But we certainly don’t know now.
Any of it.
Including the warmth.
We don’t live in unairconditioned buildings any longer.
We shop in them.
We don’t work in them.
We’ll see if the temp has anything to do with this virus.
I suspect it’s more a question of circulating levels of D3 that shut the flu down in the summer. There are myriad papers linking D3 levels to flu susceptibility.
However, the general rule for viruses is they do well in cold weather but also dry weather. AC environments may be suitably cool and dry. The cutoff is 50% humidity. I keep an open mind on all of these factors along with the response, both from the government and from the people changing their habits. Those can outsmart the virus.
