Investigation of SARS-CoV-2 suspected cases of reinfection among hospital staff members in the greater Paris area

After one year, among 236 hospital staff members (HSMs) tested positive for SARS-CoV-2, we observed 5 cases of suspected reinfection in our teaching hospital in France. No probable reinfection was retained considering PCR Cycle Threshold and clinical context. Focus should concern COVID-free HSMs still not vaccinated rather than the ones previously infected.
