SARS-CoV-2 reinfection caused by the P.1 lineage in Araraquara citySao Paulo State Brazil

摘要

Reinfection by the severe acute respiratory syndrome coronavirus type 2(SARS-COV-2) has been reported in many countries, suggesting that the virus maycontinue to circulate among humans despite the possibility of local herdimmunity due to massive previous infections. The emergence of variants ofconcern (VOC) that are more transmissible than the previous circulating ones hasraised particular concerns on the vaccines effectiveness and reinfection rates.The P.1 lineage was first identified in December 2020 in Manaus city and is nowglobally spread. We report the first case of reinfection of SARS-CoV-2 caused bythe P.1 variant outside of Manaus. The potential of these new variants to escapenaturally and vaccine- induced immunity highlights the need for a globalvigilance.
