FedUpJW:
How do you propose they breathe? Or are you saying they would have to have a completely self-contained air supply that was also isolated from any contamination from the air that surrounds the globe?
Come on, that’s not even a good straw man attack. COVID-19 isn’t an airborne virus in the manner implied.
It’s funny that certain people are so willing to accept an unverifiable anecdote about a self-assessment of diligent isolation.
The claim that ‘anyone with flu gets lumped in with COVID’ is obviously false because there are still flu statistics. Other posters have already provided information about why flu numbers were seasonally low, and the US is not currently in flu season.
