BACKGROUND: Medications for opioid use disorder (MOUD) are key to preventing opioid overdose. Despite the high risk of opioid overdose among recently incarcerated people who use drugs, missed opportunities for engagement in MOUD treatment persist in this population. We examined the association between unmet need for MOUD and non-fatal opioid overdose among recently incarcerated people who inject drugs (PWID) and assessed prevalence of non-fatal opioid overdose by selected characteristics. METHODS: We analyzed 2022 data from the National HIV Behavioral Surveillance (NHBS) system among PWID from 20 large U.S. cities. Adjusted prevalence ratios (aPR) and 95 % confidence intervals (95 % CI) were calculated to examine the association between unmet need for MOUD and non-fatal opioid overdose. RESULTS: Among 1648 recently incarcerated PWID, 28 % reported an unmet need for MOUD and 39 % reported a non-fatal opioid-involved overdose in the past 12 months. Experiencing homelessness in the last 12 months (aPR=1.43, 95 % CI=1.27-1.61) and living in the Midwest region of the U.S. (aPR=1.18, 95 % CI=1.01-1.38) were significantly associated with reporting a non-fatal opioid overdose. Recently incarcerated PWID with an unmet need for MOUD were 1.4 times as likely to report a non-fatal opioid overdose in the past 12 months (50 %; aPR=1.42, 95 % CI=1.29-1.56) compared with recently incarcerated PWID without an unmet need for MOUD (35 %). CONCLUSIONS: Unmet need for MOUD was significantly associated with non-fatal opioid overdose among PWID who were incarcerated in the past 12 months, suggesting the need to investigate specific strategies to improve to MOUD treatment among recently incarcerated PWID.

BACKGROUND: Men who inject drugs who have sex with men (MWIDSM) may acquire HIV through injecting drugs or sex. Interventions to increase awareness of HIV preexposure prophylaxis (PrEP) have focused on gay/bisexual MSM and may not be reaching heterosexual-identifying men or people who inject drugs (PWID). We explored changes in PrEP awareness and use among MWIDSM from 2018 to 2022 by sexual identity. METHODS: We used data from the 2018 and 2022 National HIV Behavioral Surveillance among PWID recruited via respondent-driven sampling in 19 urban areas in the US. We examined changes in PrEP awareness and use over time by sexual identity among HIV-negative men who inject drugs and who had sex with another man in the past 12 months using log-linked Poisson regression models with robust standard errors with an interaction term between year and sexual identity. RESULTS: Among 758 HIV-negative MWIDSM (463 in 2018; 295 in 2022), nearly all sample participants were likely indicated for PrEP (94.2 and 92.9%, respectively). PrEP awareness increased from 2018 to 2022 among gay/bisexual-identifying MWIDSM [45.5-65.5%; aPR = 1.49, 95% confidence interval (95% CI) = 1.30-1.70] but remained stable for heterosexual-identifying MWIDSM (39.4-40.8%; aPR = 1.01, 95% CI 0.75-1.36). PrEP use remained low among all MWIDSM (2.5-7.7%, among heterosexually identifying; 15.3 to 10.2% among gay/bisexual-identifying). CONCLUSION: PrEP awareness increased among gay/bisexual-identifying MWIDSM but not among heterosexual-identifying. PrEP use was low for all MWIDSM. Public health initiatives catered to MWIDSM should focus on improved campaigns and expanding PrEP accessibility in existing healthcare, harm reduction, and social services.

Transgender women are disproportionately affected by sexual violence and corresponding mental health sequelae; however, many do not access healthcare due to experiences with transphobia. This analysis evaluated the association between sexual violence and suicidal ideation and the moderating effect of having a healthcare provider (HCP) with whom transgender women were comfortable discussing gender-related issues ("gender-affirming HCP"). We analyzed cross-sectional data from the Centers for Disease Control and Prevention's National HIV Behavioral Surveillance among Transgender Women (NHBS-Trans). Transgender women were recruited using respondent-driven sampling from seven urban areas from 2019 to 2020 and participated in an HIV biobehavioral survey. This analysis was restricted to transgender women who visited a HCP in the past 12 months ("healthcare-seeking transgender women" [HSTW]) (N = 1,489). Log-linked Poisson regression models provided adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) to estimate the association between sexual violence and suicidal ideation in the past 12 months. The interaction between sexual violence and having a gender-affirming HCP was statistically significant (p-value = .034). Among 1,489 HSTW, 225 (15.1%) experienced sexual violence and 261 (17.5%) reported suicidal ideation; 1,203 (80.8%) reported having a gender-affirming HCP. Sexual violence was associated with suicidal ideation (aPR = 2.65, 95% CI [2.08, 3.38]); the association was notably higher among those who did not have a gender-affirming HCP (aPR = 3.61, [2.17, 6.02]) than among those who did (aPR = 1.87, [1.48, 2.37]). Eliminating transphobia and promoting trauma- and violence-informed approaches in healthcare are necessary for sexual violence and suicide prevention among HSTW.

Transgender women experience discrimination in many settings, including in employment. Because employment and health insurance are intertwined in the United States, employment discrimination might be related to lower health insurance coverage and health care use, including gender-affirming care. This analysis used data from transgender women (N = 1,608) in seven urban areas in the United States collected during 2019-2020 to present the prevalence of six discrimination types (employment, housing, bathroom, businesses, health care, and abuse) and to measure the association between employment discrimination (defined as trouble getting a job or fired due to being transgender) and sociodemographic characteristics, health care access, and health care use. Log-linked Poisson regression models were conducted to estimate adjusted prevalence ratios and 95% CIs. Seven in 10 transgender women experienced at least one type of discrimination during the past 12 months. During the same period, 9.9% of transgender women were fired and 32.4% had trouble getting a job because of being transgender. Employment discrimination was associated with younger age and lower socioeconomic status. Having trouble getting a job was associated with health care access and health care use factors, including having no health insurance or having Medicaid only, having an unmet medical need because of cost, never having transgender-specific care, and having an unmet need for gender-affirming procedures. These findings suggest that employment discrimination contributes to transgender women's economic marginalization and their ability to obtain adequate health insurance coverage and achieve their transition goals. These findings might help guide efforts that protect transgender women's right to pursue their work, health, and life goals without discrimination.

Violence and harassment toward transgender women are associated with suicidal thoughts and behaviors, and social support might moderate such association. This analysis explored the association between certain forms of violence and harassment and suicidal ideation and moderation by social support. Better understanding of these associations could guide mental health services and structural interventions appropriate to lived experiences of transgender women. This cross-sectional analysis used data from CDC's National HIV Behavioral Surveillance Among Transgender Women. During 2019-2020, transgender women were recruited via respondent-driven sampling from seven urban areas in the United States for an HIV biobehavioral survey. The association between experiencing certain forms of violence and harassment (i.e., gender-based verbal and physical abuse or harassment, physical intimate partner abuse or harassment, and sexual violence) and suicidal ideation was measured using adjusted prevalence ratios and 95% CIs generated from log-linked Poisson regression models controlling for respondent-driven sampling design and confounders. To examine moderation, the extents of social support from family, friends, and significant others were assessed for interaction with certain forms of violence and harassment; if p interaction was <0.05, stratified adjusted prevalence ratios were presented. Among 1,608 transgender women, 59.7% experienced certain forms of violence and harassment and 17.7% reported suicidal ideation during the past 12 months; 75.2% reported high social support from significant others, 69.4% from friends, and 46.8% from family. Experiencing certain forms of violence and harassment and having low-moderate social support from any source was associated with higher prevalence of suicidal ideation. Social support from family moderated the association between experiencing certain forms of violence and harassment and suicidal ideation (p interaction = 0.01); however, even in the presence of high family social support, experiencing certain forms of violence and harassment was associated with higher prevalence of suicidal ideation. Social support did not completely moderate the positive association between experiencing violence and harassment and suicidal ideation. Further understanding of the social support dynamics of transgender women might improve the quality and use of social support. Policymakers and health care workers should work closely with transgender women communities to reduce the prevalence of violence, harassment, and suicide by implementing integrated, holistic, and transinclusive approaches.

Transgender women, especially transgender women of color, are disproportionately affected by HIV. However, no surveillance system collects data on HIV risk factors among this population. To address this gap, CDC developed a surveillance system entitled National HIV Behavioral Surveillance Among Transgender Women (NHBS-Trans) to assess behavioral and contextual data through systematic biobehavioral surveillance to monitor behavioral risk factors, prevention usage, and HIV prevalence among transgender women. NHBS-Trans used respondent-driven sampling in seven urban areas in the United States. Trained interviewers used a standardized, anonymous questionnaire to collect information on HIV-related behavioral risk factors, HIV testing, and use of prevention services. Each of the seven participating project areas recruited approximately 200 eligible transgender women and offered anonymous HIV testing. Overall, in the seven project areas, 1,757 participants completed the eligibility screener for NHBS-Trans during 2019-2020; of these, 6.6% were seeds (i.e., a limited number of initial participants who were chosen by referrals from persons and community-based organizations who knew or were part of the local population of transgender women). A total of 1,637 (93.2%) participants were eligible, consented, and completed the interview. Of these, 1,624 (99.2%) agreed to HIV testing. Of the total 1,637 participants, 29 participants did not report identity of woman or transgender woman, resulting in a final sample of 1,608 transgender women. NHBS-Trans project area staff members (n = 14) reported that the survey was timely and addressed a critical need for HIV surveillance in a population that is often overlooked. The MMWR supplement includes this overview report on NHBS-Trans, which describes the methods (history, participant eligibility criteria, questionnaire, data collection, and HIV testing) as well as evaluation of project implementation and the performance of the questionnaire content, specifically the acceptability for transgender women. The other NHBS-Trans reports in the supplement include information on pre-exposure prophylaxis use, psychosocial syndemic conditions and condomless anal intercourse, nonprescription hormone use, homelessness, discrimination and the association between employment discrimination and health care access and use, and social support and the association between certain types of violence and harassment (gender-based verbal and physical abuse or harassment, physical intimate partner abuse or harassment, and sexual violence) and suicidal ideation. NHBS-Trans provides important data related to the goals of the Ending the HIV Epidemic in the U.S. initiative. Findings from NHBS-Trans can help guide community leaders, clinicians, and public health officials in improving access to and use of HIV prevention and treatment services by transgender women.

Transgender women experience high prevalence of homelessness, which can affect their likelihood of acquiring HIV infection and can lead to poor medical outcomes. CDC analyzed data from the National HIV Behavioral Surveillance Among Transgender Women to identify whether personal characteristics and social factors affecting transgender women were associated with duration of homelessness during the past 12 months. Longer duration and chronic homelessness might indicate greater unmet needs, which increases their likelihood for acquiring HIV infection. Ordinal logistic regression was conducted to calculate adjusted prevalence odds ratios and 95% CIs for transgender women from seven urban areas in the United States experiencing homelessness 30-365 nights, 1-29 nights, and zero nights during the past 12 months. Among 1,566 transgender women, 9% reported 1-29 nights homeless and 31% reported 30-365 nights homeless during the past 12 months. Among participants who reported physical intimate partner violence or forced sex, 50% and 47%, respectively, reported experiencing 30-365 nights homeless. Furthermore, 55% who had been evicted or denied housing because of their gender identity and 58% who had been incarcerated during the past year experienced 30-365 nights homeless. The odds of transgender women experiencing longer duration of homelessness was associated with being younger and having a disability; higher psychological distress scores were associated with longer duration of homelessness. Analysis of social determinants of health found transgender women experiencing longer homelessness to be less educated, living below the Federal poverty level, and having lower social support. Therefore, focusing on HIV prevention and interventions addressing housing instability to reduce the duration of homelessness among transgender women is important. Further, integrating housing services with behavioral health services and clinical care, specifically designed for transgender women, could reduce HIV acquisition risk and improve HIV infection outcomes.

People experiencing homelessness (PEH) are at disproportionate risk of becoming infected and having severe illness from coronavirus disease 2019 (COVID-19), especially when residing in congregate settings like homeless shelters. Behavioral health problems related to substance use disorder (SUD) and severe mental illness (SMI) may have created additional challenges for PEH to practice prevention measures like mask wearing, physical distancing, handwashing, and quarantine and isolation. The study objective was to understand the perceived barriers PEH face regarding COVID-19 non-pharmaceutical prevention strategies and identify recommendations for overcoming barriers. From August-October 2020, qualitative phone interviews with 50 purposively selected behavioral health professionals across the United States serving PEH with SUD or SMI were conducted. Professionals described that PEH faced barriers to prevention that were structural (e.g., access to necessary resources), behavioral (related to SUD or SMI), or related to the priority of other needs. Recommendations to overcome these barriers included providing free prevention resources (e.g., masks and hand sanitizer), providing education about importance of prevention strategies, and prioritizing access to stable housing. Interviews took place before COVID-19 vaccines were available, so barriers to vaccination are not included in this paper. Findings can help support tailored approaches during COVID-19 and future public health threats.

Introduction: Environmental heat can have a negative impact on health, leading to increased healthcare utilization, disability, and death. Specific clinical conditions, in combination with a global rise in temperature, may amplify the risk of heat related illnesses. Materials and Methods: We conducted a retrospective analysis of VA's national electronic health record database from January 1, 2002, through December 31, 2019. Heat related illness diagnoses were assessed for associations with patient demographics, comorbidities, and geographic residence at the time of a heat related illness diagnosis. Descriptive statistics, linear regression, and additive seasonal decomposition methods were utilized to assess risk factors and trends. Results: There were 33,114 documented cases of heat related illness, which impacted 28,039 unique patients, during our 18 year assessment period. Veterans were diagnosed with heat related illnesses in all 50 US states and there was an increase in the rate over time. The likelihood of heat related illnesses was greater for those with increased comorbidity burden. Rates increased for homeless Veterans in the first half of the assessment period, and then declined for the second half. Black, as well as American Indian/Alaska Native Veterans accounted for a greater proportion of heat related illnesses. Conclusion: There has been a statistically significant and clinically important increase in the incidence of heat related illnesses over time. There has also been an increased number of heat related diagnoses associated with existing health and demographic factors, and the increase over time did not strictly follow the expected geographic North-South climate trends. © 2023

Despite recent declines in numbers of people who inject drugs (PWID) diagnosed with HIV, clusters of HIV among PWID are ongoing, especially among PWID experiencing homelessness. Using data from the National HIV Behavioral Surveillance in 2018, we evaluated the association between homelessness and injection risk and prevention behaviors among HIV-negative PWID who were recruited by respondent-driven sampling in 23 U.S. cities. Interviewers assessed sociodemographic characteristics, history of overdose, and behavioral risk and prevention factors for HIV. Adjusted prevalence ratios (aPR) and 95% CI were obtained using Poisson regression models. Of 10,614 HIV-negative PWID participants, 7275 (68.5%) reported experiencing homelessness. Homeless PWID were more likely than those who were not to be younger age, white, unemployed, without health insurance, in poverty, experiencing psychological distress, and incarcerated in the past 12 months. PWID experiencing homelessness were significantly more likely to report injection risk behaviors [share syringes/equipment (aPR = 1.26; 95% CI = 1.20-1.33), non-fatal opioid overdose (aPR = 1.64; 95% CI = 1.49-1.79)] and prevention behaviors [testing for HIV in past 12 months (aPR = 1.18; 95% CI = 1.12-1.24) and using syringe services programs (aPR = 1.09; 95% CI = 1.03-1.16)] than PWID not experiencing homelessness. Homelessness among PWID is associated with injection risk behaviors and non-fatal overdose.

The United States is experiencing a syndemic of homelessness, substance use disorder, and mental health conditions, which has been further exacerbated by the COVID-19 pandemic. Although it is expected that mitigation strategies will curb community transmission of COVID-19, the unintended consequences of social isolation on mental health and substance use are a growing public health concern. Awareness of changing mental health and substance use treatment needs due to the pandemic is critical to understanding what additional services and support are needed during and post-pandemic, particularly among people experiencing homelessness who have pre-existing serious mental illness or substance use disorder. To evaluate these effects and support our understanding of mental health and substance use outcomes of the COVID-19 pandemic, we conducted a qualitative study where behavioral health providers serving people experiencing homelessness described the impact of COVID-19 among their clients throughout the United States. Behavioral health providers shared that experiencing social isolation worsened mental health conditions and caused some people to return to substance use and fatally overdose. However, some changes initiated during the pandemic resulted in positive outcomes, such as increased client willingness to discuss mental health topics. Our findings provide additional evidence that the social isolation experienced during the pandemic has been detrimental to mental health and substance use outcomes, especially for people experiencing homelessness.

Persons who inject drugs (PWID) and exchange sex face disproportionate HIV rates. We assessed prevalence of exchange sex (receiving money/drugs for sex from ≥ 1 male partner(s) during the past year) among cisgender PWID, separately for women and men with a history of sex with men (MSM). We examined factors associated with exchange sex, including sociodemographic characteristics, sexual and drug use behaviors, and healthcare access/utilization. Over one-third of the 4657 participants reported exchange sex (women: 36.2%; MSM: 34.8%). Women who exchanged sex (WES) were significantly more likely to test HIV-positive than other women. Men who exchanged sex with men (MESM) showed a similar trend. WES and MESM shared many characteristics, including being uninsured, experiencing recent homelessness, condomless sex, polydrug use, and receptive/distributive needle sharing. These findings highlight a need to strengthen prevention interventions and address structural determinants of HIV for WES and MESM, particularly PWID who exchange sex.

The COVID-19 pandemic caused disruptions in behavioral health services (BHS), essential for people experiencing homelessness (PEH). BHS changes created barriers to care and opportunities for innovative strategies for reaching PEH. The authors conducted 50 qualitative interviews with behavioral health providers in the USA during August-October 2020 to explore their observations of BHS changes for PEH. Interviews were transcribed and entered into MAXQDA for analysis and to identify salient themes. The largest impact from COVID-19 was the closure or limited hours for BHS and homeless shelters due to mandated "stay-at-home" orders or staff working remotely leading to a disconnection in services and housing linkages. Most providers initiated telehealth services for clients, yielding positive outcomes. Implications for BHS are the need for long-term strategies, such as advances in communication technology to support BHS and homeless services and to ensure the needs of underserved populations are met during public health emergencies.

ABSTRACTIntimate partner violence (IPV) can increase a person's risk of HIV and other sexually transmitted infections (STIs), and may affect access to sexual health services. We assessed the prevalence of HIV screening and IPV among heterosexually-active persons using data from the 2016 National HIV Behavioral Surveillance. Participants were eligible if they were 18-60 years old, could complete the interview in English or Spanish, and reported having sex with an opposite sex partner in the previous 12 months. People who reported neither injection drug use within the past 12 months nor prior HIV diagnosis, and persons with valid responses to questions regarding HIV screening and physical/sexual IPV within the past 12 months were included (N = 7,777). Overall, 17% reported IPV in the previous 12 months and 19% had never had HIV screening. Abused persons were more likely to have been screened for HIV and to report high risk behaviors than non-abused persons. There was no difference in the proportion being offered HIV screening by their health care provider in the previous year. Findings suggest an integrated approach to violence prevention and sexual health may help increase awareness about clinical best practices and reduce risk for HIV/STIs among at-risk communities.

National prevalence of physical and sexual violence and its relationship to sexual behaviors are unknown among men who have sex with men (MSM). We estimated 12-month prevalence of physical and sexual violence and assessed relationships between violence and sexual behaviors among MSM. Data were obtained from National HIV Behavioral Surveillance 2017 that used time-space sampling methods to recruit and interview MSM in 22 U.S. cities. Weighted percentages with 95% confidence intervals (CI) were reported. Adjusted prevalence ratios (aPR) and 95% CIs were calculated using logistic regression with predicted marginal means. Overall, 10.2% (95% CI: 9.3%-11.2%) of MSM experienced physical violence only, 3.2% (95% CI: 2.7%-3.7%) experienced sexual violence only, and 2.3% (95% CI: 1.9%-2.7%) experienced both types of violence, in the past 12 months. Compared to MSM who did not experience violence, those who did reported higher percentages of unemployment, poverty, homelessness, same-sex discrimination, non-injection drug use, and binge drinking. Violence was not independently associated with condomless anal sex among MSM. MSM who experienced both types of violence were more likely than those who did not experience violence to have had four or more male sex partners (aPR=1.18, 95% CI: 1.02-1.37). MSM who experienced both types of violence (aPR=2.49, 95% CI: 1.52-4.09), sexual violence (aPR=2.27, 95% CI: 1.47-3.52), or physical violence (aPR=1.76, 95% CI: 1.27-2.44) were more likely than those who did not experience violence to have had exchange sex. Recent physical violence and sexual violence are common among MSM. Findings highlight the importance of violence screening and suggest the need for tailored interventions that improve the safety and economic security of MSM who experience violence, including those who exchange sex.

BACKGROUND: Men who have sex with men (MSM) accounted for two thirds of new HIV infections in the United States in 2019 despite representing approximately 2% of the adult population. METHODS: CDC analyzed surveillance data to determine trends in estimated new HIV infections and to assess measures of undiagnosed infection and HIV prevention and treatment services including HIV testing, preexposure prophylaxis (PrEP) use, antiretroviral therapy (ART) adherence, and viral suppression, as well as HIV-related stigma. RESULTS: The estimated number of new HIV infections among MSM was 25,100 in 2010 and 23,100 in 2019. New infections decreased significantly among White MSM but did not decrease among Black or African American (Black) MSM and Hispanic/Latino MSM. New infections increased among MSM aged 25-34 years. During 2019, approximately 83% of Black MSM and 80% of Hispanic/Latino MSM compared with 90% of White MSM with HIV had received an HIV diagnosis. The lowest percentage of diagnosed infection was among MSM aged 13-24 years (55%). Among MSM with a likely PrEP indication, discussions about PrEP with a provider and PrEP use were lower among Black MSM (47% and 27%, respectively) and Hispanic/Latino MSM (45% and 31%) than among White MSM (59% and 42%). Among MSM with an HIV diagnosis, adherence to ART and viral suppression were lower among Black MSM (48% and 62%, respectively) and Hispanic/Latino MSM (59% and 67%) compared with White MSM (64% and 74%). Experiences of HIV-related stigma among those with an HIV diagnosis were higher among Black MSM (median = 33; scale = 0-100) and Hispanic/Latino MSM (32) compared with White MSM (26). MSM aged 18-24 years had the lowest adherence to ART (45%) and the highest median stigma score (39). CONCLUSION: Improving access to and use of HIV services for MSM, especially Black MSM, Hispanic/Latino MSM, and younger MSM, and addressing social determinants of health, such as HIV-related stigma, that contribute to unequal outcomes will be essential to end the HIV epidemic in the United States.

People experiencing homelessness (PEH) are at higher risk for chronic health conditions, but clinical characteristics and outcomes for PEH hospitalized with COVID-19 are not known. We analyzed population-based surveillance data of COVID-19-associated hospitalizations during March 1-May 31, 2020. Two percent of the people hospitalized with COVID-19 for whom a housing status was recorded were homeless. Of 199 cases in the analytic sample, most were of racial/ethnic minority groups, and had underlying health conditions. Clinical outcomes such as ICU admission, respiratory support including mechanical ventilation, and deaths were documented. Hispanic and Non-Hispanic Black persons accounted for most mechanical ventilation and deaths. Severe illness was common among persons experiencing homelessness who were hospitalized with COVID-19.

Poverty, crowded housing, and other community attributes associated with social vulnerability increase a community's risk for adverse health outcomes during and following a public health event (1). CDC uses standard criteria to identify U.S. counties with rapidly increasing coronavirus disease 2019 (COVID-19) incidence (hotspot counties) to support health departments in coordinating public health responses (2). County-level data on COVID-19 cases during June 1-July 25, 2020 and from the 2018 CDC social vulnerability index (SVI) were analyzed to examine associations between social vulnerability and hotspot detection and to describe incidence after hotspot detection. Areas with greater social vulnerabilities, particularly those related to higher representation of racial and ethnic minority residents (risk ratio [RR] = 5.3; 95% confidence interval [CI] = 4.4-6.4), density of housing units per structure (RR = 3.1; 95% CI = 2.7-3.6), and crowded housing units (i.e., more persons than rooms) (RR = 2.0; 95% CI = 1.8-2.3), were more likely to become hotspots, especially in less urban areas. Among hotspot counties, those with greater social vulnerability had higher COVID-19 incidence during the 14 days after detection (212-234 cases per 100,000 persons for highest SVI quartile versus 35-131 cases per 100,000 persons for other quartiles). Focused public health action at the federal, state, and local levels is needed not only to prevent communities with greater social vulnerability from becoming hotspots but also to decrease persistently high incidence among hotspot counties that are socially vulnerable.

The geographic areas in the United States most affected by the coronavirus disease 2019 (COVID-19) pandemic have changed over time. On May 7, 2020, CDC, with other federal agencies, began identifying counties with increasing COVID-19 incidence (hotspots) to better understand transmission dynamics and offer targeted support to health departments in affected communities. Data for January 22-July 15, 2020, were analyzed retrospectively (January 22-May 6) and prospectively (May 7-July 15) to detect hotspot counties. No counties met hotspot criteria during January 22-March 7, 2020. During March 8-July 15, 2020, 818 counties met hotspot criteria for ≥1 day; these counties included 80% of the U.S. population. The daily number of counties meeting hotspot criteria peaked in early April, decreased and stabilized during mid-April-early June, then increased again during late June-early July. The percentage of counties in the South and West Census regions* meeting hotspot criteria increased from 10% and 13%, respectively, during March-April to 28% and 22%, respectively, during June-July. Identification of community transmission as a contributing factor increased over time, whereas identification of outbreaks in long-term care facilities, food processing facilities, correctional facilities, or other workplaces as contributing factors decreased. Identification of hotspot counties and understanding how they change over time can help prioritize and target implementation of U.S. public health response activities.

Objective: There are no nationally representative studies using a probability sample that have been published examining whether physicians recommend complementary health approaches (CHAs) to their patients, as previous research has focused only on selected medical specialties or a particular U.S. region. This article fills a void in the current literature for robust data on recommendations for CHAs by office-based physicians in the United States. Design: Descriptive statistics and multivariable regression analyses of physician-level data were from the 2012 Physician Induction Interview of the National Ambulatory Medical Care Survey (NAMCS PII), a nationally representative survey of office-based physicians. Weighted response rate among eligible physicians sampled for the 2012 NAMCS PII was 59.7%. Setting/Location: United States. Outcome measures: Recommendations by physicians to their patients for any CHA, and individual CHAs: massage therapy, herbs/nonvitamin supplements, chiropractic/osteopathic manipulation, yoga, acupuncture, and mind-body therapies. Differences in recommendations by physician demographic characteristics were identified. Results: Massage therapy was the most commonly recommended CHA (30.4%), followed by chiropractic/osteopathic manipulation (27.1%), herbs/nonvitamin supplements (26.5%), yoga (25.6%), and acupuncture (22.4%). The most commonly recommended CHAs by general/family practice physicians were chiropractic/osteopathic manipulation (54.0%) and massage therapy (52.6%). Of all U.S. physicians, 53.1% recommended at least one CHA to patients during the previous 12 months. Multivariable analyses found physician's sex, race, specialty, and U.S. region to be significant predictors of CHA recommendations. Female physicians were more likely than male physicians to recommend massage therapy (adjusted odds ratio [aOR] = 1.76, 95% confidence interval [CI] = 1.40-2.20), herbs/nonvitamin supplements (aOR = 1.85, 95% CI = 1.46-2.35), yoga (aOR = 2.16, 95% CI = 1.70-2.75), acupuncture (aOR = 1.65, 95% CI = 1.27-2.13), and mind-body therapies (aOR = 2.63, 95% CI = 2.02-3.41) to patients. Psychiatrists (aOR = 0.13, 95% CI = 0.07-0.23), OB/GYNs (aOR = 0.38, 95% CI = 0.24-0.60), and pediatricians (aOR = 0.26, 95% CI = 0.18-0.38) were all less likely to recommend chiropractic/osteopathic manipulation than general and family practitioners. Conclusions: Overall, more than half of office-based physicians recommended at least one CHA to their patients. Female physicians recommended every individual CHA at a higher rate than male physicians except for chiropractic and osteopathic manipulation. These findings may enable consumers, physicians, and medical schools to better understand potential differences in use of CHAs with patients.

In 2017, preliminary data show that gay, bisexual, and other men who have sex with men (MSM) accounted for 67% of new diagnoses of human immunodeficiency virus (HIV) infection, that MSM who inject drugs accounted for an additional 3%, and that African American/black (black) and Hispanic/Latino (Hispanic) MSM were disproportionately affected (1). During 2010-2015, racial/ethnic disparities in HIV incidence increased among MSM; in 2015, rates among black and Hispanic MSM were 10.5 and 4.9 times as high, respectively, as the rate among white MSM (compared with 9.2 and 3.8 times as high, respectively, in 2010) (2). Increased use of preexposure prophylaxis (PrEP), which reduces the risk for sexual acquisition of HIV infection by approximately 99% when taken daily as prescribed,* would help to reduce these disparities and support the Ending the HIV Epidemic: A Plan for America initiative(dagger) (3). Although PrEP use has increased among all MSM since 2014 (4), racial/ethnic disparities in PrEP use could increase existing disparities in HIV incidence among MSM (5). To understand racial/ethnic disparities in PrEP awareness, discussion with a health care provider, and use (steps in the HIV PrEP continuum of care) (6), CDC analyzed 2017 National HIV Behavioral Surveillance (NHBS) data. Black and Hispanic MSM were significantly less likely than were white MSM to be aware of PrEP, to have discussed PrEP with a health care provider, or to have used PrEP within the past year. Among those who had discussed PrEP with a health care provider within the past year, 68% of white MSM, 62% of Hispanic MSM, and 55% of black MSM, reported PrEP use. Prevention efforts need to increase PrEP use among all MSM and target eliminating racial/ethnic disparities in PrEP use.( section sign).

In February 2019, the U.S. Department of Health and Human Services proposed a strategic initiative to end the human immunodeficiency (HIV) epidemic in the United States by reducing new HIV infections by 90% during 2020-2030* (1). Phase 1 of the Ending the HIV Epidemic initiative focuses on Washington, DC; San Juan, Puerto Rico; and 48 counties where the majority of new diagnoses of HIV infection in 2016 and 2017 were concentrated and on seven states with a disproportionate occurrence of HIV in rural areas relative to other states.(dagger) One of the four pillars in the initiative is protecting persons at risk for HIV infection using proven, comprehensive prevention approaches and treatments, such as HIV preexposure prophylaxis (PrEP), which is the use of antiretroviral medications that have proven effective at preventing infection among persons at risk for acquiring HIV. In 2014, CDC released clinical PrEP guidelines to health care providers (2) and intensified efforts to raise awareness and increase the use of PrEP among persons at risk for infection, including gay, bisexual, and other men who have sex with men (MSM), a group that accounted for an estimated 68% of new HIV infections in 2016 (3). Data from CDC's National HIV Behavioral Surveillance (NHBS) were collected in 20 U.S. urban areas in 2014 and 2017, covering 26 of the geographic areas included in Phase I of the Ending the HIV Epidemic initiative, and were compared to assess changes in PrEP awareness and use among MSM. From 2014 to 2017, PrEP awareness increased by 50% overall, with >80% of MSM in 17 of the 20 urban areas reporting PrEP awareness in 2017. Among MSM with likely indications for PrEP (e.g., sexual risk behaviors or recent bacterial sexually transmitted infection [STI]), use of PrEP increased by approximately 500% from 6% to 35%, with significant increases observed in all urban areas and in almost all demographic subgroups. Despite this progress, PrEP use among MSM, especially among black and Hispanic MSM, remains low. Continued efforts to improve coverage are needed to reach the goal of 90% reduction in HIV incidence by 2030. In addition to developing new ways of connecting black and Hispanic MSM to health care providers through demonstration projects, CDC has developed resources and tools such as the Prescribe HIV Prevention program to enable health care providers to integrate PrEP into their clinical care.( section sign) By routinely testing their patients for HIV, assessing HIV-negative patients for risk behaviors, and prescribing PrEP as needed, health care providers can play a critical role in this effort.

BACKGROUND: Health departments prioritize investigations of reported reactive serologic tests based on age, gender, and titer using reactor grids. We wondered how reactor grids are used in different programs, and if administratively closing investigations of low-titer tests could lead to missed primary syphilis cases. METHODS: We obtained a convenience sample of reactor grids from 13 health departments. Interviews with staff from several jurisdictions described the role of grids in surveillance and intervention. From 5 jurisdictions, trends in reactive nontreponemal tests and syphilis cases over time (2006-2015) were assessed by gender, age, and titer. In addition, nationally-reported primary syphilis cases (2013-2015) were analyzed to determine what proportion had low titers (</=1:4) that might be administratively closed by grids without further investigation. RESULTS: Grids and follow-up approaches varied widely. Health departments in the study received a total of 48,573 to 496,503 reactive serologies over a 10-year period (3044-57,242 per year). In 2006 to 2015, the number of reactive serologies increased 37% to 169%. Increases were largely driven by tests for men although the ratios of tests per reported case remained stable over time. Almost one quarter of reported primary syphilis had low titers that would be excluded by most grids. The number of potentially missed primary syphilis cases varied by gender and age with 41- to 54-year-old men accounting for most. CONCLUSIONS: Reactor grids that close tests with low titers or from older individuals may miss some primary syphilis cases. Automatic, computerized record searches of all reactive serologic tests could help improve prioritization.

INTRODUCTION: Local health departments (LHDs) are increasingly using national standards to meet the challenges presented by the complex environments in which these agencies operate. Local boards of health (LBoHs) might play an instrumental role in improving LHDs' engagement in activities to meet these standards. OBJECTIVES: To assess the impact of LBoH performance of governance functions on LHDs having a current (completed within 5 years) community health assessment (CHA), community health improvement plan (CHIP), strategic plan, and level of engagement in the Public Health Accreditation Board (PHAB) accreditation program. METHODS: Binary and multinomial logistic regression models were used to analyze linked data from 329 LHDs participating in both the 2015 Local Board of Health Survey and the 2016 National Profile of LHDs Survey. RESULTS: Higher performance of LBoH governance functions, measured by an overall scale of LBoH taxonomy consisting of 60 items, had a significant positive effect on LHDs having completed CHA (P < .001), CHIP (P = .01), and strategic plan (P < .001). LHDs operating in communities with a higher score on the overall scale of LBoH taxonomy had significantly higher odds (P = .03) of having higher level of participation in the PHAB national voluntary accreditation program-that is, being accredited, having submitted application for accreditation, or being in the e-PHAB system (eg, by submitting a letter of intent). CONCLUSIONS: LBoHs serve as governance bodies for roughly 71% of LHDs and can play a significant role in encouraging LHDs' participation in these practices. That positive influence of LBoHs can be seen more clearly if the complexity and richness of LBoH governance functions and other characteristics are measured appropriately. The study findings suggest that LBoHs are a significant component of the public health system in the United States, having positive influence on LHDs having a CHA, CHIP, strategic plan, and participation in accreditation.

BACKGROUND: Chlamydial infections are common among young women and can lead to serious reproductive health complications. We assessed the risk of reported repeat chlamydial infection among young women in Louisiana and time interval between infections by age and race/ethnicity. METHODS: We analyzed surveillance data on chlamydial infections reported among women in Louisiana from January 1, 2000 to December 31, 2015. Multiple reports for the same person were matched using unique codes. Chlamydial infections reported more than 30 days after a previous positive test were considered new infections. Women aged 15-34 years at first infection during 2000-2012 were censored after three years or after they had a repeat infection. Cumulative incidence and incidence rate of repeat chlamydial infection among women were determined by year of first infection. Race- and age-specific results were obtained using stratified analyses. RESULTS: One in four women diagnosed with a chlamydial infection at 15-34 years of age in Louisiana had a reported repeat infection in three years or less. Risk of repeat infection increased for younger women, racial/ethnic minorities, and women in more recent cohorts. Young black women aged 15-19 years in 2012 had the highest risk (44%). Black women also had shorter intervals between infections than white women. CONCLUSIONS: Repeat chlamydial infections were common, especially among young black women. The true number is likely higher because surveillance data only count infections that were detected and reported. Comprehensive prevention strategies are needed to address high rates of repeat chlamydial infections among women.

OBJECTIVE: Routine ovarian cancer screening is ineffective; therefore, no professional organization recommends this screening in asymptomatic patients. However, many physicians have recommended screening, exposing patients to unnecessary risk. Little research exists on how nonprofessional experience with cancer influences physicians' screening practices. This study examines the association between physicians' nonprofessional experience with cancer and reported adherence to ovarian cancer screening guidelines. MATERIALS AND METHODS: A mail questionnaire with an annual examination vignette and questions about cancer screening recommendations was sent to a random sample of 3,200 U.S. family physicians, general internists, and obstetrician-gynecologists. This analysis included 497 physicians who received a vignette of a woman at average ovarian cancer risk and weighted results to represent these physician groups nationally. The outcome measure was adherence to ovarian cancer screening guidelines. Stepwise multivariate logistic regression estimated adjusted risk ratios for guideline adherence. RESULTS: In unadjusted analyses, 86.0% of physicians without nonprofessional cancer experience reported adherence to ovarian cancer screening guidelines compared with 69.2% of physicians with their own history of cancer, or a family member or close friend/coworker with cancer (p = 0.0045). In adjusted analyses, physicians with cancer themselves or in a family member or close friend/coworker were 0.82 times less likely (CI: 0.73-0.92) to report adhering to ovarian cancer screening recommendations than those without nonprofessional cancer experience. CONCLUSIONS: Despite recommendations to the contrary, many physicians reported recommending ovarian cancer screening in low-risk women. Physicians with nonprofessional cancer experience were more likely to report offering or ordering nonrecommended screening than physicians without this experience.

INTRODUCTION: The gravity, scale, and nature of human rights violations are severe in North Korea. Little is known about the mental health consequences of the lifelong exposures to these violations. METHODS: In 2014-2015, a retrospective study was conducted among 383 North Korean refugees in South Korea using respondent-driven sampling to access this hidden population. This study collected information on the full range of political and economic rights violations and measured post-traumatic stress disorder, anxiety and depression symptoms, and social functioning by standard instruments. Multivariate regression analysis was performed with the adjustment of political, economic, and demographic variables in 2016-2017. RESULTS: The results indicate elevated symptoms of anxiety (60.1%, 95% CI=54.3%, 65.7%), depression (56.3%, 95% CI=50.8%, 61.9%), and post-traumatic stress disorder (22.8%, 95% CI=18.6%, 27.4%), which are significantly associated with exposures to political rights violations (ten to 19 items versus non-exposure: anxiety AOR=16.78, p<0.001, depression AOR=12.52, p<0.001, post-traumatic stress disorder AOR=16.71, p<0.05), and economic rights violations (seven to 13 items versus non-exposure: anxiety AOR=5.68, p<0.001, depression AOR=4.23, p<0.01, post-traumatic stress disorder AOR=5.85, p<0.05). The mean score of social functioning was also lower in those who were exposed to political (adjusted difference= -13.29, p<0.001) and economic rights violations (adjusted difference= -11.20, p<0.001). CONCLUSIONS: This study highlights mental health consequences of lifelong human rights violations in North Korea. Beyond the conventional approach, it suggests the need for a collaborative preventive response from global health and human rights activists to address human rights in regard to mental health determinants of the 20 million people in North Korea.

BACKGROUND: Before searching prior records, sexually transmitted disease (STD) programs use syphilis reactor grids to exclude some reactive non-treponemal test results (RNTs) based on patient age, sex, and test titer. We propose a new algorithm that starts with comparing RNTs to previous syphilis non-treponemal tests and current treponemal test results. METHODS: De-duplicated RNTs from Florida's surveillance system (2006-2015) were extracted and stratified on morbidity. An algorithm was developed to triage RNTs. Sensitivity and specificity of the algorithm and the current reactor grid were estimated using reported syphilis cases. A random sample of cases missed by the proposed algorithm, stratified by stage of disease, were reviewed to verify case classification. RESULTS: Reported RNTs increased 58% from 2006 (n=34,808) to 2015 (n=55,001) (total=372,902). The current reactor grid removed 91,518 (24.5%) RNTs and missed 1,149 potential cases. Strictly following the reactor grid would result in a sensitivity of 97.4% and a specificity of 27.5%. The proposed algorithm would remove 242,078 (64.9%) RNTs and miss 2,768 potential cases. This results in a slightly lower sensitivity of 93.8%, but nearly triples the specificity, 72.9%. A review of a random sample of the 2,768 cases estimated that 72.7% would not have met the syphilis surveillance case definition resulting in an adjusted sensitivity of 98.4%. CONCLUSIONS: In Florida, an algorithm that starts by searching previous syphilis test results vastly improved specificity and slightly improved sensitivity compared to the current reactor grid. Implementing an automated algorithm could increase case ascertainment efficiency and further prioritize likely cases for investigation.

BACKGROUND: The success of an intervention to prevent syphilis will depend on the context and the goal of the intervention. To help programs choose interventions, we reviewed major changes in context and types of interventions that may be effective. METHODS: We reviewed the literature on the changing context of syphilis in the United States and interventions to prevent syphilis, focusing on papers that included evidence of effectiveness. RESULTS: Populations acquiring syphilis are constantly changing. Currently, incidence is very high among men who have sex with men. Among adults, late disease caused by syphilis has become rare. Congenital syphilis incidence has been low but is increasing, and morbidity and mortality remain high when babies are infected. Congenital syphilis now causes more deaths than syphilis among adults.Routine screening of MSM can identify and treat infections before they progress to disease (secondary prevention). Screening rates are highest when done as part of routine standing orders. Partner notification effectiveness has decreased, partly because many partners are anonymous. Most congenital syphilis can be prevented by screening pregnant women; it has been eliminated in areas where intense primary prevention efforts eliminated syphilis among women. CONCLUSION: So far, no program has stopped the increasing rates of infection among MSM, but secondary prevention efforts have prevented most disability. Congenital syphilis is increasing, and can be decreased by screening pregnant women and stopped by intensive efforts to prevent infection among women.

Background: Perinatal transmission is the major mode of hepatitis B virus (HBV) transmission and drives HBV endemicity in the US territory of Guam. We assessed correlates of prenatal hepatitis B surface antigen (HBsAg) screening and HBsAg positivity among pregnant women and evaluated the care of infants of HBsAg-positive women. Methods: Demographic and clinical data were abstracted from the maternal medical records of 966 randomly selected live infants born in 2014. Frequencies were calculated, and prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated using Poisson regression. Results: Among the mothers of the 966 infants, 78.2% were Pacific Islanders, 56.9% were >25 years old (born before universal infant hepatitis B vaccination in Guam), 89.0% received prenatal care (PNC), 96.7% underwent prenatal HBsAg screening, and 2.0% were HBsAg positive. Approximately 15% of the women who did not have PNC were not screened for HBsAg. Receipt of PNC was associated with HBsAg screening (adjusted PR, 1.13 [95% CI, 1.04-1.23]), and HBsAg positivity was associated with a maternal age of >25 years (adjusted PR, 6.80 [95% CI, 1.32-35.08]). All 18 infants of the HBsAg-positive mothers received hepatitis B vaccine, and 17 (94.4%) received hepatitis B immunoglobulin. Conclusion: Although the prenatal HBsAg screening prevalence in this sample was high, the maternal HBsAg prevalence among women in this sample was more than 14 times and 2 times the prevalence among US-born Pacific Islander/Asian women and all women in the continental United States, respectively. Improving access to PNC, ensuring that all pregnant women in Guam (especially those born before universal hepatitis B vaccination) are screened for HBsAg, and adopting postexposure prophylaxis for infants of HBsAg-positive mothers as standard clinical practice are important for preventing perinatal HBV transmission and reducing HBV endemicity.
