Researchers identify risk factors for SARS-CoV-2 reinfection

Rss Feed - Fri, 04/16/2021 - 20:04
A team of scientists from the Capital Medical University and Peking University, China, has recently explored the factors responsible for the reactivation of SARS-CoV-2 infection among individuals who have recently recovered from COVID-19. The findings reveal that individuals with lower lymphocyte count or with two or fewer symptoms during the first COVID-19 episode are at higher risk of recurrent infection.

Numerous agents with anti-SARS-CoV-2 potential discovered with crystallographic screening
