 The recover study aims to estimate the incidence of symptomatic and asymptomatic SARS-CoV-2 infections, examine risk factors for infection and clinical spectrum of illness, and assess the effectiveness of vaccination among essential workers. The study uses active surveillance, self-collected nasal swabs, blood collection, and text messages to collect data on participant demographics, medical history, vaccination history, symptoms, access to medical care, symptom duration, and SARS-CoV-2 infection status. Enrollment is ongoing at three of the six study sites, with a total of 2,623 actively enrolled participants as of February 2021, including 280 participants who have been found to be positive for SARS-CoV-2 by RT-PCR. Data collected through the cohort are expected to provide important public health information for essential workers at high risk for occupational exposure to SARS-CoV-2 and allow early evaluation of COVID-19 vaccine effectiveness.
