Patterns and persistence of SARS-CoV-2 seropositivity among college students at Indiana University-Bloomington.

ABSTRACT:

Objective

This study examined the patterns and persistence of SARS-CoV-2 seropositivity among college students from March to November 2020. Using data from a sample of students at Indiana University, we assessed (1) the duration and seropositivity following reverse transcription-PCR (RT-PCR)-confirmed SARS-CoV-2 infection and (2) persistence of seropositivity over 10 weeks between two laboratory antibody test visits.

Setting, design and participants

The longitudinal study was conducted at Indiana University from September to November 2020, with two laboratory antibody tests, and included self-reported RT-PCR results before the observational period from as early as 20 March 2020. This 6-9 month period contributes to our understanding of seropositivity dynamics. The study incl
