RESUMO
BACKGROUND AND AIMS: The National Health and Nutrition Examination Survey (NHANES) underestimates the true prevalence of HCV infection. By accounting for populations inadequately represented in NHANES, we created 2 models to estimate the national hepatitis C prevalence among US adults during 2017-2020. APPROACH AND RESULTS: The first approach (NHANES+) replicated previous methodology by supplementing hepatitis C prevalence estimates among the US noninstitutionalized civilian population with a literature review and meta-analysis of hepatitis C prevalence among populations not included in the NHANES sampling frame. In the second approach (persons who injected drugs [PWID] adjustment), we developed a model to account for the underrepresentation of PWID in NHANES by incorporating the estimated number of adult PWID in the United States and applying PWID-specific hepatitis C prevalence estimates. Using the NHANES+ model, we estimated HCV RNA prevalence of 1.0% (95% CI: 0.5%-1.4%) among US adults in 2017-2020, corresponding to 2,463,700 (95% CI: 1,321,700-3,629,400) current HCV infections. Using the PWID adjustment model, we estimated HCV RNA prevalence of 1.6% (95% CI: 0.9%-2.2%), corresponding to 4,043,200 (95% CI: 2,401,800-5,607,100) current HCV infections. CONCLUSIONS: Despite years of an effective cure, the estimated prevalence of hepatitis C in 2017-2020 remains unchanged from 2013 to 2016 when using a comparable methodology. When accounting for increased injection drug use, the estimated prevalence of hepatitis C is substantially higher than previously reported. National action is urgently needed to expand testing, increase access to treatment, and improve surveillance, especially among medically underserved populations, to support hepatitis C elimination goals.
RESUMO
BACKGROUND: Public health data signal increases in the number of people who inject drugs (PWID) in the United States during the past decade. An updated PWID population size estimate is critical for informing interventions and policies aiming to reduce injection-associated infections and overdose, as well as to provide a baseline for assessments of pandemic-related changes in injection drug use. METHODS: We used a modified multiplier approach to estimate the number of adults who injected drugs in the United States in 2018. We deduced the estimated number of nonfatal overdose events among PWID from 2 of our previously published estimates: the number of injection-involved overdose deaths and the meta-analyzed ratio of nonfatal to fatal overdose. The number of nonfatal overdose events was divided by prevalence of nonfatal overdose among current PWID for a population size estimate. RESULTS: There were an estimated 3 694 500 (95% confidence interval [CI], 1 872 700-7 273 300) PWID in the United States in 2018, representing 1.46% (95% CI, .74-2.87) of the adult population. The estimated prevalence of injection drug use was highest among males (2.1%; 95% CI, 1.1-4.2), non-Hispanic Whites (1.8%; 95% CI, .9-3.6), and adults aged 18-39 years (1.8%; 95% CI, .9-3.6). CONCLUSIONS: Using transparent, replicable methods and largely publicly available data, we provide the first update to the number of people who inject drugs in the United States in nearly 10 years. Findings suggest the population size of PWID has substantially grown in the past decade and that prevention services for PWID should be proportionally increased.

People who inject drugs (PWID) with unsafe injection practices have substantial risk for HIV and hepatitis C virus (HCV) infections. We describe frequency of, and factors associated with, HIV and HCV testing during clinical encounters with PWID. Inpatient and Emergency Department clinical encounters at an Atlanta hospital were abstracted from medical records spanning January 2013-December 2018. We estimated frequency of HIV and HCV testing during injection drug use (IDU)-related encounters among PWID without previous diagnoses. We assessed associations between patient factors and testing using generalized estimating equations models. HIV testing occurred in 39.3% and HCV testing occurred in 17.1% of eligible IDU-related encounters. Testing was more likely in IDU-related encounters during 2017-2018 than in encounters during 2013-2014; (HIV, AOR = 2.14, 95% CI, 1.32-3.49, p < .01). Testing was less likely among Black/African American patients compared to White patients (adjusted odds ratio [AOR]: HIV, AOR = 0.48, 95% confidence interval [CI], 0.33-0.72, p < .01); HCV, AOR = 0.41, 95% CI, 0.24-0.70, p < .01). This difference may be attributable to recent testing among Black patients in non-IDU related encounters. HIV and HCV testing improved over time; however, missed opportunities for testing still existed. Strategies should aim to improve equitable HIV and HCV testing among PWID.

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.

BACKGROUND: The COVID-19 pandemic continues to have high caseloads in the US, with vaccines a critical component of the response. Disparities in COVID-19 morbidity and mortality have been identified across states and racial/ethnic groups, which are likely in part due to disparities in COVID-19 vaccine uptake. This study aims to better understand and contextualize COVID-19 vaccine hesitancy among persons from under-represented racial/ethnic populations in the Southern US. METHODS: We conducted 29 in-depth interviews with a sample of households in Atlanta, GA that were selected from an address-based sampling frame. We purposively approached households, from February 6 to June 27, 2021, that declined participation in a national COVID-19 serosurvey to gain perspectives of people who are often under-represented in research. Interviews were conducted in-person or over phone calls for participants with that preference. Thematic analysis was used to identify barriers and facilitators of COVID-19 vaccination, and to contextualize drivers of vaccine hesitancy. RESULTS: Decision-making about vaccination was described as dynamic, and was compared to the feeling of being on a roller coaster. The predominant reported sources of information were mass media and social media. Facilitators of vaccination included altruism, positive communication from trusted community members and workplace colleagues, and local vaccine provision sites. Driving reasons for vaccine hesitancy included limited trust in the government and concerns about COVID-19 vaccine safety, which one participant compared to jumping off a cliff without a tested rope. Among a subset of participants, beliefs regarding perceived intent to harm the Black community were prevalent. Opportunities to optimally address vaccine hesitancy included countering negative social media messages with positive messaging that matches the community's vivid ways of discussing vaccines, collaborating with community stakeholders on vaccine promotion efforts, and offering workplace-based vaccine promotion efforts. CONCLUSIONS: This study presents data that indicate it may be optimal to more broadly define 'community' in COVID-19 vaccine promotion efforts to include social media and workplace venues. To optimize vaccine and vaccine booster uptake and equity, public health must address historic racism and other concerns by using outreach that is grounded in communities.

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: Although effective against hepatitis B virus (HBV) infection, hepatitis B (HepB) vaccination is only recommended for infants, children, and adults at higher risk. We conducted an economic evaluation of universal HepB vaccination among US adults. METHODS: Using a decision analytic model with Markov disease progression, we compared current vaccination recommendations (baseline) with either 3-dose or 2-dose universal HepB vaccination (intervention strategies). In simulated modeling of 1 million adults distributed by age and risk groups, we quantified health benefits (quality-adjusted life years, QALYs) and costs for each strategy. Multivariable probabilistic sensitivity analyses identified key inputs. All costs reported in 2019 US dollars. RESULTS: With incremental base-case vaccination coverage up to 50% among persons at lower risk and 0% increment among persons at higher risk, each of 2 intervention strategies averted nearly one-quarter of acute HBV infections (3-dose strategy, 24.8%; 2-dose strategy, 24.6%). Societal incremental cost per QALY gained of $152 722 (interquartile range, $119 113-$235 086) and $155 429 (interquartile range, $120 302-$242 226) were estimated for 3-dose and 2-dose strategies, respectively. Risk of acute HBV infection showed the strongest influence. CONCLUSIONS: Universal adult vaccination against HBV may be an appropriate strategy for reducing HBV incidence and improving resulting health outcomes.

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.

The HIV epidemic in the USA began as a bicoastal epidemic focused in large cities but, over nearly four decades, the epidemiology of HIV has changed. Public health surveillance data can inform an understanding of the evolution of the HIV epidemic in terms of the populations and geographical areas most affected. We analysed publicly available HIV surveillance data and census data to describe: current HIV prevalence and new HIV diagnoses by region, race or ethnicity, and age; trends in HIV diagnoses over time by HIV acquisition risk and age; and the distribution of HIV prevalence by geographical area. We reviewed published literature to explore the reasons for the current distribution of HIV cases and important disparities in HIV prevalence. We identified opportunities to improve public health surveillance systems and uses of data for planning and monitoring public health responses. The current US HIV epidemic is marked by geographical concentration in the US South and profound disparities between regions and by race or ethnicity. Rural areas vary in HIV prevalence; rural areas in the South are more likely to have a high HIV prevalence than rural areas in other US Census regions. Ongoing disparities in HIV in the South are probably driven by the restricted expansion of Medicaid, health-care provider shortages, low health literacy, and HIV stigma. HIV diagnoses overall declined in 2009-18, but HIV diagnoses among individuals aged 25-34 years increased during the same period. HIV diagnoses decreased for all risk groups in 2009-18; among men who have sex with men (MSM), new diagnoses decreased overall and for White MSM, remained stable for Black MSM, and increased for Hispanic or Latino MSM. Surveillance data indicate profound and ongoing disparities in HIV cases, with disproportionate impact among people in the South, racial or ethnic minorities, and MSM.

BACKGROUND AND AIMS: Since 2013, the national hepatitis C virus (HCV) death rate has steadily declined, but this decline has not been quantified or described on a local level. APPROACH AND RESULTS: We estimated county-level HCV death rates and assessed trends in HCV mortality from 2005 to 2013 and from 2013 to 2017. We used mortality data from the National Vital Statistics System and used a Bayesian multivariate space-time conditional autoregressive model to estimate age-standardized HCV death rates from 2005 through 2017 for 3,115 U.S. counties. Additionally, we estimated county-level, age-standardized rates for persons <40 and 40+ years of age. We used log-linear regression models to estimate the average annual percent change in HCV mortality during periods of interest and compared county-level trends with national trends. Nationally, the age-adjusted HCV death rate peaked in 2013 at 5.20 HCV deaths per 100,000 persons (95% credible interval [CI], 5.12, 5.26) before decreasing to 4.34 per 100,000 persons (95% CI, 4.28, 4.41) in 2017 (average annual percent change = -4.69; 95% CI, -5.01, -4.33). County-level rates revealed heterogeneity in HCV mortality (2017 median rate = 3.6; interdecile range, 2.19, 6.77), with the highest rates being concentrated in the West, Southwest, Appalachia, and northern Florida. Between 2013 and 2017, HCV mortality decreased in 80.0% (n = 2,274) of all U.S. counties with a reliable trend estimate, with 25.8% (n = 803) of all counties experiencing a decrease larger than the national decline. CONCLUSIONS: Although many counties have experienced a shift in HCV mortality trends since 2013, the magnitude and composition of that shift have varied by place. These data provide a better understanding of geographic differences in HCV mortality and can be used by local jurisdictions to evaluate HCV mortality in their areas relative to surrounding areas and the nation.

BACKGROUND: In the United States, injection is an increasingly common route of administration for opioids and other substances. Estimates of the number of persons who inject drugs (PWID) are needed for monitoring risk-specific infectious disease rates and health services coverage. METHODS: We reviewed design and instruments for 4 national household surveys, 2012-2016, for their ability to produce unbiased injection drug use (IDU) prevalence estimates. We explored potential analytic adjustments for reducing biases through use of external data on (1) arrest, (2) narcotic overdose mortality, and (3) biomarker-based sensitivity of self-reported illicit drug use. RESULTS: Estimated national past 12 months IDU prevalence ranged from 0.24% to 0.59% across surveys. All surveys excluded unstably housed and incarcerated persons, and estimates were based on <60 respondents reporting IDU behavior in 3 surveys. No surveys asked participants about nonmedical injection of prescription drugs. Analytic adjustments did not appreciably change IDU prevalence estimates due to suboptimal specificity of data points. CONCLUSIONS: PWID population size estimates in the United States are based on small numbers and are likely biased by undercoverage of key populations and self-report. Novel methods as discussed in this article may improve our understanding of PWID population size and their health needs.

In 2016, more than 90% of HIV diagnoses among young men aged 13-19 years were attributed to male-male sexual contact. Little is known about how binge drinking and non-injection drug use may be associated with risky sexual behavior among adolescent sexual minority males (ASMM). Using data from the National HIV Behavioral Surveillance, we examined how binge drinking and non-injection drug use may be associated with sexual risk among ASMM. ASMM were recruited for interviews in 3 cities: Chicago, New York City, and Philadelphia. Among 16-18-year-olds (N = 488), we evaluated the association between binge drinking (≥ 5 drinks in one sitting in the past 30 days), non-injection drug use (past 12-month use of methamphetamines, powder cocaine, downers, painkillers, ecstasy, poppers, and "other"), and two past 12-month sexual risk outcomes: condomless anal intercourse with a casual partner and having multiple sex partners. We used log-linked Poisson regression models with robust standard errors to estimate prevalence ratios (PR) and 95% confidence intervals (CI). Overall, 26% of 16-18-year-old ASMM binge drank, and 21% reported non-injection drug use. Among ASMM who binge drank, 34% reported condomless anal intercourse with a casual partner compared with 22% of those who did not (PR: 1.53, 95% CI: 1.04-2.26). Similarly, 84% of ASMM who binge drank reported having multiple partners compared with 61% of those who did not (PR: 1.38, 95% CI: 1.09-1.76). Among ASMM who used non-injection drugs, 37% reported condomless anal intercourse compared with 22% of those who did not (PR: 1.70, 95% CI 1.09-2.50), while 86% of those who used non-injection drugs had multiple partners compared with 62% of those who did not (PR: 1.40, 95% CI: 1.06-1.80). Our findings suggest that the prevalence of substance misuse is high among sexual minority youth and is associated with sexual risk in this population. Our findings highlight the need for high-quality HIV prevention programs for ASMM especially as HIV prevention programs for this population are scarce.

BACKGROUND: Innovative laboratory testing approaches for SARS-CoV-2 infection and immune response are needed to conduct research to establish estimates of prevalence and incidence. Self-specimen collection methods have been successfully used in HIV and sexually transmitted infection research and can provide a feasible opportunity to scale up SARS-CoV-2 testing for research purposes. OBJECTIVE: The aim of this study was to assess the willingness of adults to use different specimen collection modalities for themselves and children as part of a COVID-19 research study. METHODS: Between March 27 and April 1, 2020, we recruited 1435 adults aged 18 years or older though social media advertisements. Participants completed a survey that included 5-point Likert scale items stating how willing they were to use the following specimen collection testing modalities as part of a research study: home collection of a saliva sample, home collection of a throat swab, home finger-prick blood collection, drive-through site throat swab, clinic throat swab, and clinic blood collection. Additionally, participants indicated how the availability of home-based collection methods would impact their willingness to participate compared to drive-through and clinic-based specimen collection. We used Kruskal-Wallis tests and Spearman rank correlations to assess if willingness to use each testing modality differed by demographic variables and characteristics of interest. We compared the overall willingness to use each testing modality and estimated effect sizes with Cohen d. RESULTS: We analyzed responses from 1435 participants with a median age of 40.0 (SD=18.2) years and over half of which were female (761/1435, 53.0%). Most participants agreed or strongly agreed that they would be willing to use specimens self-collected at home to participate in research, including willingness to collect a saliva sample (1259/1435, 87.7%) or a throat swab (1191/1435, 83.1%). Willingness to collect a throat swab sample was lower in both a drive-through setting (64%) and clinic setting (53%). Overall, 69.0% (990/1435) of participants said they would be more likely to participate in a research study if they could provide a saliva sample or throat swab at home compared to going to a drive-through site; only 4.4% (63/1435) of participants said they would be less likely to participate using self-collected samples. For each specimen collection modality, willingness to collect specimens from children for research was lower than willingness to use on oneself, but the ranked order of modalities was similar. CONCLUSIONS: Most participants were willing to participate in a COVID-19 research study that involves laboratory testing; however, there was a strong preference for home specimen collection procedures over drive-through or clinic-based testing. To increase participation and minimize bias, epidemiologic research studies of SARS-CoV-2 infection and immune response should consider home specimen collection methods.

BACKGROUND: Existing health disparities based on race and ethnicity in the United States are contributing to disparities in morbidity and mortality during the coronavirus disease (COVID-19) pandemic. We conducted an online survey of American adults to assess similarities and differences by race and ethnicity with respect to COVID-19 symptoms, estimates of the extent of the pandemic, knowledge of control measures, and stigma. OBJECTIVE: The aim of this study was to describe similarities and differences in COVID-19 symptoms, knowledge, and beliefs by race and ethnicity among adults in the United States. METHODS: We conducted a cross-sectional survey from March 27, 2020 through April 1, 2020. Participants were recruited on social media platforms and completed the survey on a secure web-based survey platform. We used chi-square tests to compare characteristics related to COVID-19 by race and ethnicity. Statistical tests were corrected using the Holm Bonferroni correction to account for multiple comparisons. RESULTS: A total of 1435 participants completed the survey; 52 (3.6%) were Asian, 158 (11.0%) were non-Hispanic Black, 548 (38.2%) were Hispanic, 587 (40.9%) were non-Hispanic White, and 90 (6.3%) identified as other or multiple races. Only one symptom (sore throat) was found to be different based on race and ethnicity (P=.003); this symptom was less frequently reported by Asian (3/52, 5.8%), non-Hispanic Black (9/158, 5.7%), and other/multiple race (8/90, 8.9%) participants compared to those who were Hispanic (99/548, 18.1%) or non-Hispanic White (95/587, 16.2%). Non-Hispanic White and Asian participants were more likely to estimate that the number of current cases was at least 100,000 (P=.004) and were more likely to answer all 14 COVID-19 knowledge scale questions correctly (Asian participants, 13/52, 25.0%; non-Hispanic White participants, 180/587, 30.7%) compared to Hispanic (108/548, 19.7%) and non-Hispanic Black (25/158, 15.8%) participants. CONCLUSIONS: We observed differences with respect to knowledge of appropriate methods to prevent infection by the novel coronavirus that causes COVID-19. Deficits in knowledge of proper control methods may further exacerbate existing race/ethnicity disparities. Additional research is needed to identify trusted sources of information in Hispanic and non-Hispanic Black communities and create effective messaging to disseminate correct COVID-19 prevention and treatment information.

BACKGROUND: AIDSVu is a public resource for visualizing HIV surveillance data and other population-based information relevant to HIV prevention, care, policy, and impact assessment. OBJECTIVE: The site, AIDSVu.org, aims to make data about the US HIV epidemic widely available, easily accessible, and locally relevant to inform public health decision making. METHODS: AIDSVu develops visualizations, maps, and downloadable datasets using results from HIV surveillance systems, other population-based sources of information (eg, US Census and national probability surveys), and other data developed specifically for display and dissemination through the website (eg, pre-exposure prophylaxis [PrEP] prescriptions). Other types of content are developed to translate surveillance data into summarized content for diverse audiences using infographic panels, interactive maps, local and state fact sheets, and narrative blog posts. RESULTS: Over 10 years, AIDSVu.org has used an expanded number of data sources and has progressively provided HIV surveillance and related data at finer geographic levels, with current data resources providing HIV prevalence data down to the census tract level in many of the largest US cities. Data are available at the county level in 48 US states and at the ZIP Code level in more than 50 US cities. In 2019, over 500,000 unique users consumed AIDSVu data and resources, and HIV-related data and insights were disseminated through nearly 4,000,000 social media posts. Since AIDSVu's inception, at least 249 peer-reviewed publications have used AIDSVu data for analyses or referenced AIDSVu resources. Data uses have included targeting of HIV testing programs, identifying areas with inequitable PrEP uptake, including maps and data in academic and community grant applications, and strategically selecting locations for new HIV treatment and care facilities to serve high-need areas. CONCLUSIONS: Surveillance data should be actively used to guide and evaluate public health programs; AIDSVu translates high-quality, population-based data about the US HIV epidemic and makes that information available in formats that are not consistently available in surveillance reports. Bringing public health surveillance data to an online resource is a democratization of data, and presenting information about the HIV epidemic in more visual formats allows diverse stakeholders to engage with, understand, and use these important public health data to inform public health decision making.

BACKGROUND: Guidelines recommend that sexually active men who have sex with men (MSM) including human immunodeficiency virus (HIV)-positive MSM be tested at least annually for syphilis, with testing every 3-6 months for MSM at elevated risk. We examined the proportion of HIV-positive MSM tested for syphilis in the past 3, 6, and 12 months by their HIV care provider during 2013-2014. METHODS: Using data from the Medical Monitoring Project, a population-based HIV surveillance system, we evaluated the proportion of MSM who had documentation of being tested for syphilis by their HIV care provider in the past 3, 6, and 12 months. RESULTS: During 2013-2014, 71% (95% confidence interval [CI]: 69%-73%) of sexually active HIV-positive MSM were tested for syphilis in the past year. This proportion was higher among MSM reporting condomless sex: (75%; 95% CI: 72%-78%), and among MSM reporting ≥ 2 sex partners (77%; 95% CI: 74%-79%), in the past 12 months. Among MSM reporting condomless sex, 49% (95% CI: 45%-53%) were tested in the past 6 months, and 26% (95% CI: 22%-30%) in the past 3 months. Among MSM reporting ≥ 2 sex partners, 49% (95% CI: 44%-54%) were tested in the past 6 months and 26% (95% CI: 22%-29%) in the past 3 months. CONCLUSIONS: Nearly one-third of sexually active HIV-positive MSM were not tested annually, and many at increased risk were not tested at recommended frequencies. Efforts to improve compliance with screening guidelines for high-risk HIV-positive MSM are warranted.

The rate of diagnosis of human immunodeficiency virus (HIV) infection among American Indians and Alaska Natives (AI/ANs) in 2016 (10.2 per 100,000 population) was the fourth highest among seven racial/ethnic groups in the United States (1); the number of diagnoses of HIV infection among AI/AN persons increased by 70%, from 143 in 2011 to 243 in 2016 (1). However, little has been published about the sociodemographic, behavioral, and clinical characteristics of AI/AN patients with HIV infection in care because small sample sizes have led to infrequent analysis of AI/AN-specific estimates (2) and because of underestimation of AI/AN race/ethnicity in surveillance and other data sources (3). CDC analyzed data from the Medical Monitoring Project (MMP), a surveillance system that collects information about the experiences and needs of persons with diagnosed HIV infection, collected during 2011-2015 among AI/AN adults receiving HIV medical care. The results indicated that 64% of AI/AN patients with HIV infection in care achieved sustained viral suppression, and 76% achieved viral suppression at their most recent viral load test within the past 12 months, which is below the national HIV prevention goal of 80%, but comparable to or better than some other racial/ethnic groups (4). Based on self-report, 51% of AI/AN patients with HIV infection had incomes at or below the U.S. Department of Health and Human Services' (HHS) annual poverty limit, 27% had symptoms of depression, 78% reported internalized HIV-related stigma, and 20% reported binge drinking in the past 30 days. To improve the health of AI/AN patients with HIV infection, it is important that health care providers, tribal organizations, and state and local health departments consider the sociodemographic and behavioral barriers to AI/AN patients with HIV infection achieving viral suppression and design care plans that seek to eliminate those barriers.

Progress in reducing HIV infections has been suboptimal despite availability of effective prevention and treatment interventions and national strategies to bring them to scale. As part of a community-driven process, we expanded previous epidemiologic models using updated surveillance data from the Centers for Disease Control and Prevention to estimate quantitative parameters for ambitious but attainable national HIV prevention goals. We estimated new HIV infections could be reduced by up to 67% and prevalence could begin to decline by 2030 if 95% targets for diagnosis, care retention, and viral suppression are met by 2025 and an additional 20% of transmissions are averted through targeted interventions such as pre-exposure prophylaxis. Notably, this would require the percentage of diagnosed persons retained in HIV care to increase by more than 35 percentage points, which would necessitate innovative models and a substantial expansion of supportive services. Although the HIV incidence reduction goal of 90% as unveiled in the 2019 State of the Union Address is likely unachievable with the current intervention toolkit, it is possible to begin to substantially reduce HIV prevalence in the next decade with sufficient investments and innovation.

Previous research indicates a high burden of depression among adults living with HIV and an association between depression and poor HIV clinical outcomes. National estimates of diagnosed depression, depression treatment status, and association with HIV clinical outcomes are lacking. We used 2009-2014 data from the Medical Monitoring Project to estimate diagnosed depression, antidepressant treatment status, and associations with sustained viral suppression (all viral loads in past year < 200 copies/mL). Data were obtained through interview and medical record abstraction and were weighted to account for unequal selection probabilities and non-response. Of adults receiving HIV medical care in the U.S. and prescribed ART, 27% (95% confidence interval [CI] 25-29%) had diagnosed depression during the surveillance period; the majority (65%) were prescribed antidepressants. The percentage with sustained viral suppression was highest among those without depression (72%, CI 71-73%) and lowest among those with untreated depression (66%, CI 64-69%). Compared to those without depression, those with a depression diagnosis were less likely to achieve sustained viral suppression (aPR 0.95, CI 0.93-0.97); this association held for persons with treated depression compared to no depression (aPR 0.96, CI 0.94-0.99) and untreated depression compared to no depression (aPR 0.92, CI 0.89-0.96). The burden of depression among adults living with HIV in care is high. While in our study depression was only minimally associated with a lower prevalence of sustained viral suppression, diagnosing and treating depression in persons living with HIV remains crucial in order to improve mental health and avoid other poor health outcomes.

Background: Persons with HIV infection are at increased risk for hepatitis B virus infection. In 2016, the World Health Organization resolved to eliminate hepatitis B as a public health threat by 2030. Objective: To estimate the prevalence of hepatitis B vaccination among U.S. patients receiving medical care for HIV infection ("HIV patients"). Design: Nationally representative cross-sectional survey. Setting: United States. Participants: 18 089 adults receiving HIV medical care who participated in the Medical Monitoring Project during 2009 to 2012. Measurements: Primary outcomes were prevalence of 1) no documentation of hepatitis B vaccination or laboratory evidence of immunity or infection (candidates to initiate vaccination), and 2) initiation of vaccination among candidates, defined as documentation of at least 1 vaccine dose in a 1-year surveillance period during which patients received ongoing HIV medical care. Results: At the beginning of the surveillance period, 44.2% (95% CI, 42.2% to 46.2%) of U.S. HIV patients were candidates to initiate vaccination. By the end of the surveillance period, 9.6% (CI, 8.4% to 10.8%) of candidates were vaccinated, 7.5% (CI, 6.4% to 8.6%) had no documented vaccination but had documented infection or immunity, and 82.9% (CI, 81.1% to 84.7%) remained candidates. Among patients at facilities funded by the Ryan White HIV/AIDS Program (RWHAP), 12.5% (CI, 11.1% to 13.9%) were vaccinated during the surveillance period versus 3.7% (CI, 2.6% to 4.7%) at facilities not funded by RWHAP. At the end of surveillance, 36.7% (CI, 34.4% to 38.9%) of HIV patients were candidates to initiate vaccination. Limitation: The study was not designed to describe vaccine series completion or actual prevalence of immunity. Conclusion: More than one third of U.S. HIV patients had missed opportunities to initiate hepatitis B vaccination. Meeting goals for hepatitis B elimination will require increased vaccination of HIV patients in all practice settings, particularly at facilities not funded by RWHAP. Primary Funding Source: Centers for Disease Control and Prevention.
