Background: Doxycycline post-exposure prophylaxis (doxy PEP) is increasingly used among men who have sex with men (MSM). Its impact on antimicrobial resistance and the microbiome is uncertain.

Methods: We used Neisseria gonorrhoeae (NG) surveillance data from King County, WA and joinpoint regression to investigate trends in NG-tetracycline resistance (tetR), 2017-2024 and, among sexual health clinic (SHC) patients, evaluated the association of NG-tetR with doxy PEP use.

Background: Sexual health clinics (SHCs) were frontline providers in the 2022 US mpox public health response, although data on clinic-based mpox vaccine scale-up, diagnoses, and treatment are limited. We describe the role of a public health SHC in King County's mpox response between May 23, 2022, and October 31, 2022.

Methods: In July 2022, the SHC implemented a dedicated vaccine clinic and presumptive tecovirimat treatment (before laboratory confirmation) with on-site dispensation.

Background: Anecdotal reports suggest that partner services (PS) are less successful among people with repeat sexually transmitted infection (STI) diagnoses and/or previous PS interactions. We examine whether having repeated STI diagnoses and/or PS interactions is associated with PS outcomes among men who have sex with men (MSM).

Methods: With STI surveillance and PS data for MSM diagnosed with gonorrhea, chlamydia, and/or syphilis from 2007 to 2018, in King County, WA, we used Poisson regression models to examine the relationships between PS outcomes (e.

Background: Current guidance from the US Centers for Disease Control and Prevention recommends empiric treatment for persons exposed to sexually transmitted infections, including Neisseria gonorrhoeae ( NG ). As an antimicrobial stewardship measure, some clinics now recommend a test and treat strategy, but reliance on urogenital testing only may miss cases.

Methods: We conducted a descriptive analysis of pharyngeal NG infection in men who have sex with women (MSW) and women seeking care at a sexual health clinic in Seattle, WA, from February 2017 to July 2021 because of sexual contact to a partner diagnosed with gonorrhea.

Background: There is conflicting evidence on whether prior azithromycin (AZM) exposure is associated with reduced susceptibility to AZM (AZMRS) among persons infected with Neisseria gonorrhoeae (NG).

Methods: The study population included Public Health-Seattle and King County Sexual Health Clinic (SHC) patients with culture-positive NG infection at ≥1 anatomic site whose isolates were tested for AZM susceptibility in 2012-2019. We used multivariate logistic regression to examine the association of time since last AZM prescription from the SHC in ≤12 months with subsequent diagnosis with AZMRS NG (minimum inhibitory concentration [MIC], ≥2.

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.

Background: Neisseria gonorrhoeae culture is required for antimicrobial susceptibility testing, but recovering isolates from clinical specimens is challenging. Although many variables influence culture recovery, studies evaluating the impact of culture specimen collection timing and patient symptom status are limited. This study analyzed urogenital and extragenital culture recovery data from Centers for Disease Control and Prevention's Strengthening the US Response to Resistant Gonorrhea (SURRG) program, a multisite project, which enhances local N.

Background: Reduced antibiotic susceptibility (RS) in Neisseria gonorrhoeae (GC) may increase treatment failure. Conducting tests of cure (TOC) for patients with RS-GC may facilitate identification of treatment failures.

Methods: We examined 2018 to 2019 data from 8 jurisdictions participating in the US Centers for Disease Control and Prevention's Strengthening US Response to Resistant Gonorrhea project.

Background: Partner notification services (PS) are often used to control sexually transmitted infections, but their effectiveness is limited by patients' reluctance to name sex partners. We hypothesized that being notified of having antimicrobial-resistant Neisseria gonorrhoeae (ARGC) would make patients more likely to provide named partner information.

Methods: We used King County, Washington STD surveillance and Strengthening the US Response to Resistant Gonorrhea data to identify gonorrhea cases.

Background: In response to the COVID-19 pandemic, Washington State's Stay Home, Stay Healthy (SHSH) order was implemented on March 24, 2020. We hypothesized that pandemic mitigation measures might reduce sexually transmitted infection (STI) screening and/or transmission.

Methods: We used King County, WA STI surveillance and sexual health clinic (SHC) data from January 1, 2019, to July 31, 2020.

Background: Pre-exposure prophylaxis (PrEP) is highly efficacious, but its effectiveness may be limited by poor adherence or discontinuation. Our objective was to estimate the effectiveness of real-world PrEP use in a population at increased risk of HIV infection.

Setting: King County, Washington.

Background: Neisseria gonorrhoeae culture is necessary to determine antimicrobial resistance, but typically requires specimen collection by clinicians. We sought to determine the sensitivity of patient-collected specimens for N. gonorrhoeae culture.

Introduction: Current Centers for Disease Control and Prevention guidelines recommend that clinicians empirically treat the sex partners of persons with Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) infection before confirming that they are infected. It is possible that this practice, known as epidemiologic treatment, results in overtreatment for uninfected persons and may contribute to development of antimicrobial resistance. We sought to quantify the number of patients who received epidemiologic treatment and the proportion of those who were overtreated.

The purpose of this study was to determine if anonymous and confidential testers differ in recency of human immunodeficiency virus (HIV) infection at time of testing and prevalence of antiretroviral drug (ARV) resistance. We examined data from the Centers for Disease Control and Prevention-sponsored Antiretroviral Drug Resistance Testing project, which performed genotypic testing on leftover HIV diagnostic serum specimens of confidentially and anonymously tested ARV-naïve persons newly diagnosed with HIV in Colorado (n = 365 at 11 sites) and King County, Washington (n = 492 at 44 sites). The serologic testing algorithm for recent HIV seroconversion was used to classify people as likely to have been recently infected or not.
