COVID-19 Contact Tracing Conundrums: Insights From the Front Lines.

COVID-19 contact tracing is an induction social network intervention in which the structure of the social network is leveraged to deploy proven COVID-19 interventions such as testing and social distancing. The Howard Brown Health organization has rapidly expanded to include COVID-19 testing, contact tracing, and linkage to resources since the first cases were identified in Chicago, Illinois. COVID-19 is penetrating the most vulnerable networks in the United States; existing inequities are widening as community resources and organizations have had to place services on hold.Here we address several questions that arise as organizations build capacity for contact tracing, including questions involving the potential impact of contact tracing, stakeholders who could be involved, the timing of contact tracing deployment, and the impact potential for digital technology.Contact tracing is critical at later stages of epidemic decline given the potential for isolated outbreaks as larger events, schools, stadiums, and festivals reopen. Local contact tracing efforts can have other indirect benefits with respect to limiting transmission, such as increasing testing rates and addressing structural barriers through provision of life-saving resources and access to crucial social support.

Preexposure Prophylaxis Initiation and Retention in Care Over 5 Years, 2012-2017: Are Quarterly Visits Too Much?

Retention in preexposure prophylaxis (PrEP) care is critical to elimination of human immunodeficiency virus. We reviewed all Howard Brown Health patients receiving PrEP (n = 5583) from 2012 to 2017. Among those with 12 months of follow-up, 43% remained in care, yet only 15% had all 4 quarters with a PrEP visit. Insurance status and comorbid conditions were drivers of retention in care.
