Stigma has long accompanied sexually transmissible infections (STI) and hindered prevention and control efforts. It not only acts as a formidable barrier to STI testing, treatment and disclosure, but has a multitude of consequences for the health and quality of life of infected individuals. This review summarises the literature related to STI stigma and offers practical approaches to counter STI-associated stigma through multi-level efforts. Specifically, it describes the key sources that breed and perpetuate stigma, outlines how STI-associated stigma has been conceptualised and measured in the literature, documents the impact of stigma on infected and uninfected individuals, and summarises the stigma reduction strategies recommended in the literature. Gaps in the literature are identified and areas for further research are suggested, along with practical strategies for moving forward.

PrEP awareness is high and the use has rapidly increased over the last year among MSM in Seattle, Washington, USA. These findings demonstrate that high levels of PrEP use can be achieved among MSM at high-risk for HIV infection.

Background: Clinic-imposed barriers can impede access to medication for opioid use disorder (MOUD). We evaluated a low-barrier buprenorphine program that is co-located with a syringe services program (SSP) in Seattle, Washington, USA. Methods: We analyzed medical record data corresponding to patients who enrolled into the buprenorphine program in its first year of operation. We used descriptive statistics and tests of association to longitudinally evaluate retention, cumulative number of days buprenorphine was prescribed, and toxicology results. Results: Demand for buprenorphine among SSP clients initially surpassed programmatic capacity. Of the 146 enrolled patients, the majority (82%) were unstably housed. Patients were prescribed buprenorphine for a median of 47 days (interquartile range [IQR] = 8–147) in the 180 days following enrollment. Between the first and sixth visits, the percentage of toxicology tests that was positive for buprenorphine significantly increased (33% to 96%, P < .0001) and other opioids significantly decreased (90% to 41%, P < .0001) and plateaued thereafter. Toxicology test results for stimulants, benzodiazepines, and barbiturates did not significantly change. Conclusions: SSP served as an effective point of entry for a low-barrier MOUD program. A large proportion of enrolled patients demonstrated sustained retention and reductions in opioid use, despite housing instability and polysubstance use.

Context: Despite the massive scale of COVID-19 case investigation and contact tracing (CI/CT) programs operating worldwide, the evidence supporting the intervention's public health impact is limited. Objective: To evaluate the Public Health-Seattle & King County (PHSKC) CI/CT program, including its reach, timeliness, effect on isolation and quarantine (I&Q) adherence, and potential to mitigate pandemic-related hardships. Design: This program evaluation used descriptive statistics to analyze surveillance records, case and contact interviews, referral records, and survey data provided by a sample of cases who had recently ended isolation. Setting: The PHSKC is one of the largest governmental local health departments in the United States. It serves more than 2.2 million people who reside in Seattle and 38 other municipalities. Participants: King County residents who were diagnosed with COVID-19 between July 2020 and June 2021. Intervention: The PHSKC integrated COVID-19 CI/CT with prevention education and service provision. Results:The PHSKC CI/CT team interviewed 42 900 cases (82% of cases eligible for CI/CT), a mean of 6.1 days after symptom onset and 3.4 days after SARS-CoV-2 testing. Cases disclosed the names and addresses of 10 817 unique worksites (mean = 0.8/interview) and 11 432 other recently visited locations (mean = 0.5/interview) and provided contact information for 62 987 household members (mean = 2.7/interview) and 14 398 nonhousehold contacts (mean = 0.3/interview). The CI/CT team helped arrange COVID-19 testing for 5650 contacts, facilitated grocery delivery for 7253 households, and referred 9127 households for financial assistance. End of I&Q Survey participants (n = 304, 54% of sampled) reported self-notifying an average of 4 nonhousehold contacts and 69% agreed that the information and referrals provided by the CI/CT team helped them stay in isolation. Conclusions: In the 12-month evaluation period, CI/CT reached 42 611 households and identified thousands of exposure venues. The timing of CI/CT relative to infectiousness and difficulty eliciting nonhousehold contacts may have attenuated the intervention's effect. Through promotion of I&Q guidance and services, CI/CT can help mitigate pandemic-related hardships.

Background Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention strategy, but it is unclear how best to deliver PrEP to key populations. Drawing upon a cross-sectional survey of transgender women (TW) in Detroit, USA, and experience of a PrEP clinic that serves this population, this manuscript describes the following: (1) the risk profile of Detroit TW; (2) the proportion of TW with at least one PrEP indication; and (3) perceptions of and experiences with PrEP among TW in Detroit. Methods: Between August 2017 and March 2018, 126 TW completed an online PrEP survey. Survey responses were summarised using descriptive statistics and multivariable relative risk regression. Results: Among participants who reported a negative or unknown HIV status (76% of all participants), 56% reported risk behaviour(s) consistent with PrEP indication guidelines, 17% reported currently taking PrEP and another 4% reported discontinued PrEP use. Among participants who met an indication for PrEP but were not currently taking PrEP, 64% indicated that they were not interested in taking PrEP. Approximately 60% of participants who were not currently taking PrEP reported that they would be more likely to take PrEP if it were provided at a clinic that also provided hormone replacement therapy. Conclusions: Although a substantial proportion of TW in our survey were on PrEP, interest in PrEP among high-risk TW who were not taking it was low. Specialised clinical infrastructure that is responsive to the specific needs of TW may be needed to expand PrEP to this oftentimes marginalised and high-risk population.

To recruit participants, we placed banner and text-based pop-up advertisements in English and Spanish on social media, male-male geosocial networking, and general LGBTQ-interest apps and websites. Advertisements on all platforms were targeted based on location in Washington, and advertisements on social media were additionally targeted to males who reported an interest in relationships with men or expressed an interest in LGBTQ-related topics or groups.
