There are several genetic strains of COVID-19 circulating around the world. Information is found on NextStrain, an online resource for scientists that uses data from academic, independent and government laboratories all over the world to visually track the genomics of the SARS-CoV-2 virus. It currently represents genetic sequences of strains from 36 countries on six continents.
