• The risk of SARS-CoV-2 reinfection among college students with prior infection was 2.2% (n = 16,101, 2,021 with and 14,080 without previous infection), while estimated protection from previous infection was 84% among students tested in fall 2020 and spring 2021 semesters at a large university in South Carolina. All students with access to main campus facilities were required to receive PCR testing in the fall, and students living in university housing were retested weekly. The median time to reinfection was 129 days, or about 4 months.
