How the new coronavirus variant quickly accumulated 17 mutations

Immunocompromised patients experiencing prolonged infection with novel coronavirus when treated with convalescent plasma might trigger a strong selective pressure on the virus due to high concentration of antibodies. This might lead to the generation of large number of mutations. The new SARS-CoV-2 variant — B.1.1.7 — that was first seen in Kent and Greater London … Continue reading How the new coronavirus variant quickly accumulated 17 mutations

There is currently no evidence that the new variant can cause any change in disease severity or increase the risk of reinfection. While the mutations are unlikely to make the … Continue reading Emergence of a new coronavirus variant raises concerns
