Warobi: Part of what I did was to show that it was really a doctor in a hospital who went back and figured out what was going on. There was almost certainly a new virus in the town, both probably infectious and most often associated with the South China Seafood market. All of them were then delivered to local and state public health authorities.

Still, the information did not reach the national health authorities. Therefore, authorities, various levels, were unaware of this until late December. So, rather than knowing something was happening and obscuring things, there is no doubt that this surprised the authorities. And there was a lot of very ridiculous speculation that the Wuhan Institute of Vessels database would go offline in September, and somehow they were trying to hide things. Well, the virus almost certainly didn’t start circulating until November, perhaps early December.

There were individual doctors who noticed that there were quite a few sick patients from this market, but from December 27th to December 29th, no one was aware that there was probably a new virus.

Q: How do you know that the virus started to spread from mid to late November?

Warobi: The virus replicates itself, so it sometimes makes mistakes, and it makes mistakes every two weeks at a rate of one mutation per genome. Therefore, by late December, there were different genomes with 4 or 5 mutations. So, considering their ancestors, if it’s four mutations, it’s like two mutations under this branch and two mutations under that branch. Therefore, once every two weeks, it takes about a month to return to your ancestors. Therefore, the virus indicates that its evolution is likely to have been for a month or more.
