Reinfections with Different SARS-CoV-2 Omicron Subvariants, France

Abstract

We describe 188 patients in France who were successively infected with different SARS-CoV-2 Omicron subvariants, including BA.1, BA.2, and BA.5. Time between 2 infections was <90 days for 50 (26.6%) patients and <60 days for 28 (14.9%) patients. This finding suggests that definitions for SARS-CoV-2 reinfection require revision.
