The GISAID initiative promotes the rapid sharing of data from all influenza viruses and the SARS-CoV-2 coronavirus causing COVID-19. This includes genetic sequence and related clinical and epidemiological data associated with human viruses, and geographical as well as species-specific data associated with avian and other animal viruses, to help researchers understand how viruses evolve and spread during epidemics and pandemics.
