Trichomoniasis and retesting in Durham County, North Carolina, United States, 2021 - 2022

Abstract

<jats:sec><jats:title>Background</jats:title><jats:p> The Centers for Disease Control and Prevention recommends universal retesting within 3 months after treatment of Trichomonas vaginalis infection given high rates of persistent infection or reinfection, or if this is not possible, within 12 months following treatment. Data is lacking on how often this is actually done. </jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p> We analyzed the demographic and clinical characteristics, rate of return for the recommended retesting, concordance between wet prep and nucleic acid amplification testing, and percent positivity for T. vaginalis on repeat vaginal specimens at a local public health department in Durham, North Carolina, United States. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> Of 193 females treated for trichomoniasis between March 1, 2021 – May 31, 2022, 83% were Black or African American and 44% between the ages of 20 and 29 years. Of these individuals, 32% had retesting performed within 3 months and 50% within 365 days after treatment. Females between the ages of 20 and 29 years were more likely to return for retesting than those between the ages of 30 and 39 years. Of those who returned for retesting, 10% were positive on repeat testing. </jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p> In this study, 50% of females diagnosed with trichomoniasis completed retesting within 365 days. Improved scheduling of clients at the time of trichomoniasis treatment and improved identification in our electronic health record of individuals diagnosed with trichomoniasis within the prior year would likely improve retesting rates. Given the high prevalence of trichomoniasis, expanded screening of asymptomatic females in settings where this is feasible may be warranted. </jats:p></jats:sec>
