Disparities in tuberculosis incidence by race and ethnicity among the U.S.-born population in the United States, 2011 to 2021 : An analysis of national disease registry data
Li Y , Regan M , Swartwood NA , Barham T , Beeler Asay GR , Cohen T , Hill AN , Horsburgh CR Jr , Khan A , Marks SM , Myles RL , Salomon JA , Self JL , Menzies NA . Ann Intern Med 2024 BACKGROUND: Elevated tuberculosis (TB) incidence rates have recently been reported for racial/ethnic minority populations in the United States. Tracking such disparities is important for assessing progress toward national health equity goals and implementing change. OBJECTIVE: To quantify trends in racial/ethnic disparities in TB incidence among U.S.-born persons. DESIGN: Time-series analysis of national TB registry data for 2011 to 2021. SETTING: United States. PARTICIPANTS: U.S.-born persons stratified by race/ethnicity. MEASUREMENTS: TB incidence rates, incidence rate differences, and incidence rate ratios compared with non-Hispanic White persons; excess TB cases (calculated from incidence rate differences); and the index of disparity. Analyses were stratified by sex and by attribution of TB disease to recent transmission and were adjusted for age, year, and state of residence. RESULTS: In analyses of TB incidence rates for each racial/ethnic population compared with non-Hispanic White persons, incidence rate ratios were as high as 14.2 (95% CI, 13.0 to 15.5) among American Indian or Alaska Native (AI/AN) females. Relative disparities were greater for females, younger persons, and TB attributed to recent transmission. Absolute disparities were greater for males. Excess TB cases in 2011 to 2021 represented 69% (CI, 66% to 71%) and 62% (CI, 60% to 64%) of total cases for females and males, respectively. No evidence was found to indicate that incidence rate ratios decreased over time, and most relative disparity measures showed small, statistically nonsignificant increases. LIMITATION: Analyses assumed complete TB case diagnosis and self-report of race/ethnicity and were not adjusted for medical comorbidities or social determinants of health. CONCLUSION: There are persistent disparities in TB incidence by race/ethnicity. Relative disparities were greater for AI/AN persons, females, and younger persons, and absolute disparities were greater for males. Eliminating these disparities could reduce overall TB incidence by more than 60% among the U.S.-born population. PRIMARY FUNDING SOURCE: Centers for Disease Control and Prevention. |

BMC Infect Dis 2024 24 (1) 336 BACKGROUND: Data on the characteristics of individuals with mild and asymptomatic infections with different SARS-CoV-2 variants are limited. We therefore compared the characteristics of individuals infected with ancestral, Beta and Delta SARS-CoV-2 variants in South Africa. METHODS: We conducted a prospective cohort study in a rural and an urban site during July 2020-August 2021. Mid-turbinate nasal swabs were collected twice-weekly from household members irrespective of symptoms and tested for SARS-CoV-2 using real-time reverse transcription polymerase chain reaction (rRT-PCR). Differences in demographic and clinical characteristics, shedding and cycle threshold (Ct) value of infection episodes by variant were evaluated using multinomial regression. Overall and age-specific incidence rates of infection were compared by variant. RESULTS: We included 1200 individuals from 222 households and 648 rRT-PCR-confirmed infection episodes (66, 10% ancestral, 260, 40% Beta, 322, 50% Delta). Symptomatic proportion was similar for ancestral (7, 11%), Beta (44, 17%), and Delta (46, 14%) infections (p=0.4). After accounting for previous infection, peak incidence shifted to younger age groups in successive waves (40-59 years ancestral, 19-39 years Beta, 13-18 years Delta). On multivariable analysis, compared to ancestral, Beta infection was more common in individuals aged 5-12 years (vs 19-39)(adjusted odds ratio (aOR) 2.6, 95% confidence interval (CI)1.1-6.6) and PCR cycle threshold (Ct) value <30 (vs >35)(aOR 3.2, 95%CI 1.3-7.9), while Delta was more common in individuals aged <5 (aOR 6.7, 95%CI1.4-31.2) and 5-12 years (aOR 6.6 95%CI2.6-16.7)(vs 19-39) and Ct value <30 (aOR 4.5, 95%CI 1.3-15.5) and 30-35 (aOR 6.0, 95%CI 2.3-15.7)(vs >35). CONCLUSIONS: Consecutive SARS-CoV-2 waves with Beta and Delta variants were associated with a shift to younger individuals. Beta and Delta infections were associated with higher peak viral loads, potentially increasing infectiousness. |
Outpatient visits and antibiotic use due to higher valency pneumococcal vaccine serotypes
King LM , Andrejko KL , Kabbani S , Tartof SY , Hicks LA , Cohen AL , Kobayashi M , Lewnard JA . J Infect Dis 2024 BACKGROUND: In 2022-2023, 15- and 20-valent pneumococcal conjugate vaccines (PCV15/PCV20) were recommended for infants. We aimed to estimate the incidence of outpatient visits and antibiotic prescriptions in U.S. children (≤17 years) from 2016-2019 for acute otitis media, pneumonia, and sinusitis associated with PCV15- and PCV20-additional (non-PCV13) serotypes to quantify PCV15/20 potential impacts. METHODS: We estimated the incidence of PCV15/20-additional serotype-attributable visits and antibiotic prescriptions as the product of all-cause incidence rates, derived from national healthcare surveys and MarketScan databases, and PCV15/20-additional serotype-attributable fractions. We estimated serotype-specific attributable fractions using modified vaccine-probe approaches incorporating incidence changes post-PCV13 and ratios of PCV13 versus PCV15/20 serotype frequencies, estimated through meta-analyses. RESULTS: Per 1000 children annually, PCV15-additional serotypes accounted for an estimated 2.7 (95% confidence interval 1.8-3.9) visits and 2.4 (1.6-3.4) antibiotic prescriptions. PCV20-additional serotypes resulted in 15.0 (11.2-20.4) visits and 13.2 (9.9-18.0) antibiotic prescriptions annually per 1,000 children. PCV15/20-additional serotypes account for 0.4% (0.2-0.6%) and 2.1% (1.5-3.0%) of pediatric outpatient antibiotic use. CONCLUSIONS: Compared with PCV15-additional serotypes, PCV20-additional serotypes account for >5 times the burden of visits and antibiotic prescriptions. Higher-valency PCVs, especially PCV20, may contribute to preventing pediatric pneumococcal respiratory infections and antibiotic use. |

A peer-to-peer collaborative learning approach for the implementation of evidence-informed interventions to improve HIV-related health outcomes
Keuroghlian AS , Marc L , Goldhammer H , Massaquoi M , Downes A , Stango J , Bryant H , Cahill S , Yen J , Perez AC , Head JM , Mayer KH , Myers J , Rebchook GM , Bourdeau B , Psihopaidas D , Chavis NS , Cohen SM . AIDS Behav 2024 The nationwide scale-up of evidence-based and evidence-informed interventions has been widely recognized as a crucial step in ending the HIV epidemic. Although the successful delivery of interventions may involve intensive expert training, technical assistance (TA), and dedicated funding, most organizations attempt to replicate interventions without access to focused expert guidance. Thus, there is a grave need for initiatives that meaningfully address HIV health disparities while addressing these inherent limitations. Here, the Health Resources and Services Administration HIV/AIDS Bureau (HRSA HAB) initiative Using Evidence-Informed Interventions to Improve HIV Health Outcomes among People Living with HIV (E2i) piloted an alternative approach to implementation that de-emphasized expert training to naturalistically simulate the experience of future HIV service organizations with limited access to TA. The E2i approach combined the HAB-adapted Institute for Healthcare Improvement's Breakthrough Series Collaborative Learning Model with HRSA HAB's Implementation Science Framework, to create an innovative multi-tiered system of peer-to-peer learning that was piloted across 11 evidence-informed interventions at 25 Ryan White HIV/AIDS Program sites. Four key types of peer-to-peer learning exchanges (i.e., intervention, site, staff role, and organization specific) took place at biannual peer learning sessions, while quarterly intervention cohort calls and E2i monthly calls with site staff occurred during the action periods between learning sessions. Peer-to-peer learning fostered both experiential learning and community building and allowed site staff to formulate robust site-specific action plans for rapid cycle testing between learning sessions. Strategies that increase the effectiveness of interventions while decreasing TA could provide a blueprint for the rapid uptake and integration of HIV interventions nationwide. |

Kapoor M , Pringle K , Kumar A , Dearth S , Liu L , Lovchik J , Perez O , Pontones P , Richards S , Yeadon-Fagbohun J , Breakwell L , Chea N , Cohen NJ , Schneider E , Erdman D , Haynes L , Pallansch M , Tao Y , Tong S , Gerber S , Swerdlow D , Feikin DR . Clin Infect Dis 2014 59 (11) 1511-8 BACKGROUND: The Middle East respiratory syndrome coronavirus (MERS-CoV) was discovered September 2012 in the Kingdom of Saudi Arabia (KSA). The first US case of MERS-CoV was confirmed on 2 May 2014. METHODS: We summarize the clinical symptoms and signs, laboratory and radiologic findings, and MERS-CoV-specific tests. RESULTS: The patient is a 65-year-old physician who worked in a hospital in KSA where MERS-CoV patients were treated. His illness onset included malaise, myalgias, and low-grade fever. He flew to the United States on day of illness (DOI) 7. His first respiratory symptom, a dry cough, developed on DOI 10. On DOI 11, he presented to an Indiana hospital as dyspneic, hypoxic, and with a right lower lobe infiltrate on chest radiography. On DOI 12, his serum tested positive by real-time reverse transcription polymerase chain reaction (rRT-PCR) for MERS-CoV and showed high MERS-CoV antibody titers, whereas his nasopharyngeal swab was rRT-PCR negative. Expectorated sputum was rRT-PCR positive the following day, with a high viral load (5.31 × 10(6) copies/mL). He was treated with antibiotics, intravenous immunoglobulin, and oxygen by nasal cannula. He was discharged on DOI 22. The genome sequence was similar (>99%) to other known MERS-CoV sequences, clustering with those from KSA from June to July 2013. CONCLUSIONS: This patient had a prolonged nonspecific prodromal illness before developing respiratory symptoms. Both sera and sputum were rRT-PCR positive when nasopharyngeal specimens were negative. US clinicians must be vigilant for MERS-CoV in patients with febrile and/or respiratory illness with recent travel to the Arabian Peninsula, especially among healthcare workers. |
Estimated rates of progression to tuberculosis disease for persons infected with Mycobacterium tuberculosis in the United States
Ekramnia M , Li Y , Haddad MB , Marks SM , Kammerer JS , Swartwood NA , Cohen T , Miller JW , Horsburgh CR , Salomon JA , Menzies NA . Epidemiology 2024 35 (2) 164-173 BACKGROUND: In the United States, over 80% of tuberculosis (TB) disease cases are estimated to result from reactivation of latent TB infection (LTBI) acquired more than 2 years previously ("reactivation TB"). We estimated reactivation TB rates for the US population with LTBI, overall, by age, sex, race-ethnicity, and US-born status, and for selected comorbidities (diabetes, end-stage renal disease, and HIV). METHODS: We collated nationally representative data for 2011-2012. Reactivation TB incidence was based on TB cases reported to the National TB Surveillance System that were attributed to LTBI reactivation. Person-years at risk of reactivation TB were calculated using interferon-gamma release assay (IGRA) positivity from the National Health and Nutrition Examination Survey, published values for interferon-gamma release assay sensitivity and specificity, and population estimates from the American Community Survey. RESULTS: For persons aged ≥6 years with LTBI, the overall reactivation rate was estimated as 0.072 (95% uncertainty interval: 0.047, 0.12) per 100 person-years. Estimated reactivation rates declined with age. Compared to the overall population, estimated reactivation rates were higher for persons with diabetes (adjusted rate ratio [aRR] = 1.6 [1.5, 1.7]), end-stage renal disease (aRR = 9.8 [5.4, 19]), and HIV (aRR = 12 [10, 13]). CONCLUSIONS: In our study, individuals with LTBI faced small, non-negligible risks of reactivation TB. Risks were elevated for individuals with medical comorbidities that weaken immune function. |

Acta Neuropathol 2024 147 (1) 17 Definitive diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD) relies on the examination of brain tissues for the pathological prion protein (PrP(Sc)). Our previous study revealed that PrP(Sc)-seeding activity (PrP(Sc)-SA) is detectable in skin of sCJD patients by an ultrasensitive PrP(Sc) seed amplification assay (PrP(Sc)-SAA) known as real-time quaking-induced conversion (RT-QuIC). A total of 875 skin samples were collected from 2 cohorts (1 and 2) at autopsy from 2-3 body areas of 339 cases with neuropathologically confirmed prion diseases and non-sCJD controls. The skin samples were analyzed for PrP(Sc)-SA by RT-QuIC assay. The results were compared with demographic information, clinical manifestations, cerebrospinal fluid (CSF) PrP(Sc)-SA, other laboratory tests, subtypes of prion diseases defined by the methionine (M) or valine (V) polymorphism at residue 129 of PrP, PrP(Sc) types (#1 or #2), and gene mutations in deceased patients. RT-QuIC assays of the cohort #1 by two independent laboratories gave 87.3% or 91.3% sensitivity and 94.7% or 100% specificity, respectively. The cohort #2 showed sensitivity of 89.4% and specificity of 95.5%. RT-QuIC of CSF available from 212 cases gave 89.7% sensitivity and 94.1% specificity. The sensitivity of skin RT-QuIC was subtype dependent, being highest in sCJDVV1-2 subtype, followed by VV2, MV1-2, MV1, MV2, MM1, MM1-2, MM2, and VV1. The skin area next to the ear gave highest sensitivity, followed by lower back and apex of the head. Although no difference in brain PrP(Sc)-SA was detected between the cases with false negative and true positive skin RT-QuIC results, the disease duration was significantly longer with the false negatives [12.0 ± 13.3 (months, SD) vs. 6.5 ± 6.4, p < 0.001]. Our study validates skin PrP(Sc)-SA as a biomarker for the detection of prion diseases, which is influenced by the PrP(Sc) types, PRNP 129 polymorphisms, dermatome sampled, and disease duration. |
Clinical and serologic phenotyping and damage indices in patients with systemic lupus erythematosus with and without fibromyalgia
Corbitt K , Carlucci PM , Cohen B , Masson M , Saxena A , Belmont HM , Tseng CE , Barbour KE , Gold H , Buyon J , Izmirly P . ACR Open Rheumatol 2024 OBJECTIVE: Given fibromyalgia (FM) frequently co-occurs with autoimmune disease, this study was initiated to objectively evaluate FM in a multiracial/ethnic cohort of patients with systemic lupus erythematosus (SLE). METHODS: Patients with SLE were screened for FM using the 2016 FM classification criteria during an in-person rheumatologist visit. We evaluated hybrid Safety of Estrogens in Lupus National Assessment (SELENA)-SLE Disease Activity Index (SLEDAI) scores, SLE classification criteria, and Systemic Lupus International Collaborating Clinics damage index. We compared patients with and without FM and if differences were present, compared patients with FM with patients with non-FM related chronic pain. RESULTS: 316 patients with SLE completed the FM questionnaire. 55 (17.4%) met criteria for FM. The racial composition of patients with FM differed from those without FM (P = 0.023), driven by fewer Asian patients having FM. There was no difference in SLE disease duration, SELENA-SLEDAI score, or active serologies. There was more active arthritis in the FM group (16.4%) versus the non-FM group (1.9%) (P < 0.001). The Widespread Pain Index and Symptom Severity Score did not correlate with degree of SLE activity (r = -0.016; 0.107) among patients with FM or non-FM chronic pain (r = 0.009; -0.024). Regarding criteria, patients with FM had less nephritis and more malar rash. Systemic Lupus International Collaborating Clinics damage index did not differ between groups. CONCLUSION: Except for arthritis, patients with SLE with FM are not otherwise clinically or serologically distinguishable from those without FM, and Widespread Pain Index and Symptom Severity Score indices do not correlate with SLEDAI. These observations support the importance of further understanding the underlying biology of FM in SLE. |
Racial and ethnic disparities in diagnosis and treatment outcomes among US-born people diagnosed with tuberculosis, 2003-19: an analysis of national surveillance data
Regan M , Li Y , Swartwood NA , Barham T , Asay GRB , Cohen T , Hill AN , Horsburgh CR , Khan A , Marks SM , Myles RL , Salomon JA , Self JL , Menzies NA . Lancet Public Health 2024 9 (1) e47-e56 BACKGROUND: Persistent racial and ethnic disparities in tuberculosis incidence exist in the USA, however, less is known about disparities along the tuberculosis continuum of care. This study aimed to describe how race and ethnicity are associated with tuberculosis diagnosis and treatment outcomes. METHODS: In this analysis of national surveillance data, we extracted data from the US National Tuberculosis Surveillance System on US-born patients with tuberculosis during 2003-19. To estimate the association between race and ethnicity and tuberculosis diagnosis (diagnosis after death, cavitation, and sputum smear positivity) and treatment outcomes (treatment for more than 12 months, treatment discontinuation, and death during treatment), we fitted log-binomial regression models adjusting for calendar year, sex, age category, and regional division. Race and ethnicity were defined based on US Census Bureau classification as White, Black, Hispanic, Asian, American Indian or Alaska Native, Native Hawaiian or Pacific Islander, and people of other ethnicities. We quantified racial and ethnic disparities as adjusted relative risks (aRRs) using non-Hispanic White people as the reference group. We also calculated the Index of Disparity as a summary measure that quantifies the dispersion in a given outcome across all racial and ethnic groups, relative to the population mean. We estimated time trends in each outcome to evaluate whether disparities were closing or widening. FINDINGS: From 2003 to 2019, there were 72 809 US-born individuals diagnosed with tuberculosis disease of whom 72 369 (35·7% women and 64·3% men) could be included in analyses. We observed an overall higher risk of any adverse outcome (defined as diagnosis after death, treatment discontinuation, or death during treatment) for non-Hispanic Black people (aRR 1·27, 95% CI 1·22-1·32), Hispanic people (1·20, 1·14-1·27), and American Indian or Alaska Native people (1·24, 1·12-1·37), relative to non-Hispanic White people. The Index of Disparity for this summary outcome remained unchanged over the study period. INTERPRETATION: This study, based on national surveillance data, indicates racial and ethnic disparaties among US-born tuberculosis patients along the tuberculosis continuum of care. Initiatives are needed to reduce diagnostic delays and improve treatment outcomes for US-born racially marginalised people in the USA. FUNDING: US Centers for Disease Control and Prevention. |

Incidence and transmission of respiratory syncytial virus in urban and rural South Africa, 2017-2018
Cohen C , Kleynhans J , Moyes J , McMorrow ML , Treurnicht FK , Hellferscee O , Wolter N , Martinson NA , Kahn K , Lebina L , Mothlaoleng K , Wafawanaka F , Gómez-Olivé FX , Mkhencele T , Mathunjwa A , Carrim M , Mathee A , Piketh S , Language B , von Gottberg A , Tempia S . Nat Commun 2024 15 (1) 116 Data on respiratory syncytial virus (RSV) incidence and household transmission are limited. To describe RSV incidence and transmission, we conducted a prospective cohort study in rural and urban communities in South Africa over two seasons during 2017-2018. Nasopharyngeal swabs were collected twice-weekly for 10 months annually and tested for RSV using PCR. We tested 81,430 samples from 1,116 participants in 225 households (follow-up 90%). 32% (359/1116) of individuals had ≥1 RSV infection; 10% (37/359) had repeat infection during the same season, 33% (132/396) of infections were symptomatic, and 2% (9/396) sought medical care. Incidence was 47.2 infections/100 person-years and highest in children <5 years (78.3). Symptoms were commonest in individuals aged <12 and ≥65 years. Individuals 1-12 years accounted for 55% (134/242) of index cases. Household cumulative infection risk was 11%. On multivariable analysis, index cases with ≥2 symptoms and shedding duration >10 days were more likely to transmit; household contacts aged 1-4 years vs. ≥65 years were more likely to acquire infection. Within two South African communities, RSV attack rate was high, and most infections asymptomatic. Young children were more likely to introduce RSV into the home, and to be infected. Future studies should examine whether vaccines targeting children aged <12 years could reduce community transmission. |
Genomic characterization of Bordetella pertussis in South Africa, 2015-2019
Moosa F , du Plessis M , Weigand MR , Peng Y , Mogale D , de Gouveia L , Nunes MC , Madhi SA , Zar HJ , Reubenson G , Ismail A , Tondella ML , Cohen C , Walaza S , von Gottberg A , Wolter N . Microb Genom 2023 9 (12) Pertussis remains a public health concern in South Africa, with an increase in reported cases and outbreaks in recent years. Whole genome sequencing was performed on 32 Bordetella pertussis isolates sourced from three different surveillance programmes in South Africa between 2015 and 2019. Genome sequences were characterized using multilocus sequence typing, vaccine antigen genes (ptxP, ptxA, ptxB, prn and fimH) and overall genome structure. All isolates were sequence type 2 and harboured the pertussis toxin promoter allele ptxP3. The dominant genotype was ptxP3-ptxA1-ptxB2-prn2-fimH2 (31/32, 96.9 %), with no pertactin-deficient or other mutations in vaccine antigen genes identified. Amongst 21 isolates yielding closed genome assemblies, eight distinct genome structures were detected, with 61.9 % (13/21) of the isolates exhibiting three predominant structures. Increases in case numbers are probably not due to evolutionary changes in the genome but possibly due to other factors such as the cyclical nature of B. pertussis disease, waning immunity due to the use of acellular vaccines and/or population immunity gaps. |
ACIP Updates: Recommendations for Use of 20-Valent Pneumococcal Conjugate Vaccine in Children - United States, 2023

J Pediatric Infect Dis Soc 2023 12 (12) 646-651 We enrolled 1323 hospitalised infants aged <1 year in 2016-2018, and examined the association between HIV status and in-hospital mortality. After controlling for confounders, HIV exposed uninfected infants did not have an increased risk of mortality, whereas infants living with HIV had four-times greater risk compared to HIV uninfected infants. |
Advancing data capacity for economic outcomes in patient-centered outcomes research: Challenges and opportunities
Timbie JW , Reynolds KA , Evans EL , Brown DS , Cohen JW , Darien G , DeVoe JE , Grosse SD , Holve E , Meltzer DO , Merritt JG , Neumann PJ , Yabroff KR , Smith SR . Med Care 2023 61 S161-s165 The economic impacts of health care treatments and services on individuals and their families are central to many decisions people make about the use of health care. However, without the high-quality data needed to generate evidence on the clinical effectiveness and economic impacts of an intervention, decision-makers are generally limited in their ability to make informed health care decisions that reflect patient values and preferences. The importance of evidence on economic impacts, including nonmedical costs and work-related impacts, was recognized in the reauthorization of the Patient-centered Outcomes Research Trust Fund,1 which added economic outcomes to the range of outcomes that should be considered as part of patient-centered outcomes research (PCOR). |
Prevalence of undiagnosed monkeypox virus infections during global mpox outbreak, United States, June-September 2022

Emerg Infect Dis 2023 29 (11) 2307-2314 Since May 2022, mpox has been identified in 108 countries without endemic disease; most cases have been in gay, bisexual, or other men who have sex with men. To determine number of missed cases, we conducted 2 studies during June-September 2022: a prospective serologic survey detecting orthopoxvirus antibodies among men who have sex with men in San Francisco, California, and a retrospective monkeypox virus PCR testing of swab specimens submitted for other infectious disease testing among all patients across the United States. The serosurvey of 225 participants (median age 34 years) detected 18 (8.0%) who were orthopoxvirus IgG positive and 3 (1.3%) who were also orthopoxvirus IgM positive. The retrospective PCR study of 1,196 patients (median age 30 years; 54.8% male) detected 67 (5.6%) specimens positive for monkeypox virus. There are likely few undiagnosed cases of mpox in regions where sexual healthcare is accessible and patient and clinician awareness about mpox is increased. |
The present and future of the adult pneumococcal vaccine program in the United States
Miwako Kobayashi , Cohen Adam L , Poehling Katherine A . NEJM Evidence 2023 2 (11) 11-11 Streptococcus pneumoniae (pneumococcus) is a common cause of bacterial respiratory infections, such as pneumonia, sinusitis, and acute otitis media, and it also causes invasive diseases (i.e., infection in a normally sterile site), such as meningitis and bacteremia, leading to substantial morbidity and mortality. Before the coronavirus disease 2019 (Covid-19) pandemic, it is estimated that ≥100,000 pneumococcal pneumonia hospitalizations, ≥30,000 invasive pneumococcal disease cases, and 3000 invasive pneumocococcal disease deaths occurred among U.S. adults in a year.1 Resurgence of non-SARS-CoV-2 respiratory virus infections was reported in the United States in late 2022, and preliminary invasive pneumocococcal disease incidence in late 2022 exceeded the pre--Covid-19 baseline incidence in children and young adults (Centers for Disease Control and Prevention Active Bacterial Core surveillance, unpublished data). Effective pneumococcal vaccines are available and have been used in many countries. Although children have been the focus of pneumococcal vaccination programs globally,2 pneumococcal vaccines have also been recommended for adults in the United States for more than 40 years. The Advisory Committee on Immunization Practices updated their adult pneumococcal vaccine recommendations in October 2022, the fifth time since 2012 (Table 1), with the goal of increasing population-level protection against pneumococcal disease as well as reducing disparities in pneumococcal disease burden among those at increased risk.3 What have we learned from the U.S. adult pneumococcal vaccine program, what are the remaining gaps, and how can we address these gaps in considering future U.S. pneumococcal vaccine recommendations? Adult Pneumococcal Vaccine Program in the United States Streptococcus pneumoniae (pneumococcus) is a common cause of bacterial respiratory infections leading to substantial morbidity and mortality. Here, Kobayashi et al. discuss the recently updated U.S. guidelines for adult pneumococcal vaccination. |
Quickstats: Percentage* of adults who used the internet in the past 12 months to communicate with a doctor or doctor's office,(†) by urbanization level(§) - National Health Interview Survey, United States, July-December 2022(¶)
Cohen RA , Wang X . MMWR Morb Mortal Wkly Rep 2023 72 (44) 1207 During July–December 2022, 41.5% of U.S. adults used the Internet in the past 12 months to communicate with a doctor or doctor’s office.

Assessment of the strengths and weaknesses of this evidence, and hence, the ability to synthesize it, has been limited by inadequate reporting of results. The STrengthening the REporting of Genetic Association (STREGA) studies initiative builds on the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement and provides additions to 12 of the 22 items on the STROBE checklist. The additions concern population stratification, genotyping errors, modeling haplotype variation, Hardy-Weinberg equilibrium, replication, selection of participants, rationale for choice of genes and variants, treatment effects in studying quantitative traits, statistical methods, relatedness, reporting of descriptive and outcome data, and the volume of data issues that are important to consider in genetic association studies. The STREGA recommendations do not prescribe or dictate how a genetic association study should be designed, but seek to enhance the transparency of its reporting, regardless of choices made during design, conduct, or analysis. |

Pneumococcal vaccine for adults aged 19 years: Recommendations of the Advisory Committee on Immunization Practices, United States, 2023
Kobayashi M , Pilishvili T , Farrar JL , Leidner AJ , Gierke R , Prasad N , Moro P , Campos-Outcalt D , Morgan RL , Long SS , Poehling KA , Cohen AL . MMWR Recomm Rep 2023 72 (3) 1-39 This report compiles and summarizes all published recommendations from CDC’s Advisory Committee on Immunization Practices (ACIP) for use of pneumococcal vaccines in adults aged ≥19 years in the United States. This report also includes updated and new clinical guidance for implementation from CDC. | | Before 2021, ACIP recommended 23-valent pneumococcal polysaccharide vaccine (PPSV23) alone (up to 2 doses), or both a single dose of 13-valent pneumococcal conjugate vaccine (PCV13) in combination with 1–3 doses of PPSV23 in series (PCV13 followed by PPSV23), for use in U.S. adults depending on age and underlying risk for pneumococcal disease. In 2021, two new pneumococcal conjugate vaccines (PCVs), a 15-valent and a 20-valent PCV (PCV15 and PCV20), were licensed for use in U.S. adults aged ≥18 years by the Food and Drug Administration. | | ACIP recommendations specify the use of either PCV20 alone or PCV15 in series with PPSV23 for all adults aged ≥65 years and for adults aged 19–64 years with certain underlying medical conditions or other risk factors who have not received a PCV or whose vaccination history is unknown. In addition, ACIP recommends use of either a single dose of PCV20 or ≥1 dose of PPSV23 for adults who have started their pneumococcal vaccine series with PCV13 but have not received all recommended PPSV23 doses. Shared clinical decision-making is recommended regarding use of a supplemental PCV20 dose for adults aged ≥65 years who have completed their recommended vaccine series with both PCV13 and PPSV23. | | Updated and new clinical guidance for implementation from CDC includes the recommendation for use of PCV15 or PCV20 for adults who have received PPSV23 but have not received any PCV dose. The report also includes clinical guidance for adults who have received 7-valent PCV (PCV7) only and adults who are hematopoietic stem cell transplant recipients. |
Tabby2: a user-friendly web tool for forecasting state-level TB outcomes in the United States
Swartwood NA , Testa C , Cohen T , Marks SM , Hill AN , Beeler Asay G , Cochran J , Cranston K , Randall LM , Tibbs A , Horsburgh CR Jr , Salomon JA , Menzies NA . BMC Med 2023 21 (1) 331 BACKGROUND: In the United States, the tuberculosis (TB) disease burden and associated factors vary substantially across states. While public health agencies must choose how to deploy resources to combat TB and latent tuberculosis infection (LTBI), state-level modeling analyses to inform policy decisions have not been widely available. METHODS: We developed a mathematical model of TB epidemiology linked to a web-based user interface - Tabby2. The model is calibrated to epidemiological and demographic data for the United States, each U.S. state, and the District of Columbia. Users can simulate pre-defined scenarios describing approaches to TB prevention and treatment or create their own intervention scenarios. Location-specific results for epidemiological outcomes, service utilization, costs, and cost-effectiveness are reported as downloadable tables and customizable visualizations. To demonstrate the tool's functionality, we projected trends in TB outcomes without additional intervention for all 50 states and the District of Columbia. We further undertook a case study of expanded treatment of LTBI among non-U.S.-born individuals in Massachusetts, covering 10% of the target population annually over 2025-2029. RESULTS: Between 2022 and 2050, TB incidence rates were projected to decline in all states and the District of Columbia. Incidence projections for the year 2050 ranged from 0.03 to 3.8 cases (median 0.95) per 100,000 persons. By 2050, we project that majority (> 50%) of TB will be diagnosed among non-U.S.-born persons in 46 states and the District of Columbia; per state percentages range from 17.4% to 96.7% (median 83.0%). In Massachusetts, expanded testing and treatment for LTBI in this population was projected to reduce cumulative TB cases between 2025 and 2050 by 6.3% and TB-related deaths by 8.4%, relative to base case projections. This intervention had an incremental cost-effectiveness ratio of $180,951 (2020 USD) per quality-adjusted life year gained from the societal perspective. CONCLUSIONS: Tabby2 allows users to estimate the costs, impact, and cost-effectiveness of different TB prevention approaches for multiple geographic areas in the United States. Expanded testing and treatment for LTBI could accelerate declines in TB incidence in the United States, as demonstrated in the Massachusetts case study. |
WHO Framework Convention on Tobacco Control learnings
Cohen JE , Myers ML , Ahluwalia IB . Health Secur 2023 21 (5) 428-429 We are pleased that the World Health Organization (WHO) is developing a pandemic treaty to improve the global response to future pandemics. In their article, De Luca and Ramirez1 rightly argue that a pandemic treaty should be informed by experiences with WHO's existing treaty, the WHO Framework Convention on Tobacco Control (WHO FCTC), which came into force in 2005. However, the authors have mischaracterized the WHO FCTC and made criticisms that could hinder a productive discussion about a treaty for pandemics. | | The authors identify a limited emphasis on “harm reduction” as a key limitation of the WHO FCTC. However, the treaty itself includes “harm reduction strategies” in its definition of tobacco control.2 As the authors indicate, harm reduction encompasses actions “aimed at reducing the negative effects of health behaviors without necessarily extinguishing the problematic health behaviors completely or permanently.”1,3 The WHO FCTC and its guidelines for implementation—which include requiring smoke-free public places; banning tobacco advertising, promotion, and sponsorship; and reducing the attractiveness of tobacco products by limiting flavoring agents—allow the continuation of product use, while reducing t |
