Modern diagnosis of Trichomonas vaginalis infection

Recent advances in tests for the sexually transmitted protozoan parasite Trichomonas vaginalis have increased opportunities for diagnosis and treatment of this important sexually transmitted infection. This review summarises currently available tests, highlighting their performance characteristics, advantages and limitations. The recent development of molecular tests for the detection of T vaginalis, including rapid antigen detection and nucleic acid amplification tests, has significantly improved the quality of diagnostics for trichomoniasis, particularly in women. In light of the expanded menu of testing options now available, improved recognition and better control of trichomoniasis are in sight, which should enable the eventual reduction of adverse reproductive consequences associated with T vaginalis infection

From Health Disparities to Hotspots to Public Health Strategies: The Impact of the COVID-19 Pandemic in North Carolina

The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute coronavirus type 2 (SARS-CoV-2), has significantly affected the lives of many people across North Carolina and the United States. Similar to the rest of the country, the epidemiology of SARS-CoV-2 in the state indicates health disparities among Black and Hispanic/Latino individuals, the presence of hotspots, or counties with high numbers of infected persons, and clusters of transmission among congregate living facilities. There have been many advances in diagnostic methods for SARS-CoV-2 and therapies for hospitalized patients nationwide. Public health strategies have included widespread testing for SARS-CoV-2, optimal management of cases, contact tracing efforts, and a phased reopening of sectors/activities in North Carolina with masks and physical distancing to minimize spread of the virus. In this issue, several authors, researchers, and public health leaders discuss the challenges that North Carolinians have experienced with respect to COVID-19 and several factors that are likely contributing to the health disparities among racial/ethnic minorities who have had the highest number of cases and deaths from SARS-CoV-2. Additional strategies also reported in this issue include the use of strike teams and mobile units to reach populations at high risk for infection and severe illness. Promoting individual and population-level strategies for minimizing transmission of SARS-CoV-2, especially among the most vulnerable, and consistent public health messaging based on science are critical as we face the new year and continued uncertainties around the COVID-19 pandemic

Hepatitis C Virus Testing and Linkage to Care in North Carolina and South Carolina Jails, 2012–2014

We evaluated a hepatitis C virus (HCV) testing and linkage-to-care post-release program among detainees of small- to medium-sized jails in North Carolina and South Carolina as part of the Hepatitis Testing and Linkage to Care initiative

Feasibility and Acceptability of Door-to-Door Rapid HIV Testing Among Latino Immigrants and Their HIV Risk Factors in North Carolina

Latino immigrants in the United States are disproportionally impacted by the HIV epidemic but face barriers to clinic-based testing. We assessed a community-based strategy for rapid HIV testing by conducting “door-to-door” outreaches in apartments with predominately Latino immigrants in Durham, North Carolina, that has experienced an exponential growth in its Latino population. Eligible persons were 18 years or older, not pregnant, and reported no HIV test in the previous month. Participants were asked to complete a survey and offered rapid HIV testing. Of the 228 Latino participants, 75.4% consented to HIV testing. There was a high prevalence of sexual risk behaviors among participants, with 42.5% acknowledging ever having sex with a commercial sex worker (CSW). Most (66.5%) had no history of prior HIV testing. In bivariate analysis, perceived HIV risk, no history of HIV testing, sex with a CSW, sex in exchange for drugs or money, living with a partner, and alcohol use were significantly associated with test acceptance. In the multivariate analysis, participants who had never been tested for HIV were more likely to consent to rapid HIV testing than those who had tested in the past (adjusted odds ratio 2.5; 95% confidence interval [CI], 1.1, 5.6). Most participants supported rapid HIV testing in the community (97%). Door-to-door rapid HIV testing is a feasible and acceptable strategy for screening high-risk Latino immigrants in the community. Factors associated with HIV risk among Latino migrants and immigrants in the United States should be considered along with novel testing strategies in HIV prevention programs

Efforts at the Frontlines: Implementing a Hepatitis C Testing and Linkage-to-Care Program at the Local Public Health Level

The national Viral Hepatitis Action Plan recommends strengthening partnerships among health departments, community-based organizations, and health-care providers for hepatitis services. We implemented a hepatitis C virus (HCV) testing and linkage-to-care program through a local health department using similar strategies reported for HIV care

Rate of Decline in Nontreponemal Antibody Titers and Seroreversion After Treatment of Early Syphilis

Syphilis management is complex and demonstration of treatment response requires monitoring of nontreponemal antibody titers for a ≥ 4-fold decline and/or seroreversion to nonreactive titers

Cervicovaginal Microbiota Predicts Neisseria gonorrhoeae Clinical Presentation

Neisseria gonorrhoeae infection of the female lower genital tract can present with a spectrum of phenotypes ranging from asymptomatic carriage to symptomatic cervical inflammation, or cervicitis. The factors that contribute to the development of asymptomatic or symptomatic infections are largely uncharacterized. We conducted a pilot study to assess differences in the cervicovaginal microbial community of patients presenting with symptomatic vs. asymptomatic N. gonorrhoeae infections to a sexually transmitted infections (STI) clinic. DNA was isolated from cervicovaginal swab specimens from women who tested positive for N. gonorrhoeae infection using a clinical diagnostic nucleic acid amplification test. We performed deep sequencing of 16S ribosomal RNA gene amplicons, followed by microbiome analyses with QIIME, and species-specific real-time PCR to assess the composition of microbial communities cohabitating the lower genital tract with the infecting N. gonorrhoeae. Specimens collected from asymptomatic individuals with N. gonorrhoeae infection and no co-infection with Chlamydia trachomatis and/or Trichomonas vaginalis carried Lactobacillus-dominant microbial communities more frequently than symptomatic patients without co-infection. When compared to asymptomatic individuals, symptomatic women had microbial communities characterized by more diverse and heterogenous bacterial taxa, typically associated with bacterial vaginosis (BV) [Prevotella, Sneathia, Mycoplasma hominis, and Bacterial Vaginosis-Associated Bacterium-1 (BVAB1)/“Candidatus Lachnocurva vaginae”]. Both symptomatic and asymptomatic N. gonorrhoeae patients with additional STI co-infection displayed a BV-like microbial community. These findings suggest that Lactobacillus-dominant vaginal microbial community may protect individuals from developing symptoms during lower genital tract infection with N. gonorrhoeae

Mycoplasma genitalium Infection in Women Attending a Sexually Transmitted Infection Clinic: Diagnostic Specimen Type, Coinfections, and Predictors

In female sexually transmitted infection (STI) clinic attendees, Mycoplasma genitalium (MG) was more frequently detected using vaginal (53/73) versus endocervical (43/73) specimens. In women without other STIs, MG detection (N=44) was associated with age≤ 22 years (odds ratio (OR) 2.53, P=0.006) and clinical evidence of cervicitis (OR 2.11, P=0.03)

Home Screening for Bacterial Vaginosis to Prevent Sexually Transmitted Diseases

Background. Longitudinal studies have consistently found a significant association between bacterial vaginosis (BV) and acquisition of sexually transmitted diseases. However, there are limited prospective data to confirm these findings
