Reaching youth through faith leaders: Evaluation of the Faith Matters! Initiative
Kanagasabai U , Aholou T , Chevalier MS , Tobias JL , Okuku J , Shiraishi RW , Sheneberger R , Pande YC , Chifuwe C , Mamane LE , Njika G , Obongo C , Thorsen VC . AIDS Educ Prev 2023 35 82-99 Faith leaders can be uniquely positioned to guide and support young people on health issues, particularly HIV/AIDS and sexual violence. Faith Matters!, a 2-day training workshop for faith leaders, was delivered in September 2021 in Zambia. Sixty-six faith leaders completed a questionnaire at baseline, 64 at posttraining, and 59 at 3-month follow-up. Participants' knowledge, beliefs, and comfort communicating about HIV/AIDS and sexual violence were assessed. More faith leaders accurately identified common places where sexual violence occurs at the 3-month point compared to baseline: at church (2 vs. 22, p = .000), the fields (16 vs. 29, p = .004), parties (22 vs. 36, p = .001), and clubs (24 vs. 35, p = .034). More faith leaders stated that they engaged in conversations that supported people living with HIV (48 at baseline vs. 53, p = .049 at 3-month follow-up). These findings can inform future HIV/AIDS initiatives focusing on increasing the capacity among communities of faith. |
Understanding gender-based violence service delivery in CDC-supported health facilities: 15 Sub-Saharan African Countries, 2017-2021
Kanagasabai U , Valleau C , Cain M , Chevalier MS , Hegle J , Patel P , Benevides R , Trika JB , Angumua C , Mpingulu M , Ferdinand K , Sida F , Galloway K , Kambona C , Oluoch P , Msungama W , Katengeza H , Correia D , Duffy M , Cossa RMV , Coomer R , Ayo A , Ukanwa C , Tuyishime E , Dladla S , Drummond J , Magesa D , Kitalile J , Apondi R , Okuku J , Chisenga T , Cham HJ . AIDS Educ Prev 2023 35 39-51 Gender-based violence (GBV) is a complex issue deeply rooted in social structures, making its eradication challenging. GBV increases the risk of HIV transmission and is a barrier to HIV testing, care, and treatment. Quality clinical services for GBV, which includes the provision of HIV postexposure prophylaxis (PEP), vary, and service delivery data are lacking. We describe GBV clinical service delivery in 15 countries supported by the President's Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Centers for Disease Control and Prevention. Through a descriptive statistical analysis of PEPFAR Monitoring, Evaluation, and Reporting (MER) data, we found a 252% increase in individuals receiving GBV clinical services, from 158,691 in 2017 to 558,251 in 2021. PEP completion was lowest (15%) among 15-19-year-olds. Understanding GBV service delivery is important for policy makers, program managers, and providers to guide interventions to improve the quality of service delivery and contribute to HIV epidemic control. |
Preexposure prophylaxis among pregnant and lactating people in 18 PEPFAR-supported countries: a review of HIV strategies and guidelines
Abadan SS , Hawryluk L , Montandon M , Flowers N , Schueller J , Eakle R , Patel P , Chevalier MS , Rana S , Amzel A . Glob Health Sci Pract 2022 10 (6) Introduction: Pregnant and lactating people (PLP) experience heightened risk of acquiring HIV, which adversely impacts their health and increases the risk for vertical HIV transmission. Preexposure prophylaxis (PrEP), as part of a combination prevention package, including condoms, sexually transmitted infection prevention, and regular HIV testing, is a safe, efficacious method to prevent HIV infections among PLP and their infants. This article examines the evolution of strategies and guidance on PrEP services for PLP from 18 countries supported by the U.S. President's Emergency Plan for AIDS Relief (PEPFAR). |
Real-Time CDC Consultation during the COVID-19 Pandemic-United States, March-July, 2020.
Wozniczka D , Demeke HB , Thompson-Paul AM , Ijeoma U , Williams TR , Taylor AW , Tan KR , Chevalier MS , Agyemang E , Dowell D , Oduyebo T , Shiferaw M , Coleman King SM , Minta AA , Shealy K , Oliver SE , McLean C , Glover M , Iskander J . Int J Environ Res Public Health 2021 18 (14) Context: In response to the COVID-19 pandemic, the Centers for Disease Prevention and Control (CDC) clinicians provided real-time telephone consultation to healthcare providers, public health practitioners, and health department personnel. Objective: To describe the demographic and public health characteristics of inquiries, trends, and correlation of inquiries with national COVID-19 case reports. We summarize the results of real-time CDC clinician consultation service provided during 11 March to 31 July 2020 to understand the impact and utility of this service by CDC for the COVID-19 pandemic emergency response and for future outbreak responses. Design: Clinicians documented inquiries received including information about the call source, population for which guidance was sought, and a detailed description of the inquiry and resolution. Descriptive analyses were conducted, with a focus on characteristics of callers as well as public health and clinical content of inquiries. Setting: Real-time telephone consultations with CDC Clinicians in Atlanta, GA. Partic-ipants: Health care providers and public health professionals who called CDC with COVID-19 related inquiries from throughout the United States. Main Outcome Measures: Characteristics of inquiries including topic of inquiry, inquiry population, resolution, and demographic information. Results: A total of 3154 COVID-19 related telephone inquiries were answered in real-time. More than half (62.0%) of inquiries came from frontline healthcare providers and clinical sites, followed by 14.1% from state and local health departments. The majority of inquiries focused on issues in-volving healthcare workers (27.7%) and interpretation or application of CDC’s COVID-19 guidance (44%). Conclusion: The COVID-19 pandemic resulted in a substantial number of inquiries to CDC, with the large majority originating from the frontline clinical and public health workforce. Analysis of inquiries suggests that the ongoing focus on refining COVID-19 guidance documents is war-ranted, which facilitates bidirectional feedback between the public, medical professionals, and public health authorities. © 2021 by the authors.

Evaluation of the WHO global database on blood safety
Kanagasabai U , Selenic D , Chevalier MS , Drammeh B , Qualls M , Shiraishi RW , Bock N , Benech I , Mili FD . Vox Sang 2020 116 (2) 197-206 OBJECTIVE: While the Global Database on Blood Safety (GDBS) helps to monitor the status of adequate and safe blood availability, its presence alone does not serve as a solution to existing challenges. The objective of this evaluation was to determine the GDBS usefulness in improving the availability of adequate safe blood and its ability to function as a surveillance system. METHODS: The GDBS was evaluated using methods set out by the Centers for Disease Control and Prevention (CDC) Guidelines for assessing surveillance systems. Six recommended tasks were used to evaluate if the GDBS met the requirements of a surveillance system in a public health context. RESULTS: The majority of stakeholders engaged with GDBS found it was unique and useful. The GDBS answered all six questions essential for determining a blood safety surveillance system's usefulness. The GDBS fully met the needs to six of the eleven attributes used for evaluating the usefulness of a surveillance system. CONCLUSION: The GDBS is a unique global activity that provides vital data on safety of blood transfusion services across countries and regions. However, aspects of the GDBS such as timeliness of reporting and improvement of WHO Member States national blood information systems could enhance its effectiveness and potential to serve as a global surveillance system for blood safety. |
Trends in hepatitis B and hepatitis C seroprevalence among blood donors - Haiti, 2005-2014
Baptiste AEJ , Chevalier MS , Polo E , Noel E , Hulland EN , Archer WR . ISBT Sci Ser 2018 13 (2) 150-157 Background and Objectives: Data on the seroprevalence of viral hepatitis are limited in Haiti; consequently, the epidemiology is poorly described. This study aims to provide a descriptive analysis of hepatitis B virus (HBV) and hepatitis C virus (HCV) seroprevalence of blood donations in Haiti. Materials and Methods: Using Haiti's National Blood Safety Program and Haitian Red Cross reports from 2005 to 2014, we analysed the results of screening tests of donor serum samples to assess HBV and HCV seroprevalence among adults aged 17 to 65 years. Results: A total of 198 758 donor samples were screened from 2005 to 2014, of which 0.56% were positive for antibody to hepatitis C virus (anti-HCV) and 3.80% were positive for hepatitis B surface antigen. Over the 10-year study period, anti-HCV seroprevalence among blood donors increased by 31% from 0.66% to 0.86% (95% CI: 1.01-1.70); however, this trend was not uniform over time, with a significant decrease from 0.66% in 2005 to 0.39% in 2009 (95% CI: 0.43- 0.82) and 0.43% in 2012 (95% CI: 0.50-0.90). Conversely, HBV decreased significantly by 13% from 3.95% in 2005 to 3.42% in 2014 (95% CI: 0.77-0.97), a trend that was also observed in 2012 and 2013. Conclusion: The significant, uniform decrease in HBV seroprevalence in more recent years may represent the positive impact of public health interventions in preventing the transmission of blood-borne infections. More research is needed to understand why the trends in HCV transmission are non-uniform and to investigate the significant increase in more recent years. |
Trends and gaps in national blood transfusion services - 14 sub-Saharan African countries, 2014-2016
Kanagasabai U , Chevalier MS , Drammeh B , Mili FD , Qualls ML , Bock N , Benech I , Nelson LJ , Alemnji G , Watts DH , Kimani D , Selenic D . MMWR Morb Mortal Wkly Rep 2018 67 (50) 1392-1396 Ensuring availability of safe blood products through recruitment of voluntary, nonremunerated, blood donors (VNRDs) and prevention of transfusion-transmissible infections (TTIs), including human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis, is important for public health (1,2). During 2004-2016, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) provided approximately $468 million in financial support and technical assistance* to 14 sub-Saharan African countries(dagger) with high HIV prevalence to strengthen national blood transfusion services (NBTSs)( section sign) and improve blood safety and availability. CDC analyzed these countries' 2014-2016 blood safety surveillance data to update previous reports (1,2) and summarize achievements and programmatic gaps as some NBTSs begin to transition funding and technical support from PEPFAR to local ministries of health (MOHs) (2,3). Despite a 60% increase in blood supply since 2004 and steady declines in HIV prevalence (to <1% among blood donors in seven of the 14 countries), HIV prevalence among blood donors still remains higher than that recommended by the World Health Organization (WHO) (4). PEPFAR support has contributed to significant reductions in HIV prevalence among blood donors in the majority of PEPFAR-supported countries, and linking donors who screen HIV-positive to confirmatory testing and indicated treatment, as well as further reducing TTIs, remains a public health priority (5). |
Availability and use of contraceptive implants in Jamaica: Results of a review of medical records and a survey of reproductive healthcare providers in six public health centres
Chevalier MS , King CC , Jarrett S , Sutherland S , Hill SM , Kourtis AP . West Indian Med J 2018 67 (2) 114-121 Objective: The prevalence of sub-dermal contraceptive implant use in Jamaica is low, despite growing international acceptance of long-acting reversible contraception. This study assessed the availability, effectiveness, side-effects and utilization of sub-dermal contraceptive implants and described the characteristics of users over a one-year period. Methods: We reviewed the medical records of women aged 15-45 years who utilized contraceptive implant-related services at any of the six included public health centres in Jamaica during 2013, and surveyed 20 available reproductive healthcare providers. Results: In 2013, 738 women attended a Jamaican public health centre for contraceptive implant services: 493 (66.8%) for insertion, 202 (27.4%) for removal and 53 (7.2%) for follow- up visits (10 women had the same implant inserted and removed in 2013). The women's median age was 26.0 years, 24.3% were <= 18 years, and 85.9% had >= 1 child. Most women (68.5%) did not have documented side-effects; irregular bleeding, the most commonly documented side-effect, was recorded for 24%. Of the 493 women who had implants inserted, three (0.6%) were identified to be pregnant within three months of insertion. Among the 202 women who had implants removed, 11 (5.4%) experienced complications with removal. Reproductive healthcare providers highlighted the need for an expansion of contraceptive implant availability and provider training. Conclusion: Sub-dermal implants have few insertion complications and side-effects and are effective, but were underutilized in Jamaica. Increased implant availability and enhanced reproductive healthcare provider training may improve implant utilization and reduce unintended pregnancy rates in Jamaica. |
Use of blood donor screening data to estimate Zika virus incidence, Puerto Rico, April-August 2016
Chevalier MS , Biggerstaff BJ , Basavaraju SV , Banez Ocfemia MC , Alsina JO , Climent-Peris C , Moseley RR , Chung KW , Rivera-Garcia B , Bello-Pagan M , Pate LL , Galel SA , Williamson P , Kuehnert MJ . Emerg Infect Dis 2017 23 (5) 790-795 Puerto Rico has been heavily impacted by Zika virus, a mosquitoborne flavivirus that emerged in the Americas during 2015. Although most persons with Zika virus show no symptoms, the virus can cause neurologic and other complications, including fetal microcephaly. Local Zika virus transmission in Puerto Rico has been reported since December 2015. To prevent transfusion-associated transmission, local blood collection ceased in March 2016 but resumed in April 2016 after Zika virus screening of blood donations became available. Using data from screening of blood donations collected by the 2 largest blood centers in Puerto Rico during April 3-August 12, 2016, and assuming a 9.9-day duration of viremia, we estimated that 469,321 persons in Puerto Rico were infected during this period, for an estimated cumulative incidence of 12.9%. Results from blood donation screening during arboviral outbreaks can supplement routine clinical and surveillance data for improved targeting of prevention efforts., |
Maternal and neonatal outcomes among women with HIV infection and their infants in Malawi
Chevalier MS , King CC , Ellington S , Wiener J , Kayira D , Chasela CS , Jamieson DJ , Kourtis AP . Int J Gynaecol Obstet 2017 137 (3) 282-289 OBJECTIVE: To describe maternal and neonatal morbidity and mortality among women with HIV infection and their infants. METHODS: A secondary analysis was undertaken of data obtained in the BAN Study, a trial of postnatal antiretrovirals among pregnant women with HIV infection enrolled in 2004-2010. Mothers and infants had 13 scheduled visits through 48 weeks of follow-up. Serious maternal morbidity and mortality were examined at delivery (n=2791), from delivery to 6 weeks later (n=2369) and from 7 to 48 weeks (n=1980). Neonatal morbidity and mortality were examined (n=2685). RESULTS: Of 2791 deliveries, 169 (6.1%) were by cesarean (153 emergency). Compared with women with vaginal delivery, those with cesarean delivery had lower prenatal HIV viral loads (P=0.016) and increased odds of pre-eclampsia/eclampsia (odds ratio [OR] 10.8, 95% CI 4.4-26.8). Women with cesarean delivery also had increased odds of serious infection with 14 days of delivery (OR 3.0, 95% CI 1.3-7.4) and severe anemia (grade 3 or 4) by 6 weeks (OR 6.7, 95% CI 2.3-19.1). Infants born by cesarean had increased odds of a low 5-minute Apgar score (OR 8.1, 95% CI 3.5-18.6) and admission to an intensive care unit (OR 5.4, 95% CI 3.7-7.8). CONCLUSION: Odds of serious maternal and neonatal morbidity were higher after cesarean than vaginal delivery, despite lower maternal viral loads. This article is protected by copyright.

Progress toward strengthening national blood transfusion services - 14 countries, 2011-2014
Chevalier MS , Kuehnert M , Basavaraju SV , Bjork A , Pitman JP . MMWR Morb Mortal Wkly Rep 2016 65 (5) 115-9 Blood transfusion is a life-saving medical intervention; however, challenges to the recruitment of voluntary, unpaid or otherwise nonremunerated whole blood donors and insufficient funding of national blood services and programs have created obstacles to collecting adequate supplies of safe blood in developing countries. Since 2004, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) has provided approximately $437 million in bilateral financial support to strengthen national blood transfusion services in 14 countries in sub-Saharan Africa and the Caribbean that have high prevalence rates of human immunodeficiency virus (HIV) infections. CDC analyzed routinely collected surveillance data on annual blood collections and HIV prevalence among donated blood units for 2011-2014. This report updates previous CDC reports on progress made by these 14 PEPFAR-supported countries in blood safety, summarizes challenges facing countries as they strive to meet World Health Organization (WHO) targets, and documents progress toward achieving the WHO target of 100% voluntary, nonremunerated blood donors by 2020. During 2011-2014, overall blood collections among the 14 countries increased by 19%; countries with 100% voluntary, nonremunerated blood donations remained stable at eight, and, despite high national HIV prevalence rates, 12 of 14 countries reported an overall decrease in donated blood units that tested positive for HIV. Achieving safe and adequate national blood supplies remains a public health priority for WHO and countries worldwide. Continued success in improving blood safety and achieving WHO targets for blood quality and adequacy will depend on national government commitments to national blood transfusion services or blood programs through increased public financing and diversified funding mechanisms for transfusion-related activities. |
Active tracing and monitoring of contacts associated with the first cluster of Ebola in the United States
Chung WM , Smith JC , Weil LM , Hughes SM , Joyner SN , Hall EM , Ritch J , Srinath D , Goodman E , Chevalier MS , Epstein L , Hunter JC , Kallen AJ , Karwowski MP , Kuhar DT , Smith C , Petersen LR , Mahon BE , Lakey DL , Schrag SJ . Ann Intern Med 2015 163 (3) 164-73 BACKGROUND: Following hospitalization of the first patient with Ebola virus disease diagnosed in the United States on 28 September 2014, contact tracing methods for Ebola were implemented. OBJECTIVE: To identify, risk-stratify, and monitor contacts of patients with Ebola. DESIGN: Descriptive investigation. SETTING: Dallas County, Texas, September to November 2014. PARTICIPANTS: Contacts of symptomatic patients with Ebola. MEASUREMENTS: Contact identification, exposure risk classification, symptom development, and Ebola. RESULTS: The investigation identified 179 contacts, 139 of whom were contacts of the index patient. Of 112 health care personnel (HCP) contacts of the index case, 22 (20%) had known unprotected exposures and 37 (30%) did not have known unprotected exposures but interacted with a patient or contaminated environment on multiple days. Transmission was confirmed in 2 HCP who had substantial interaction with the patient while wearing personal protective equipment. These HCP had 40 additional contacts. Of 20 community contacts of the index patient or the 2 HCP, 4 had high-risk exposures. Movement restrictions were extended to all 179 contacts; 7 contacts were quarantined. Seven percent (14 of 179) of contacts (1 community contact and 13 health care contacts) were evaluated for Ebola during the monitoring period. LIMITATION: Data cannot be used to infer whether in-person direct active monitoring is superior to active monitoring alone for early detection of symptomatic contacts. CONCLUSION: Contact tracing and monitoring approaches for Ebola were adapted to account for the evolving understanding of risks for unrecognized HCP transmission. HCP contacts in the United States without known unprotected exposures should be considered as having a low (but not zero) risk for Ebola and should be actively monitored for symptoms. Core challenges of contact tracing for high-consequence communicable diseases included rapid comprehensive contact identification, large-scale direct active monitoring of contacts, large-scale application of movement restrictions, and necessity of humanitarian support services to meet nonclinical needs of contacts. PRIMARY FUNDING SOURCE: None. |
Addressing needs of contacts of Ebola patients during an investigation of an Ebola cluster in the United States - Dallas, Texas, 2014
Smith CL , Hughes SM , Karwowski MP , Chevalier MS , Hall E , Joyner SN , Ritch J , Smith JC , Weil LM , Chung WM , Schrag S , Santibanez S . MMWR Morb Mortal Wkly Rep 2015 64 (5) 121-123 The first imported case of Ebola virus disease (Ebola) diagnosed in the United States was confirmed on September 30, 2014; two health care workers who cared for this patient subsequently developed Ebola. Since then, local, state, and federal health officials have continued to prepare for future imported cases, including developing strategies to identify and monitor persons who have had contact with an Ebola patient. This report describes some of the needs of persons who were contacts of Ebola patients in Texas. It is based on requests received from contacts in the course of daily contact tracing interactions and on how those needs were met through community partnerships. Meeting the needs of contacts of the Ebola patients was essential to successful contact tracing, which is critical to interrupting transmission. Although a formal needs assessment of contacts was not conducted, this report provides important information for preparing for an importation of Ebola. Anticipating the nonclinical needs of persons under public health surveillance includes addressing potential concerns about housing, transportation, education, employment, food, and other household needs. Ensuring necessary supports are in place for persons who are asked to refrain from entering public venues can impact their willingness to comply with voluntary and mandated quarantine orders. Engagement with a wide range of community partners, including businesses, schools, charitable foundations, community and faith-based organizations, and mental health resources would enhance public health emergency preparedness for Ebola by readying resources to meet these potential needs. |
Ebola virus disease cluster in the United States - Dallas County, Texas, 2014
Chevalier MS , Chung W , Smith J , Weil LM , Hughes SM , Joyner SN , Hall E , Srinath D , Ritch J , Thathiah P , Threadgill H , Cervantes D , Lakey DL . MMWR Morb Mortal Wkly Rep 2014 63 (46) 1087-8 Since March 10, 2014, Guinea, Liberia, and Sierra Leone have experienced the largest known Ebola virus disease (Ebola) epidemic with approximately 13,000 persons infected as of October 28, 2014. Before September 25, 2014, only four patients with Ebola had been treated in the United States; all of these patients had been diagnosed in West Africa and medically evacuated to the United States for care. |
