ABSTRACT
OBJECTIVE: To communicate probable cases of COVID-19 reinfection in medical personnel. MATERIALS AND METHODS: A prospective, observational study performed from June to October 2020, in which information was collected on the cases of doctors who had COVID-19 reinfection. RESULTS: Twenty-four doctors with COVID-19 reinfection were included. The most frequent comorbidity in this group of cases was overweight or obesity in 15 patients (62%);7 individuals did not report any comorbidity and 3 of the cases suffered from systemic arterial hypertension, of which 2 also had obesity. CONCLUSIONS: The reinfection of COVID-19 is very likely and the SARS-CoV-2 virus does not provoke a perennial immunological memory in all infected individuals. © 2021 Comunicaciones Cientificas Mexicanas S.A. de C.V..
