RESUMEN
In September 2022, CDC funded a nationwide program, Together TakeMeHome (TTMH), to expand distribution of HIV self-tests (HIVSTs) directly to consumers by mail through an online ordering portal. To publicize the availability of HIVSTs to priority audiences, particularly those disproportionately affected by HIV, CDC promoted this program through established partnerships and tailored resources from its Let's Stop HIV Together social marketing campaign. The online portal launched March 14, 2023, and through March 13, 2024, distributed 443,813 tests to 219,360 persons. Among 169,623 persons who answered at least one question on a postorder questionnaire, 67.9% of respondents were from priority audiences, 24.1% had never previously received testing for HIV, and 24.8% had not received testing in the past year. Among the subset of participants who initiated a follow-up survey, 88.3% used an HIVST themselves, 27.1% gave away an HIVST, 11.7% accessed additional preventive services, and 1.9% reported a new positive HIVST result. Mailed HIVST distribution can quickly reach large numbers of persons who have never received testing for HIV or have not received testing as often as is recommended. TTMH can help to achieve the goal of diagnosing HIV as early as possible and provides a path to other HIV prevention and care services. Clinicians, community organizations, and public health officials should be aware of HIVST programs, initiate discussions about HIV testing conducted outside their clinics or offices, and initiate follow-up services for persons who report a positive or negative HIVST result.

Dating apps are now used by the majority of MSM to meet sexual and romantic partners. While research has demonstrated an association between app use and greater number of sex partners and STIs, dating apps also pose an opportunity for intervention. By advocating for new and improved sexual health features on dating apps, Building Healthy Online Communities (BHOC) aims to increase communication about sexual health on the apps. As a follow-up to our previous paper assessing the uptake of sexual health-related profile options on dating apps through Emory's annual survey of 10,000 MSM in the US, BHOC and Emory partnered to explore the change in uptake over time, again through their annual survey. Among survey participants in 2021, 85% reported using dating apps to meet a partner in the past year, and among this group, 93% reported awareness of sexual health features, up from 77% in 2018 (p < 0.0001). 71% of app users who were aware of features in 2021 reported using one or more sexual health feature, up from 61% in 2018 (p < 0.0001). BHOC will continue to advocate for increased uptake of these features, especially among subgroups with lower levels of uptake.
RESUMEN
The immigrant population in the United States (U.S.) is rapidly growing; yet there is limited knowledge about how reasons for migrating to the U.S. are associated with HIV prevention behaviors. Using data from the American Men's Internet Survey (2018-2020), we performed a Latent Class Analysis (LCA) to identify patterns in reasons for migration among cisgender gay, bisexual, and other sexual minority men (SMM) who born outside the U.S. We used multivariable logistic regression controlling for demographic characteristics to assess class associations with the following in the past 12 months: condomless anal sex (CAS), illicit drug use, marijuana use, HIV testing, and PrEP use. LCA identified six distinct patterns in reasons for migration among the sample (n = 1,657): (1) Family and friends (14%); (2) Financial (17%); (3) Personal freedom related to being gay (10%); (4) Pursuit of opportunities while living openly as SMM (12%); (5) Educational purposes (18%); (6) Not my decision (29%). While HIV testing (range = 57.6-65.4%) and PrEP use (range = 15.6-21.4%) did not vary by class (p > .05 for all), CAS and illicit drug use were significantly different (p < .05). SMM who migrated to pursue opportunities while living openly and whose reasons were not their decision had greater odds of CAS than SMM who migrated for educational purposes (aOR:1.72, 95% confidence interval [95%CI]:1.15-2.59; 1.57, 1.13-2.19, respectively). Reasons for migration among SMM were associated with behaviors that can increase HIV risk, but not testing or PrEP. Push and pull factors related to migration should be considered when developing behavioral HIV interventions for immigrant SMM.
RESUMEN: La población inmigrante en los Estados Unidos (EE. UU.) está creciendo rápidamente; sin embargo, hay un conocimiento limitado acerca de cómo las razones para migrar a los EE. UU. se asocian con comportamientos de prevención del VIH. Utilizando datos del American Men's Internet Survey (20182020), realizamos un Análisis de Clases Latentes (ACL) para identificar patrones en las razones de migración entre hombres cisgénero gays, bisexuales y otros hombres de minorías sexuales (HMS) que reportaron haber nacido fuera de los EE. UU. Utilizamos regresión logística multivariable controlando las características demográficas para evaluar las asociaciones de clases con los siguientes comportamientos en los últimos 12 meses: sexo anal sin condón (SAC), consumo de drogas ilícitas, uso de marihuana, prueba del VIH y uso de PrEP. El ACL identificó seis patrones distintos en las razones de migración en la muestra (n = 1,657): (1) Familia y amigos (14%); (2) Motivos financieros (17%); (3) Libertad personal relacionada con ser gay (10%); (4) Búsqueda de oportunidades mientras viven abiertamente como HMS (12%); (5) Propósitos educativos (18%); (6) No fue decisión propia (29%). Mientras que las pruebas del VIH (rango = 57.665.4%) y el uso de PrEP (rango = 15.621.4%) no variaron según la clase (p > .05 para todos), el SAC y el consumo de drogas ilícitas fueron significativamente diferentes (p < .05). Los HMS que emigraron para perseguir oportunidades mientras vivían abiertamente, y aquellos cuyas razones no fueron decisión propia, tuvieron mayores probabilidades de tener SAC que los HMS que emigraron con propósitos educativos (razón de probabilidades ajustada [aOR]: 1.72, intervalo de confianza del 95% [IC 95%]: 1.152.59; 1.57, 1.132.19, respectivamente). Las razones de migración a los EE. UU. entre los HMS estuvieron asociadas con comportamientos que pueden aumentar el riesgo de VIH, pero no con pruebas o PrEP. Los factores que impulsan y atraen relacionados con la migración deben considerarse al desarrollar intervenciones de prevención del VIH para HMS inmigrantes.

This study measures changes in condomless anal sex (CAS) among HIV-negative men who have sex with men (MSM) who are not taking pre-exposure prophylaxis (PrEP). It considers the 2014-2019 cycles of the American Men's Internet Survey, a serial, cross-sectional web-based survey of US cisgender MSM aged ≥ 15 years, in which ~ 10% of each year's sample is drawn from the previous year. Among those surveyed for 2 years who remained HIV-negative and off PrEP, reports of having any CAS and of CAS partner number were compared across years. We disaggregated by partner HIV status, and considered demographic predictors. The overall population saw a significant 2.2 percentage-point (pp) increase in reports of any CAS year-over-year. Sub-populations with the largest year-on-year increases were 15-24-year-olds (5.0-pp) and Hispanic respondents (5.1-pp), with interaction (young Hispanic respondents = 12.8-pp). On the relative scale, these numbers correspond to 3.2%, 7.2%, 7.3% and 18.7%, respectively. Absolute increases were concentrated among partners reported as HIV-negative. Multivariable analyses for CAS initiation found effects concentrated among Hispanic and White youth and residents of fringe counties of large metropolitan areas. CAS partner number increases were similarly predicted by Hispanic identity and young age. Although condom use remains more common than PrEP use, increasing CAS among MSM not on PrEP suggests potential new HIV transmission pathways. Concentration of increases among 18-24-year-old MSM portends future increases in the proportion of newly diagnosed HIV that occur among youth. Concentration among young Hispanic MSM will likely expand existing disparities. Although reducing barriers to PrEP remains vital, condom promotion for MSM remains a key public health practice and appears to be missing key audiences. LGBTQ+-inclusive sex education is one avenue for enhancing these efforts.

BACKGROUND: Pre-exposure prophylaxis (PrEP) to prevent HIV is severely underutilized among sexually minoritized men (SMM). Inequitable access to PrEP-prescribing facilities and providers is a critical barrier to PrEP uptake among SMM. Integrating HIV prevention services, such as PrEP screening, into pharmacy-based settings is a viable solution to addressing HIV inequities in the US. We aimed to examine willingness to obtain PrEP screening in a pharmacy and its associated correlates, leveraging Andersen's Healthcare Utilization Model (AHUM), among a national sample of SMM in the U.S. METHODS: Data from the 2020 American Men's Internet Survey, an annual online survey among SMM, were analyzed. Drawing on AHUM-related constructs, we used a modified stepwise Poisson regression with robust variance estimates to examine differences in willingness to screen for PrEP in a pharmacy. Estimated prevalence ratios (PR) were calculated with 95% confidence intervals (CI95%). RESULTS: Out of 10,816 men, most (76%) were willing to screen for PrEP in a pharmacy. Participants were more willing to screen for PrEP in a pharmacy if they (1) had a general willingness to use PrEP (PR = 1.52; CI95% =1.45, 1.59); (2) felt comfortable speaking with pharmacy staff about PrEP (PR = 2.71; CI95% =2.47, 2.98); and (3) had HIV-related concerns (PR = 1.04; CI95% =1.02, 1.06). There were no observed differences in men's willingness to screen for PrEP in a pharmacy by race/ethnicity, education level, annual household income, nor insurance status. CONCLUSIONS: Strategically offering PrEP screening in pharmacies could mitigate access-related barriers to HIV prevention services among SMM, particularly across various sociodemographic domains. Importantly, this approach has vitally important implications for addressing broader inequities in HIV prevention. Future studies should examine strategies to successfully integrate PrEP screenings in pharmacies among diverse populations, especially among those at elevated risk for HIV.

BACKGROUND: HIV molecular epidemiology (HIV ME) can support the early detection of emerging clusters of new HIV infections by combining HIV sequence data routinely obtained during the clinical treatment of people living with HIV with behavioral, geographic, and sociodemographic information. While information about emerging clusters promises to facilitate HIV prevention and treatment efforts, the use of this data also raises several ethical concerns. We sought to assess how those working on the frontlines of HIV ME, specifically public health practitioners (PHPs) and researchers, prioritized these issues. METHODS: Ethical issues were identified through literature review, qualitative in-depth interviews, and stakeholder engagement. PHPs and researchers using HIV ME prioritized the issues using best-worst scaling (BWS). A balanced incomplete block design was used to generate 11 choice tasks each consisting of a sub-set of 5 ethical concerns. In each task, respondents were asked to assess the most and least concerning issue. Data were analyzed using conditional logit, with a Swait-Louviere test of poolability. Latent class analysis was then used to explore preference heterogeneity. RESULTS: In total, 57 respondents completed the BWS experiment May-June 2023 with the Swait-Louviere test indicating that researchers and PHPs could be pooled (p = 0.512). Latent class analysis identified two classes, those highlighting "Harms" (n = 29) (prioritizing concerns about potential risk of legal prosecution, individual harm, and group stigma) and those highlighting "Utility" (n = 28) (prioritizing concerns about limited evidence, resource allocation, non-disclosure of data use for HIV ME, and the potential to infer the directionality of HIV transmission). There were no differences in the characteristics of members across classes. CONCLUSIONS: The ethical issues of HIV ME vary in importance among stakeholders, reflecting different perspectives on the potential impact and usefulness of the data. Knowing these differences exist can directly inform the focus of future deliberations about the policies and practices of HIV ME in the United States.

While pre-exposure prophylaxis (PrEP) has demonstrated efficacy in preventing HIV transmission, disparities in access persist in the United States, especially among Hispanic/Latinx sexual minority men (SMM). Language barriers and differences in how Latinx SMM obtain information may impact access to PrEP and HIV prevention. This study used data from the 2021 American Men's Internet Survey (AMIS) to examine differences in communication networks and PrEP use among Latinx SMM by primary language (Spanish vs. English). We examined the associations between Latinx SMM's individual- and meso-level communication networks and PrEP-related outcomes using modified Poisson regression with robust variances. Spanish-speaking Latinx SMM in the study were less likely to test for HIV, be aware of PrEP, and use daily PrEP, compared to English-speaking participants. Sexuality disclosure to a healthcare provider was positively associated with PrEP uptake among all participants and predicted STI testing over the past 12 months among English-speaking Latinx SMM. Findings highlight disparities in PrEP awareness and uptake among Latinx SMM, especially among those whose primary language is Spanish. Addressing these disparities through targeted interventions, including improved communication with healthcare providers, may help facilitate PrEP access and use in this population.

ABSTRACT: Mpox vaccination is recommended for persons exposed to or at risk for mpox. Approximately 25% of an online sample of men who have sex with men (MSM) with presumed mpox exposure were vaccinated (≥1 dose). Vaccination was higher among younger MSM, MSM concerned about mpox, or MSM reporting sexual risk behaviors. Incorporating mpox vaccination into routine sexual health care and increasing 2-dose vaccination uptake is essential to preventing mpox acquisition, improving MSM sexual health, and averting future mpox outbreaks.

At-home rapid antigen COVID-19 tests were first authorized by the Food and Drug Administration in late 2020 (1-3). In January 2022, the White House launched COVIDTests.gov, which made all U.S. households eligible to receive free-to-the-user at-home test kits distributed by the U.S. Postal Service (2). By May 2022, more than 70 million test kit packages had been shipped to households across the United States (2); however, how these kits were used, and which groups were using them, has not been reported. Data from a national probability survey of U.S. households (COVIDVu), collected during April-May 2022, were used to evaluate awareness about and use of these test kits (4). Most respondent households (93.8%) were aware of the program, and more than one half (59.9%) had ordered kits. Among persons who received testing for COVID-19 during the preceding 6 months, 38.3% used a COVIDTests.gov kit. Among kit users, 95.5% rated the experience as acceptable, and 23.6% reported being unlikely to have tested without the COVIDTests.gov program. Use of COVIDTests.gov kits was similar among racial and ethnic groups (42.1% non-Hispanic Black or African American [Black]; 41.5% Hispanic or Latino [Hispanic]; 34.8% non-Hispanic White [White]; and 53.7% non-Hispanic other races [other races]). Use of other home COVID-19 tests differed by race and ethnicity (11.8% Black, 44.4% Hispanic, 45.8% White, 43.8% other races). Compared with White persons, Black persons were 72% less likely to use other home test kits (adjusted relative risk [aRR] = 0.28; 95% CI = 0.16-0.50). Provision of tests through this well-publicized program likely improved use of COVID-19 home testing and health equity in the United States, particularly among Black persons. National programs to address availability and accessibility of critical health services in a pandemic response have substantial health value.

Dating apps represent opportunities to implement sexual health interventions among gay, bisexual, and other men who have sex with men (MSM), particularly those who may avoid traditional health services due to intersecting stigmas. We used multivariable models to explore whether stigma experience was associated with awareness and usage of safer sex functions in dating apps among 7700 MSM who completed a 2019 US nationwide online survey. Perceived community intolerance of gay and bisexual men was associated with reduced awareness of sexual health strategy profile options (adjusted prevalence ratio [aPR] 0.95; 95% confidence interval [95% CI] 0.93-0.98) and sexual health information and resources (aPR 0.97; 95% CI 0.94-0.99). Stigma from family and friends was associated with increased usage of app-based sexual health reminders (aPR 1.14; 95% CI 1.02-1.28) and sexual health information and resources (aPR 1.16; 95% CI 1.04-1.31). Stigma experience of MSM should be considered in optimizing app-based sexual health interventions.
RESUMEN
In the United States, a context of multiple marginalization shapes sexual health disparities experienced by transgender women. Using data from 396 transgender women with negative or unknown HIV status, we performed exploratory factor analysis on responses to gender identity and sexual behavior stigma items and regressed sexual health outcomes on extracted factors via modified Poisson regression with robust variance estimation. Overall, 97.2% of participants endorsed ≥ 1 gender identity stigma; 67.2% endorsed ≥ 1 sexual behavior stigma; and 66.9% endorsed ≥ 1 of each. Extracted factors included gender-identity social stigma, reflecting experiences related to family, fearfulness in public, and verbal harassment (α = 0.68); gender-identity institutional stigma/violence, reflecting experiences related to healthcare, police interactions, and interpersonal violence (α = 0.73); and global sexual behavior stigma, reflecting experiences related to family, friends, and healthcare, as well as police interactions, fearfulness in public, verbal harassment, and interpersonal violence (α = 0.83). Gender-identity social stigma was significantly, positively associated with testing for HIV and testing for sexually transmitted infections. Gender-identity institutional stigma/violence and global sexual behavior stigma were both significantly, positively associated with condomless anal sex, sex work, testing for HIV, testing for sexually transmitted infections, and use of HIV pre-exposure prophylaxis. Stigma-mitigation remains critical to improve quality of life and sexual health for transgender women in the United States.

We analyzed data collected by the Encuesta de Sexo Entre Hombres study from 15,233 Mexican men who have sex with men (MSM) between May-July 2017 to examine differences in the HIV care continuum. Data were stratified into 6 geographical regions. Prevalence ratios assessed associations between region and care outcomes. Among participants never testing HIV positive (n = 13,583), 66.1% had ever been tested and 43.0% in the past year. Among HIV-positive persons (n = 1,650), 83.9% reported counseling post-diagnosis, 61.9% timely linkage to care, 42.4% timely CD4/viral load results, 38.2% timely access to antiretroviral therapy (ART), and 87.7% were currently on ART. The Ciudad de México /Estado de México region had significantly superior care continuum outcomes in ever and recent HIV testing, linkage to care, CD4/viral load results, and current ART use. Understanding geographical variations in HIV care for MSM in Mexico is one important step to inform efforts for ending HIV/AIDS by 2030 in Latin America.
RESUMEN: Analizamos los datos de 15,233 hombres mexicanos que tienen sexo con hombres (HSH) recopilados entre mayo y julio de 2017 por el estudio Encuesta de Sexo Entre Hombres para examinar las diferencias en el continuo de la atención del VIH. Los datos se estratificaron en seis regiones geográficas. Se utilizaron razones de prevalencia para evaluar las asociaciones entre la región y los resultados de la atención. Entre los participantes sin prueba de VIH positiva (n = 13 583), el 66.1% se había hecho la prueba alguna vez en su vida y el 43.0% en el último año. Entre las personas que refirieron pruebas de VIH positivas (n = 1 650), el 83.9% informó asesoramiento post-diagnóstico, el 61.9% vinculación oportuna a la atención, el 42.4% resultados oportunos de CD4/carga viral, el 38.2% acceso oportuno a la terapia antirretroviral (TAR) y el 87.7% continuaba en TAR. La región de la Ciudad de México/Estado de México tuvo resultados del continuo de la atención significativamente superiores en pruebas de VIH pasadas y recientes, vinculación con la atención, resultados de carga viral/CD4 y uso actual de TAR. Comprender las variaciones geográficas de la atención del VIH en HSH en México es un paso importante para informar los esfuerzos para poner fin a la epidemia de HIV/Sida para 2030 en Latinoamérica.

Little is known about the effect of travel-related factors, such as mode of transportation, on retention in PrEP care, or PrEP persistence. We used data from the 2020 American Men's Internet Survey and conducted multilevel logistic regression to estimate the association between mode of transportation used for healthcare access and PrEP persistence among urban gay, bisexual, and other men who have sex with men (MSM) in the U.S. MSM using public transportation were less likely to report PrEP persistence (aOR: 0.51; 95% CI: 0.28-0.95) than MSM using private transportation. There were no significant associations between PrEP persistence and using active transportation (aOR: 0.67; 95% CI: 0.35-1.29) or multimodal transportation (aOR: 0.85; 95% CI: 0.51-1.43) compared to using private transportation. Transportation-related interventions and policies are needed to address structural barriers to accessing PrEP services and to improve PrEP persistence in urban areas.

HIV prevention for gay, bisexual, and other men who have sex with men (GBMSM) and transgender women (TGW) is critical to reducing health disparities and population HIV prevalence. To understand if different types of stigma impact engagement with HIV prevention services, we assessed associations between stigmas and use of HIV prevention services offered through an HIV prevention intervention. This analysis included 201 GBMSM and TGW enrolled in a prospective cohort offering a package of HIV prevention interventions. Participants completed a baseline survey that included four domains of sexual identity/behavior stigma, HIV-related stigma, and healthcare stigma. Impact of stigma on PrEP uptake and the number of drop-in visits was assessed. No domain of stigma was associated with PrEP uptake. In bivariate analysis, increased enacted sexual identity stigma increased number of drop-in visits. In a logistic regression analysis constrained to sexual identity stigma, enacted stigma was associated with increased drop-in visits (aIRR = 1.30, [95% CI: 1.02, 1.65]). Participants reporting higher enacted stigma were modestly more likely to attend additional services and have contact with the study clinics and staff. GBMSM and TGW with higher levels of enacted stigma may seek out sensitized care after negative experiences in their communities or other healthcare settings.

Background: Chemsex is the intentional use of drugs to enhance sexual activity. Chemsex drug use among men who have sex with men (MSM) is associated with sexual behaviors that increase sexually transmitted infection (STI) risks and adverse mental health outcomes. However, published data are largely based on MSM recruited from STI clinics. There are limited data about use of chemsex drugs among national samples of MSM in the United States. Using data from the American Men's Internet Survey (AMIS), we assessed the prevalence and correlates of use of chemsex drugs among sexually active MSM in the United States. Methods: We used data from the 2017 to 2020 AMIS cycles to examine the prevalence of chemsex drug use in the past 12 months among MSM. We calculated prevalence ratios (PR) and 95% confidence intervals (CI) to compare chemsex drug use across demographic, behavioral, and mental health factors. Results: Of 30,294 MSM, 3,113 (10.3%) reported chemsex drug use in the past 12 months. Of the 3,113 MSM who reported chemsex drug use, 65.1% reported ecstasy use, 42.5% reported crystal methamphetamine use, and 21.7% reported GHB use. Factors associated with chemsex drug use included condomless anal sex (PR = 1.93, 95%=1.69-2.20), problem drinking (PR = 2.36, 95% = 2.13-2.61), bacterial STI test (1.84, 95% CI = 1.68-2.02) and probable serious mental illness (PR = 1.92, 95% = 1.76-2.09). Conclusion: Chemsex drug use is associated with behaviors that increase STI risk and mental distress among MSM. Health programs that serve MSM can consider screening for chemsex drug use and offering sexual and mental health promotion and risk reduction interventions when necessary.

BACKGROUND: Pre-exposure prophylaxis (PrEP) has not effectively reached black men who have sex with men (BMSM). Using innovative, nontraditional health care settings-such as community pharmacies-may improve PrEP uptake among BMSM. OBJECTIVE: To examine correlates of patient willingness to be screened for PrEP (via human immunodeficiency virus [HIV] testing and risk assessment) in pharmacies among BMSM in the United States. METHODS: Data from the 2020 American Men's Internet Survey were analyzed. Using a modified Poisson regression method with robust variance estimates, we examined differences in willingness to screen for PrEP in pharmacies among BMSM. A 95% confidence interval (95% CI) was calculated for each estimated prevalence ratio (PR). RESULTS: Of 826 respondents, 637 (77%) were willing to be screened for PrEP in pharmacies. Having a high school degree (PR 0.76 [95% CI 0.62-0.95]), willingness to use PrEP (1.70 [1.41-2.05]), and comfort speaking with pharmacy staff about PrEP (2.5 [1.86-3.51]) were significantly associated with willingness to screen for PrEP in a pharmacy setting. Importantly, there were no observed differences in willingness by age, employment status, annual household income, or insurance status. CONCLUSION: Pharmacy-based PrEP access may be an effective strategy to end inequities in HIV, given that our results indicate that most BMSM are willing to be screened for PrEP in pharmacies. Future studies should examine whether willingness to use pharmacy-based HIV prevention services is associated with subsequent uptake of these services among BMSM.

BACKGROUND: Reported coronavirus disease 2019 (COVID-19) cases underestimate true severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. Data on all infections, including asymptomatic infections, are needed. To minimize biases in estimates from reported cases and seroprevalence surveys, we conducted a household-based probability survey and estimated cumulative incidence of SARS-CoV-2 infections adjusted for antibody waning. METHODS: From August to December 2020, we mailed specimen collection kits (nasal swabs and blood spots) to a random sample of Georgia addresses. One household adult completed a survey and returned specimens for virus and antibody testing. We estimated cumulative incidence of SARS-CoV-2 infections adjusted for waning antibodies, reported fraction, and infection fatality ratio (IFR). Differences in seropositivity among demographic, geographic, and clinical subgroups were explored with weighted prevalence ratios (PR). RESULTS: Among 1370 participants, adjusted cumulative incidence of SARS-CoV-2 was 16.1% (95% credible interval [CrI], 13.5%-19.2%) as of 16 November 2020. The reported fraction was 26.6% and IFR was 0.78%. Non-Hispanic black (PR, 2.03; 95% confidence interval [CI], 1.0-4.1) and Hispanic adults (PR, 1.98; 95% CI, .74-5.31) were more likely than non-Hispanic white adults to be seropositive. CONCLUSIONS: As of mid-November 2020, 1 in 6 adults in Georgia had been infected with SARS-CoV-2. The COVID-19 epidemic in Georgia is likely substantially underestimated by reported cases.

BACKGROUND: Reported coronavirus disease 2019 (COVID-19) cases underestimate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. We conducted a national probability survey of US households to estimate cumulative incidence adjusted for antibody waning. METHODS: From August-December 2020 a random sample of US addresses were mailed a survey and self-collected nasal swabs and dried blood spot cards. One adult household member completed the survey and mail specimens for viral detection and total (immunoglobulin [Ig] A, IgM, IgG) nucleocapsid antibody by a commercial, emergency use authorization-approved antigen capture assay. We estimated cumulative incidence of SARS-CoV-2 adjusted for waning antibodies and calculated reported fraction (RF) and infection fatality ratio (IFR). Differences in seropositivity among demographic, geographic, and clinical subgroups were explored. RESULTS: Among 39 500 sampled households, 4654 respondents provided responses. Cumulative incidence adjusted for waning was 11.9% (95% credible interval [CrI], 10.5%-13.5%) as of 30 October 2020. We estimated 30 332 842 (CrI, 26 703 753-34 335 338) total infections in the US adult population by 30 October 2020. RF was 22.3% and IFR was 0.85% among adults. Black non-Hispanics (Prevalence ratio (PR) 2.2) and Hispanics (PR, 3.1) were more likely than White non-Hispanics to be seropositive. CONCLUSIONS: One in 8 US adults had been infected with SARS-CoV-2 by October 2020; however, few had been accounted for in public health reporting. The COVID-19 pandemic is likely substantially underestimated by reported cases. Disparities in COVID-19 by race observed among reported cases cannot be attributed to differential diagnosis or reporting of infections in population subgroups.

BACKGROUND: Population-level estimates of sexual network mixing for parameterizing prediction models of pre-exposure prophylaxis (PrEP) effectiveness are needed to inform prevention of HIV transmission among men who have sex with men (MSM). Estimates obtained by egocentric sampling are vulnerable to information bias due to incomplete respondent knowledge. METHODS: We estimated patterns of serosorting and PrEP sorting among MSM in the United States using data from a 2017-2019 egocentric sexual network study. Respondents served as proxies to report the HIV status and PrEP use of recent sexual partners. We contrasted results from a complete-case analysis (unknown HIV and PrEP excluded) versus a bias analysis with respondent-reported data stochastically reclassified to simulate unobserved self-reported data from sexual partners. RESULTS: We found strong evidence of preferential partnering across analytical approaches. The bias analysis showed concordance between sexual partners of HIV diagnosis and PrEP use statuses for MSM with diagnosed HIV (39%; 95% simulation interval: 31, 46), MSM who used PrEP (32%; 21, 37), and MSM who did not use PrEP (83%; 79, 87). The fraction of partners with diagnosed HIV was higher among MSM who used PrEP (11%; 9, 14) compared with MSM who did not use PrEP (4%; 3, 5). Comparatively, across all strata of respondents, the complete-case analysis overestimated the fractions of partners with diagnosed HIV or PrEP use. CONCLUSIONS: We found evidence consistent with HIV and PrEP sorting among MSM, which may decrease the population-level effectiveness of PrEP. Bias analyses can improve mixing estimates for parameterization of transmission models.

BACKGROUND: Prospects for a gonococcal vaccine have advanced. Vaccine acceptability is crucial to maximizing population-level protection among key groups, such as men who have sex with men (MSM). We assessed the prevalence of gonococcal vaccine acceptability among sexually active MSM in the United States. METHODS: We used data from the American Men's Internet Study conducted from August 2019 to December 2019. We calculated frequencies of sociodemographic characteristics, vaccine acceptability, and preferred location for vaccine receipt. Using log-binomial regression analyses, we calculated unadjusted prevalence rates (PRs) and 95% confidence intervals (CIs) to evaluate factors associated with vaccine acceptability. RESULTS: Of 4951 MSM, 83.5% were willing to accept a vaccine and 16.5% were unwilling. Preferred vaccination locations were primary care provider's clinics (83.5%) and sexually transmitted disease (STD) clinics (64.6%). Vaccine acceptability was greater among young MSM (15-24 years [PR, 1.09; 95% CI, 1.05-1.12], 25-29 years [PR, 1.13; 95% CI, 1.09-1.17], and 30-39 years [PR, 1.10; 95% CI, 1.05-1.14] compared with MSM ≥40 years), MSM living with HIV (PR, 1.05; 95% CI, 1.02-1.09), and MSM who reported (in the past 12 months) condomless anal sex (PR, 1.09; 95% CI, 1.06-1.12), a bacterial STD test (PR, 1.18; 95% CI, 1.15-1.21), HIV preexposure prophylaxis use (PR, 1.17; 95% CI, 1.14-1.19), a bacterial STD diagnosis (PR, 1.04; 95% CI, 1.02-1.07), or a health care provider visit (PR, 1.11; 95% CI, 1.06-1.16). Men who have sex with men who reported ≤high school education (PR, 0.93; 95% CI, 0.91-0.97) were less willing to accept a vaccine compared with those with >high school education. CONCLUSIONS: Most respondents were willing to accept a gonococcal vaccine. These findings can inform the planning and implementation of a future gonococcal vaccination program that focuses on MSM.
