- Reinfection rate in a cohort of healthcare workers over 2 years of the COVID-19 pandemic(2023) GUEDES, Ana Rubia; OLIVEIRA, Maura S. S.; TAVARES, Bruno M. M.; LUNA-MUSCHI, Alessandra; LAZARI, Carolina dos Santos; MONTAL, Amanda C. C.; FARIA, Elizabeth de; MAIA, Fernando Liebhart; BARBOZA, Antonio dos Santos; LEME, Mariana Deckers; TOMAZINI, Francis M. M.; COSTA, Silvia Figueiredo; LEVIN, Anna S. S.In this large cohort of healthcare workers, we aimed to estimate the rate of reinfections by SARS-CoV-2 over 2 years of the COVID-19 pandemic. We investigated the proportion of reinfections among all the cases of SARS-CoV-2 infection from March 10, 2020 until March 10, 2022. Reinfection was defined as the appearance of new symptoms that on medical evaluation were suggestive of COVID-19 and confirmed by a positive RT-PCR. Symptoms had to occur more than 90 days after the previous infection. These 2 years were divided into time periods based on the different variants of concern (VOC) in the city of Sao Paulo. There were 37,729 medical consultations due to COVID-19 at the hospital's Health Workers Services; and 25,750 RT-PCR assays were performed, of which 23% (n = 5865) were positive. Reinfection by SARS-CoV-2 was identified in 5% (n = 284) of symptomatic cases. Most cases of reinfection occurred during the Omicron period (n = 251; 88%), representing a significant increase on the SARS-CoV-2 reinfection rate before and during the Omicron variant period (0.8% vs. 4.3%; p < 0.001). The mean interval between SARS-CoV-2 infections was 429 days (ranged from 122 to 674). The Omicron variant spread faster than Gamma and Delta variant. All SARS-CoV-2 reinfections were mild cases.
