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.
SARs ran like mad in HK and Singapore because they’re air conditioned societies.
It will likely be no different here with this virus.
I have read reports that plaxinel helps therapeutically the virus.
Genetics is more of a factor.
The Chinese have more of the ACE2 enzyme in their lungs than others do. SARS and Covid-19 bind to it. This is likely the reason that both diseases have been big killers in China but not as much elsewhere.
