LOL. 30 seconds reading about Koch's postulates.
1. They cannot be applied to viruses.
2. They require that all of evolution is wrong.
3. They go against the latter discovery of asymptomatic carriers in both bacteria caused infections and viruses. Again, by definition do not apply to viruses anyway.
I wasn't thinking about Covid deniers in my first post anyway. I was thinking about people who think wifi or cell phones make you sick.
