Sars-Cov-2 B.1.1.7 Reinfection After Previous Covid-19 In Two Immunocompetent Italian Patients

To date only one case of SARS-COV-2 B.1.1.7 reinfection has been reported (1). We report here two more such reinfection cases in Lombardy residents that, nevertheless the ECDC statement of a period from 45 to 90 days to confirm a reinfection (2), experimented a second infection from a B.1.1.7 variant of SARS CoV-2 only one month after the first one. In both cases interstitial pneumonia requiring intubation or oxygen support was present at the time of first infection, whereas the second one was characterized by very mild development.
