Reinfection With Severe Acute Respiratory Syndrome Coronavirus 2 Among Previously Infected Healthcare Personnel and First Responders.

ABSTRACT:

Background

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus testing among first responders and healthcare personnel who participated in a May 2020-August 2020 serosurvey that assessed spike protein antibodies provided an opportunity to assess reinfection.

Methods

Participants with a positive virus test ≥14 days before their serology test were included. Reinfection was defined as a second positive SARS-CoV-2 test ≥90 days after the first positive test. The association between serostatus and reinfection was assessed with a proportional hazards model.

Results
