I have read about this site below which seems to very serious stuff, they work in collaboration with the WHO. It is using all sources available worldwide to get daily updated results, where and when was which step of mutation (pathogen evolution) of Covid 19 seen. It starts as early as December 20.2019. At least a scientific site and no BS.
