The good news is that according to infectious disease physician and clinical microbiologist Charles Chiu, “The virus mutates so slowly that the virus strains are fundamentally very similar to each other.” Scientists studying the virus have shared their knowledge to compile a genetic sequence map at NextStrain.org, an open-access website that shows how the various strains have traveled to different regions and countries. This finding is based on...
