August 2021 following emergence of the Delta variant and peaked in September 2021.(§) As of May 12, 2021, CDC recommended COVID-19 vaccinations for persons aged ≥12 years,(¶) and on November 2, 2021, COVID-19 vaccinations were recommended for persons aged 5-11 years.** To date, clinical signs and symptoms, illness course, and factors contributing to hospitalizations during the period of Delta predominance have not been well described in pediatric patients. CDC partnered with six children's hospitals to review medical record data for patients aged <18 years with COVID-19-related hospitalizations during July-August 2021.(††) Among 915 patients identified, 713 (77.9%) were hospitalized for COVID-19 (acute COVID-19 as the primary or contributing reason for hospitalization), 177 (19.3%) had incidental positive SARS-CoV-2 test results (asymptomatic or mild infection unrelated to the reason for hospitalization), and 25 (2.7%) had multisystem inflammatory syndrome in children (MIS-C), a rare but serious inflammatory condition associated with COVID-19.(§§) Among the 713 patients hospitalized for COVID-19, 24.7% were aged <1 year, 17.1% were aged 1-4 years, 20.1% were aged 5-11 years, and 38.1% were aged 12-17 years. Approximately two thirds of patients (67.5%) had one or more underlying medical conditions, with obesity being the most common (32.4%); among patients aged 12-17 years, 61.4% had obesity. Among patients hospitalized for COVID-19, 15.8% had a viral coinfection(¶¶) (66.4% of whom had respiratory syncytial virus [RSV] infection). Approximately one third (33.9%) of patients aged <5 years hospitalized for COVID-19 had a viral coinfection. Among 272 vaccine-eligible (aged 12-17 years) patients hospitalized for COVID-19, one (0.4%) was fully vaccinated.*** Approximately one half (54.0%) of patients hospitalized for COVID-19 received oxygen support, 29.5% were admitted to the intensive care unit (ICU), and 1.5% died; of those requiring respiratory support, 14.5% required invasive mechanical ventilation (IMV). Among pediatric patients with COVID-19-related hospitalizations, many had severe illness and viral coinfections, and few vaccine-eligible patients hospitalized for COVID-19 were vaccinated, highlighting the importance of vaccination for those aged ≥5 years and other prevention strategies to protect children and adolescents from COVID-19, particularly those with underlying medical conditions. |
Chimeric Zika viruses containing structural protein genes of insect-specific flaviviruses cannot replicate in vertebrate cells due to entry and post-translational restrictions.
Tangudu CS , Charles J , Nunez-Avellaneda D , Hargett AM , Brault AC , Blitvich BJ . Virology 2021 559 30-39 Long Pine Key virus (LPKV) and Lammi virus are insect-specific flaviviruses that phylogenetically affiliate with dual-host flaviviruses. The goal of this study was to provide insight into the genetic determinants that condition this host range restriction. Chimeras were initially created by replacing select regions of the Zika virus genome, including the premembrane and envelope protein (prM-E) genes, with the corresponding regions of the LPKV genome. Of the four chimeras produced, one (the prM-E swap) yielded virus that replicated in mosquito cells. Another chimeric virus with a mosquito replication-competent phenotype was created by inserting the prM-E genes of Lammi virus into a Zika virus genetic background. Vertebrate cells did not support the replication of either chimeric virus although trace to modest amounts of viral antigen were produced, consistent with suboptimal viral entry. These data suggest that dual-host affiliated insect-specific flaviviruses cannot replicate in vertebrate cells due to entry and post-translational restrictions. |

Khan SU , Gurley ES , Gerloff N , Rahman MZ , Simpson N , Rahman M , Haider N , Chowdhury S , Balish A , Zaman RU , Nasreen S , Chandra Das B , Azziz-Baumgartner E , Sturm-Ramirez K , Davis CT , Donis RO , Luby SP . Sci Rep 2018 8 (1) 9396 Avian influenza viruses, including highly pathogenic strains, pose severe economic, animal and public health concerns. We implemented live bird market surveillance in Bangladesh to identify the subtypes of avian influenza A viruses in domestic waterfowl and market environments. We collected waterfowl samples monthly from 4 rural sites from 2007 to 2012 and environmental samples from 4 rural and 16 urban sites from 2009 to 2012. Samples were tested through real-time RT-PCR, virus culture, and sequencing to detect and characterize avian influenza A viruses. Among 4,308 waterfowl tested, 191 (4.4%) were positive for avian influenza A virus, including 74 (1.9%) avian influenza A/H5 subtype. The majority (99%, n = 73) of the influenza A/H5-positive samples were from healthy appearing waterfowl. Multiple subtypes, including H1N1, H1N3, H3N2, H3N6, H3N8, H4N1, H4N2, H4N6, H5N1 (clades 2.2.2, 2.3.2.1a, 2.3.4.2), H5N2, H6N1, H7N9, H9N2, H11N2 and H11N3, H11N6 were detected in waterfowl and environmental samples. Environmental samples tested positive for influenza A viruses throughout the year. Avian influenza viruses, including H5N1 and H9N2 subtypes were also identified in backyard and small-scale raised poultry. Live bird markets could be high-risk sites for harboring the viruses and have the potential to infect naive birds and humans exposed to them. |
Cost analysis of Prevention Research Centers: Instrument development
Rabarison KM , Marcelin RA , Bish CL , Chandra G , Massoudi MS , Greenlund KJ . J Public Health Manag Pract 2017 24 (5) 440-443 The 2014-2019 Prevention Research Centers (PRC) Program Funding Opportunity Announcement stated that "all applicants will be expected to collaborate with CDC to collect data to be able to perform cost analysis." For the first time in the 30-year history of the PRC Program, a cost indicator was included in the PRC Program Evaluation and a cost analysis (CA) instrument developed. The PRC-CA instrument systematically collects data on the cost of the PRC core research project to eventually answer the CDC PRC Program Evaluation question: "To what extent do investments in PRCs support the scalability, sustainability, and effectiveness of the outcomes resulting from community-engaged efforts to improve public health?" The objective of this article is to briefly describe the development of the PRC-CA instrument. Data obtained from the PRC-CA instrument can be used to generate cost summaries to inform decision making within the PRC Program and each individual PRC. |
Sustained progress, but no room for complacency: Results of 2015 HIV estimations in India

Indian J Med Res 2017 146 (1) 83-96 BACKGROUND & OBJECTIVES: Evidence-based planning has been the cornerstone of India's response to HIV/AIDS. Here we describe the process, method and tools used for generating the 2015 HIV estimates and provide a summary of the main results. METHODS: Spectrum software supported by the UNAIDS was used to produce HIV estimates for India as a whole and its States/Union Territories. This tool takes into consideration the size and HIV prevalence of defined population groups and programme data to estimate HIV prevalence, incidence and mortality over time as well as treatment needs. RESULTS: India's national adult prevalence of HIV was 0.26 per cent in 2015. Of the 2.1 million people living with HIV/AIDS, the largest numbers were in Andhra Pradesh, Maharashtra and Karnataka. New HIV infections were an estimated 86,000 in 2015, reflecting a decline by around 32 per cent from 2007. The declining trend in incidence was mirrored in most States, though an increasing trend was detected in Assam, Chandigarh, Chhattisgarh, Gujarat, Sikkim, Tripura and Uttar Pradesh. AIDS-related deaths were estimated to be 67,600 in 2015, reflecting a 54 per cent decline from 2007. There were variations in the rate and trend of decline across India for this indicator also. INTERPRETATION & CONCLUSIONS: While key indicators measured through Spectrum modelling confirm success of the National AIDS Control Programme, there is no room for complacency as rising incidence trends in some geographical areas and population pockets remain the cause of concern. Progress achieved so far in responding to HIV/AIDS needs to be sustained to end the HIV epidemic. |
Receipt of selected preventive health services for women and men of reproductive age - United States, 2011-2013
Pazol K , Robbins CL , Black LI , Ahrens KA , Daniels K , Chandra A , Vahratian A , Gavin LE . MMWR Surveill Summ 2017 66 (20) 1-31 PROBLEM/CONDITION: Receipt of key preventive health services among women and men of reproductive age (i.e., 15-44 years) can help them achieve their desired number and spacing of healthy children and improve their overall health. The 2014 publication Providing Quality Family Planning Services: Recommendations of CDC and the U.S. Office of Population Affairs (QFP) establishes standards for providing a core set of preventive services to promote these goals. These services include contraceptive care for persons seeking to prevent or delay pregnancy, pregnancy testing and counseling, basic infertility services for those seeking to achieve pregnancy, sexually transmitted disease (STD) services, and other preconception care and related preventive health services. QFP describes how to provide these services and recommends using family planning and other primary care visits to screen for and offer the full range of these services. This report presents baseline estimates of the use of these preventive services before the publication of QFP that can be used to monitor progress toward improving the quality of preventive care received by women and men of reproductive age. PERIOD COVERED: 2011-2013. DESCRIPTION OF THE SYSTEM: Three surveillance systems were used to document receipt of preventive health services among women and men of reproductive age as recommended in QFP. The National Survey of Family Growth (NSFG) collects data on factors that influence reproductive health in the United States since 1973, with a focus on fertility, sexual activity, contraceptive use, reproductive health care, family formation, child care, and related topics. NSFG uses a stratified, multistage probability sample to produce nationally representative estimates for the U.S. household population of women and men aged 15-44 years. This report uses data from the 2011-2013 NSFG. The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing, state- and population-based surveillance system designed to monitor selected maternal behaviors and experiences that occur before, during, and shortly after pregnancy among women who deliver live-born infants in the United States. Annual PRAMS data sets are created and used to produce statewide estimates of preconception and perinatal health behaviors and experiences. This report uses PRAMS data for 2011-2012 from 11 states (Hawaii, Maine, Maryland, Michigan, Minnesota, Nebraska, New Jersey, Tennessee, Utah, Vermont, and West Virginia). The National Health Interview Survey (NHIS) is a nationally representative survey of noninstitutionalized civilians in the United States. NHIS collects data on a broad range of health topics, including the prevalence, distribution, and effects of illness and disability and the services rendered for or because of such conditions. Households are identified through a multistage probability household sampling design, and estimates are produced using weights that account for the sampling design, nonresponse, and poststratification adjustments. This report uses data from the 2013 NHIS for women aged 18-44 years. RESULTS: Many preventive health services recommended in QFP were not received by all women and men of reproductive age. For contraceptive services, including contraceptive counseling and advice, 46.5% of women aged 15-44 years at risk for unintended pregnancy received services in the past year, and 4.5% of men who had vaginal intercourse in the past year received services in that year. For sexually transmitted disease (STD) services, among all women aged 15-24 years who had oral, anal, or vaginal sex with an opposite sex partner in the past year, 37.5% were tested for chlamydia in that year. Among persons aged 15-44 years who were at risk because they were not in a mutually monogamous relationship during the past year, 45.3% of women were tested for chlamydia and 32.5% of men were tested for any STD in that year. For preconception care and related preventive health services, data from selected states indicated that 33.2% of women with a recent live birth (i.e., 2-9 months postpartum) talked with a health care professional about improving their health before their most recent pregnancy; of selected preconception counseling topics, the most frequently discussed was taking vitamins with folic acid before pregnancy (81.2%), followed by achieving a healthy weight before pregnancy (62.9%) and how drinking alcohol (60.3%) or smoking (58.2%) during pregnancy can affect a baby. Nationally, among women aged 18-44 years irrespective of pregnancy status, 80.9% had their blood pressure checked by a health care professional and 31.7% received an influenza vaccine in the past year; 54.5% of those with high blood pressure were tested for diabetes, 44.9% of those with obesity had a health care professional talk with them about their diet, and 55.2% of those who were current smokers had a health professional talk with them about their smoking in the past year. Among all women aged 21-44 years, 81.6% received a Papanicolaou (Pap) test in the past 3 years. Receipt of certain preventive services varied by age and race/ethnicity. Among women with a recent live birth, the percentage of those who talked with a health care professional about improving their health before their most recent pregnancy increased with age (range: 25.9% and 25.2% for women aged ≤19 and 20-24 years, respectively, to 35.9% and 37.8% for women aged 25-34 and ≥35 years, respectively). Among women with a recent live birth, the percentage of those who talked with a health care professional about improving their health before their most recent pregnancy was higher for non-Hispanic white (white) (35.2%) compared with non-Hispanic black (black) (30.0%) and Hispanic (26.0%) women. Conversely, across most STD screening services evaluated, testing was highest among black women and men and lowest among their white counterparts. Receipt of many preventive services recommended in QFP increased consistently across categories of family income and continuity of health insurance coverage. Prevalence of service receipt was highest among women in the highest family income category (>400% of federal poverty level [FPL]) and among women with insurance coverage for each of the following: contraceptive services among women at risk for unintended pregnancy; medical services beyond advice to help achieve pregnancy; vaccinations (hepatitis B and human papillomavirus [HPV], ever; tetanus, past 10 years; influenza, past year); discussions with a health care professional about improving health before pregnancy and taking vitamins with folic acid; blood pressure and diabetes screening; discussions with a health care professional in the past year about diet, among those with obesity; discussions with a health care professional in the past year about smoking, among current smokers; Pap tests within the past 3 years; and mammograms within the past 2 years. INTERPRETATION: Before 2014, many women and men of reproductive age were not receiving several of the preventive services recommended for them in QFP. Although differences existed by age and race/ethnicity, across the range of recommended services, receipt was consistently lower among women and men with lower family income and greater instability in health insurance coverage. PUBLIC HEALTH ACTION: Information in this report on baseline receipt during 2011-2013 of preventive services for women and men of reproductive age can be used to target improvements in the use of recommended services through the development ofresearch priorities, information for decision makers, and public health practice. Health care administrators and practitioners can use the information to identify subpopulations with the greatest need for preventive services and make informed decisions on resource allocation. Public health researchers can use the information to guide research on the determinants of service use and factors that might increase use of preventive services.

J Perinatol 2017 37 (10) 1117-1123 OBJECTIVE: To evaluate the implementation of early screening for critical congenital heart defects (CCHDs) in the neonatal intensive care unit (NICU) and potential exclusion of sub-populations from universal screening. STUDY DESIGN: Prospective evaluation of CCHD screening at multiple time intervals was conducted in 21 NICUs across five states (n=4556 infants). RESULTS: Of the 4120 infants with complete screens, 92% did not have prenatal CHD diagnosis or echocardiography before screening, 72% were not receiving oxygen at 24 to 48 h and 56% were born 2500 g. Thirty-seven infants failed screening (0.9%); none with an unsuspected CCHD. False positive rates were low for infants not receiving oxygen (0.5%) and those screened after weaning (0.6%), yet higher among infants born at <28 weeks (3.8%). Unnecessary echocardiograms were minimal (0.2%). CONCLUSION: Given the majority of NICU infants were 2500 g, not on oxygen and not preidentified for CCHD, systematic screening at 24 to 48 h may be of benefit for early detection of CCHD with minimal burden.Journal of Perinatology advance online publication, 27 July 2017; doi:10.1038/jp.2017.105. |
Help and care seeking for sexually transmitted infections among youth in low- and middle-income countries
Newton-Levinson A , Leichliter JS , Chandra-Mouli V . Sex Transm Dis 2017 44 (6) 319-328 BACKGROUND: The ability to seek help or medical care for sexually transmitted infections (STIs) is vital for sexually active youth; yet, their needs are often unmet. METHODS: We conducted a qualitative systematic review of studies to assess youth and provider views about the behaviors of young people in help seeking and care seeking for STI services in low- and middle-income countries. We searched peer-reviewed literature for studies published between 2001 and 2014 with a study population of youth (age, 10–24 years) and/or health service providers. Eighteen studies were identified for inclusion from 18 countries. Thematic analyses identified key themes across the studies. RESULTS: The majority of studies included discussion of youth not seeking treatment, resorting to self-treatment, or waiting to access care, suggesting that many youth still do not seek timely care for STIs. Youth desired more information on sexual health and cited barriers related to fear or taboos in obtaining help or information, especially from providers or parents. Many did not recognize symptoms or waited until symptoms worsened. However, many youth were able to identify a number of sources for STI related care including public and private clinics, pharmacies, alternative healers, and nongovernmental organizations. Youthʼs help seeking and care seeking preferences were frequently influenced by desires for confidentiality, friendliness, and cost. CONCLUSIONS: Youth in low- and middle-income countries experience significant barriers in help seeking for STIs and often do not seek or postpone medical care. Improving uptake may require efforts to address clinic systems, provider attitudes, confidentiality, and cultural norms related to youth sexuality. |
Sexually transmitted infection services for adolescents and youth in low- and middle-income countries: Perceived and experienced barriers to accessing care
Newton-Levinson A , Leichliter JS , Chandra-Mouli V . J Adolesc Health 2016 59 (1) 7-16 PURPOSE: Access to sexual and reproductive health (SRH) services is vital for sexually active adolescents; yet, their SRH care needs are often unmet. METHODS: We conducted a qualitative systematic review of mixed methods studies to assess adolescent and provider views of barriers to seeking appropriate medical care for sexually transmitted infection (STI) services for adolescents. We searched peer-reviewed literature for studies published between 2001 and 2014 with a study population of youth (aged 10-24 years) and/or health service providers. Nineteen studies were identified for inclusion from 15 countries. Thematic analyses identified key themes across the studies. RESULTS: Findings suggest that youth lacked knowledge about STIs and services. In addition, youth experienced barriers related to service availability and a lack of integration of services. The most reported barriers were related to acceptability of services. Youth reported avoiding services or having confidentiality concerns based on provider demographics and some behaviors. Finally, experiences of shame and stigma were common barriers to seeking care. CONCLUSIONS: Adolescents in low- and middle-income countries experience significant barriers in obtaining STI and SRH services. Improving uptake may require efforts to address clinic systems and provider attitudes, including confidentiality issues. Moreover, addressing barriers to STI services may require addressing cultural norms related to adolescent sexuality. |
Supply of and demand for assisted reproductive technologies in the United States: clinic- and population-based data, 1995-2010
Stephen EH , Chandra A , King RB . Fertil Steril 2015 105 (2) 451-8 OBJECTIVE: To study national-level trends in assisted reproduction technology (ART) treatments and outcomes as well as the characteristics of women who have sought this form of infertility treatment. DESIGN: Population-based study. SETTING: Not applicable. PATIENT(S): For CDC: All reporting clinics from 1996-2010. For NSFG: for the logistic analysis, sample comprising 2,325 women aged 22-44 years who have ever used medical help to get pregnant, excluding women who used only miscarriage prevention services. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): CDC data (number of cycles, live birth deliveries, live births, patient diagnoses); and NSFG data (individual use of ART procedures). RESULT(S): Between 1995 and 2010, use of ART increased. Parity and age are strong predictors of using ART procedures. The other correlates are higher education, having had tubal surgery, and having a current fertility problem. CONCLUSION(S): The two complementary data sets highlight the trends of ART use. An increase in the use of ART services over this time period is seen in both data sources. Nulliparous women aged 35-39 years are the most likely to have ever used ART services. |
Modelling and estimation of HIV prevalence and number of people living with HIV in India, 2010-2011

Int J STD AIDS 2015 27 (14) 1257-1266 This paper provides HIV estimation methodology used in India and key HIV estimates for 2010-2011. We used a modified version of the Spectrum tool that included Estimation and Projection Package as part of its AIDS Impact Module. Inputs related to population size, age-specific pattern of fertility, sex-ratio at birth, age and sex-specific pattern of mortality, and volume and age-sex distribution of net migration were derived from census records, Sample Registration System and large-scale demographic health surveys. Epidemiological and programmatic data were derived from HIV sentinel surveillance, large-scale epidemiological surveys and the programme management information system. Estimated adult HIV prevalence retained a declining trend in India, following its peak in 2002 at a level of 0.41% (within bounds 0.35-0.47%). By 2010 and 2011, it levelled at estimates of 0.28% (0.24-0.34%) and 0.27% (0.22-0.33%), respectively. The estimated number of people living with HIV (PLHIV) reduced by 8% between 2007 and 2011. While children accounted for approximately 6.3% of total HIV infections in 2007, this proportion increased to about 7% in 2011. With changing priorities and epidemic patterns, the programme has to customise its strategies to effectively address the emerging vulnerabilities and adapt them to suit the requirements of different geographical regions. |
Epidemiologic Investigation of a Cluster of Neuroinvasive Bacillus cereus Infections in 5 Patients With Acute Myelogenous Leukemia.

Open Forum Infect Dis 2015 2 (3) ofv096 BACKGROUND: Five neuroinvasive Bacillus cereus infections (4 fatal) occurred in hospitalized patients with acute myelogenous leukemia (AML) during a 9-month period, prompting an investigation by infection control and public health officials. METHODS: Medical records of case-patients were reviewed and a matched case-control study was performed. Infection control practices were observed. Multiple environmental, food, and medication samples common to AML patients were cultured. Multilocus sequence typing was performed for case and environmental B cereus isolates. RESULTS: All 5 case-patients received chemotherapy and had early-onset neutropenic fevers that resolved with empiric antibiotics. Fever recurred at a median of 17 days (range, 9-20) with headaches and abrupt neurological deterioration. Case-patients had B cereus identified in central nervous system (CNS) samples by (1) polymerase chain reaction or culture or (2) bacilli seen on CNS pathology stains with high-grade B cereus bacteremia. Two case-patients also had colonic ulcers with abundant bacilli on autopsy. No infection control breaches were observed. On case-control analysis, bananas were the only significant exposure shared by all 5 case-patients (odds ratio, 9.3; P = .04). Five environmental or food isolates tested positive for B cereus, including a homogenized banana peel isolate and the shelf of a kitchen cart where bananas were stored. Multilocus sequence typing confirmed that all case and environmental strains were genetically distinct. Multilocus sequence typing-based phylogenetic analysis revealed that the organisms clustered in 2 separate clades. CONCLUSIONS: The investigation of this neuroinvasive B cereus cluster did not identify a single point source but was suggestive of a possible dietary exposure. Our experience underscores the potential virulence of B cereus in immunocompromised hosts. |

Genome Res 2014 24 (10) 1676-85 Global production of chickens has trebled in the past two decades and they are now the most important source of dietary animal protein worldwide. Chickens are subject to many infectious diseases that reduce their performance and productivity. Coccidiosis, caused by apicomplexan protozoa of the genus Eimeria, is one of the most important poultry diseases. Understanding the biology of Eimeria parasites underpins development of new drugs and vaccines needed to improve global food security. We have produced annotated genome sequences of all seven species of Eimeria that infect domestic chickens, which reveal the full extent of previously described repeat-rich and repeat-poor regions and show that these parasites possess the most repeat-rich proteomes ever described. Furthermore, while no other apicomplexan has been found to possess retrotransposons, Eimeria is home to a family of chromoviruses. Analysis of Eimeria genes involved in basic biology and host-parasite interaction highlights adaptations to a relatively simple developmental life cycle and a complex array of co-expressed surface proteins involved in host cell binding. |
Characterization of Cannabis sativa allergens
Nayak AP , Green BJ , Sussman G , Berlin N , Lata H , Chandra S , Elsohly MA , Hettick JM , Beezhold DH . Ann Allergy Asthma Immunol 2013 111 (1) 32-37 e4 BACKGROUND: Allergic sensitization to Cannabis sativa is rarely reported, but the increasing consumption of marijuana has resulted in an increase in the number of individuals who become sensitized. To date, little is known about the causal allergens associated with C sativa. OBJECTIVE: To characterize marijuana allergens in different components of the C sativa plant using serum IgE from marijuana sensitized patients. METHODS: Serum samples from 23 patients with a positive skin prick test result to a crude C sativa extract were evaluated. IgE reactivity was variable between patients and C sativa extracts. IgE reactivity to C sativa proteins in Western blots was heterogeneous and ranged from 10 to 70 kDa. Putative allergens derived from 2-dimensional gels were identified. RESULTS: Prominent IgE reactive bands included a 23-kDa oxygen-evolving enhancer protein 2 and a 50-kDa protein identified to be the photosynthetic enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase. Additional proteins were identified in the proteomic analysis, including those from adenosine triphosphate synthase, glyceraldehyde-3-phosphate dehydrogenase, phosphoglycerate kinase, and luminal binding protein (heat shock protein 70), suggesting these proteins are potential allergens. Deglycosylation studies helped refine protein allergen identification and demonstrated significant IgE antibodies against plant oligosaccharides that could help explain cross-reactivity. CONCLUSION: Identification and characterization of allergens from C sativa may be helpful in further understanding allergic sensitization to this plant species. |
Correlates of self-reported pelvic inflammatory disease treatment in sexually experienced reproductive-aged women in the United States, 1995 and 2006-2010
Leichliter JS , Chandra A , Aral SO . Sex Transm Dis 2013 40 (5) 413-8 BACKGROUND: Few studies have examined recent temporal trends in self-reported receipt of pelvic inflammatory disease (PID) treatment. We assessed trends in receipt of PID treatment and associated correlates using national survey data. METHODS: We used data from the National Survey of Family Growth, a multistage national probability survey of 15- to 44-year-old women. We examined trends in self-reported receipt of PID treatment from 1995, 2002, to 2006-2010. In addition, we examined correlates of PID treatment in 1995 and 2006-2010 in bivariate and adjusted analyses. RESULTS: From 1995 to 2002, receipt of PID treatment significantly declined from 8.6% to 5.7% (P < 0.0001); however, there was no difference from 2002 to 2006-2010 (5.0%, P = 0.16). In bivariate analyses, racial differences in PID treatment declined across time; in 2006-2010, there was no significant difference between racial/ethnic groups (P = 0.22). Also in bivariate analyses, similar to 1995, in 2006 to 2010, some of the highest reports of receipt of PID treatment were women who were 35 to 44 years old (5.6%), had an income less than 150% of poverty level (7.5%), had less than high school education (6.7%), douched (7.7%), had intercourse before age 15 years (10.3%), and had 10 or more lifetime partners (8.0%). In adjusted analyses, differing from 1995, women at less than 150% of the poverty level were more likely (adjusted odds ratio [AOR], 2.60; 95% confidence interval [CI], 1.79-3.76) than women at 300% or more of the poverty level to have received PID treatment in 2006-2010. CONCLUSIONS: Receipt of PID treatment declined from 1995 to 2006-2010, with the burden affecting women of lower socioeconomic status. |
HIV risk-related behaviors in the United States household population aged 15-44 years: data from the National Survey of Family Growth, 2002 and 2006-2010
Chandra A , Billioux VG , Copen CE , Sionean C . Natl Health Stat Report 2012 (46) 1-19 OBJECTIVE: This report presents national estimates of selected HIV risk-related behaviors among men and women 15-44 years of age in the United States, based on the 2006-2010 National Survey of Family Growth (NSFG). Data from the 2006-2010 NSFG are compared with data from the 2002 NSFG. METHODS: Data for 2006-2010 were collected through in-person interviews with a national sample of 22,682 men and women aged 15-44 years in the household population of the United States. The measures presented in this report were collected using audio computer-assisted self-interviewing (ACASI), in which the respondent enters his or her own answers into the computer without telling them to an interviewer. The response rate for the 2006-2010 NSFG was 77%, 78% for women and 75% for men. HIV risk-related behavioral measures examined in this report include sexual risk, drug risk, and recent STD treatment. REPORTS: Approximately 10% of men and 8% of women in 2006-2010 reported at least one of the HIV risk-related behavioral measures examined in this report, representing 6.5 million men and 4.9 million women in the general U.S. household population. This represents a decline from the 13% of men and 11% of women who reported one or more of these measures in 2002. This decline appears to be due to a decrease in sexual risk behaviors reported in 2006-2010, however further analysis as well as comparisons with other household surveys are needed to fully understand and describe trends over time. Significant variations were seen by demographic and socioeconomic characteristics including age, race and Hispanic origin, sex, education, and poverty level income. Among men, those with recent prison experience were more likely than other men to report one or more HIV risk-related behaviors in the past year. |
Sexual behavior, sexual attraction, and sexual identity in the United States: data from the 2006-2008 National Survey of Family Growth
Chandra A , Mosher WD , Copen C , Sionean C . Natl Health Stat Report 2011 (36) 1-36 OBJECTIVE: This report presents national estimates of several measures of sexual behavior, sexual attraction, and sexual identity among males and females aged 15-44 years in the United States, based on the 2006-2008 National Survey of Family Growth (NSFG). These data are relevant to demographic and public health concerns, including fertility and sexually transmitted infections among teenagers and adults. Data from the 2006-2008 NSFG are compared with data from the 2002 NSFG and other national surveys. METHODS: Data for 2006-2008 were collected through in-person interviews with a national sample of 13,495 males and females in the household population of the United States. The measures presented in this report were collected using audio computer-assisted self interviewing (ACASI), in which the respondent enters his or her own answers into the computer without telling them to an interviewer. The overall response rate for the 2006-2008 NSFG was 75%. RESULTS: Sexual behaviors among males and females aged 15-44 based on the 2006-2008 NSFG were generally similar to those reported based on the 2002 NSFG. Among adults aged 25-44, about 98% of women and 97% of men ever had vaginal intercourse, 89% of women and 90% of men ever had oral sex with an opposite-sex partner, and 36% of women and 44% of men ever had anal sex with an opposite-sex partner. Twice as many women aged 25-44 (12%) reported any same-sex contact in their lifetimes compared with men (5.8%). Among teenagers aged 15-19, 7% of females and 9% of males have had oral sex with an opposite-sex partner, but no vaginal intercourse. Sexual attraction and identity correlates closely but not completely with reports of sexual behavior. Sexual behaviors, attraction, and identity vary by age, marital or cohabiting status, education, and race and Hispanic origin. |

Circulation 2011 123 (11) 1243-62 Substantial progress has been made in the awareness, treatment, and prevention of cardiovascular disease (CVD) in women since the first women-specific clinical recommendations for the prevention of CVD were published by the American Heart Association (AHA) in 1999.1 The myth that heart disease is a “man’s disease” has been debunked; the rate of public awareness of CVD as the leading cause of death among US women has increased from 30% in 1997 to 54% in 2009.2 The age-adjusted death rate resulting from coronary heart disease (CHD) in females, which accounts for about half of all CVD deaths in women, was 95.7 per 100 000 females in 2007, a third of what it was in 1980.3,4 Approximately 50% of this decline in CHD deaths has been attributed to reducing major risk factors and the other half to treatment of CHD including secondary preventive therapies.4 Major randomized controlled clinical trials such as the Women’s Health Initiative have changed the practice of CVD prevention in women over the past decade.5 The investment in combating this major public health issue for women has been significant, as have the scientific and medical achievements. | Despite the gains that have been made, considerable challenges remain. In 2007, CVD still caused ≈1 death per minute among women in the United States.6 These represent 421 918 deaths, more women’s lives than were claimed by cancer, chronic lower respiratory disease, Alzheimer disease, and accidents combined.6 Reversing a trend of the past 4 decades, CHD death rates in US women 35 to 54 years of age now actually appear to be increasing, likely because of the effects of the obesity epidemic.4 CVD rates in the United States are significantly higher for black females compared with their white counterparts (286.1/100 000 versus 205.7/100 000). This disparity parallels the substantially lower rate of awareness of heart disease and stroke that has been documented among black versus white women.2,6–8 Of concern is that in a recent AHA national survey, only 53% of women said the first thing they would do if they thought they were having a heart attack was to call 9-1-1. This distressing lack of appreciation by many women for the need for emergency care for acute cardiovascular events is a barrier to optimal survival among women and underscores the need for educational campaigns targeted to women.2 |
Developing national standards for public health emergency preparedness with a limited evidence base
Nelson C , Chan E , Chandra A , Sorensen P , Willis HH , Dulin S , Leuschner K . Disaster Med Public Health Prep 2010 4 (4) 285-90 OBJECTIVE: The paucity of evidence and wide variation among communities creates challenges for developing congressionally mandated national performance standards for public health preparedness. Using countermeasure dispensing as an example, we present an approach for developing standards that balances national uniformity and local flexibility, consistent with the quality of evidence available. METHODS: We used multiple methods, including a survey of community practices, mathematical modeling, and expert panel discussion.RESULTS: The article presents recommended dispensing standards, along with a general framework that can be used to analyze tradeoffs involved in developing other preparedness standards. CONCLUSIONS: Standards can be developed using existing evidence, but would be helped immensely by a stronger evidence base. |
Infertility service use among U.S. women: 1995 and 2002
Chandra A , Stephen EH . Fertil Steril 2010 93 (3) 725-36 OBJECTIVE: To examine trends in use of medical services for infertility, by individual characteristics of women. DESIGN: Pooled data from two cycles (1995 and 2002) of the National Survey of Family Growth, a periodically conducted, nationally representative, cross-sectional survey of women 15-44 years of age. PARTICIPANT(S): The analysis sample was composed of 2,005 women 22-44 years of age with current fertility problems. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Ever having used infertility services, and highest level of services used. RESULT(S): Between 1995 and 2002, ever-use of infertility services by fertility-impaired women age 22-44 years continued to be closely associated with older age, nulliparity, formal marital status, and higher socioeconomic status (education, household income, and private health insurance). Net of these factors, race and Hispanic origin, showed no significant association with either the use of services overall or the highest level of services used. After controlling for compositional changes in these individual characteristics, a slight decline was seen in ever-use of services overall from 1995 to 2002. No effect of survey year was noted in the highest level of services. CONCLUSION(S): Infertility service use among fertility-impaired women remains closely tied with socioeconomic factors. The "threshold effect" of these factors has shifted upward to the receipt of more costly services such as assisted reproductive technologies. These higher level services remain a relatively small fraction of the services reported in a general population sample of fertility-impaired women. |
A public health focus on infertility prevention, detection, and management
Macaluso M , Wright-Schnapp TJ , Chandra A , Johnson R , Satterwhite CL , Pulver A , Berman SM , Wang RY , Farr SL , Pollack LA . Fertil Steril 2010 93 (1) 16 e1-10 In 2002, 2 million American women of reproductive age were infertile. Infertility is also common among men. The Centers for Disease Control and Prevention (CDC) conducts surveillance and research on the causes of infertility, monitors the safety and efficacy of infertility treatment, and sponsors national prevention programs. A CDC-wide working group found that, despite this effort, considerable gaps and opportunities exist in surveillance, research, communication, and program and policy development. We intend to consult with other federal agencies, professional and consumer organizations, the scientific community, the health care community, industry, and other stakeholders, and participate in the development of a national public health plan for the prevention, detection, and management of infertility. |
Comparison of national malaria surveillance system with the national notifiable diseases surveillance system in the United States
Hwang J , McClintock S , Kachur SP , Slutsker L , Arguin P . J Public Health Manag Pract 2009 15 (4) 345-51 BACKGROUND: The Centers for Disease Control and Prevention (CDC) is in the process of integrating the existing dual mechanisms for reporting cases of malaria diagnosed in the United States into a single electronic reporting mechanism. Before adoption of this new system, an evaluation of the existing systems for state-level reporting of malaria data to the CDC was conducted. METHODS: CDC guidelines for evaluating surveillance systems were used to assess the attributes of the National Malaria Surveillance System (NMSS), the current National Notifiable Diseases Surveillance System (NNDSS), and the projected fully integrated NNDSS. We analyzed data collected from NMSS and NNDSS from 2001 to 2005 using the Chandra-Sekar-Deming method to estimate completeness of reporting. RESULTS: The projected fully integrated system was assessed likely to perform better than either of the existing systems on all attributes except stability. The overall completeness of reporting was estimated to be 80.3 percent for NNDSS and 74.7 percent for NMSS. CONCLUSIONS: Both existing systems have reasonably high ascertainment of cases. A fully integrated system with malaria-specific data fields would improve upon existing systems if it proved to be stable. |
