I think one of the worst things about COVID-19 is that it probably isn’t seasonal which means no relief from it. I hope it subsides as we head into spring and summer, but I wouldn’t bet on it.
I would argue that something that is speculative cannot be “the worst thing”, saying “the worst thing about” suggests that the speculation is a known fact.
on the contrary, looking at current infections, it appears that this virus IS impacted by warm weather, and it would be surprising if it wasn’t. Hardly any cases in the southern hemisphere, and some of those are people who traveled to places where the virus was. And the philipines, which had a real outbreak, doesn’t seem to have nearly the spread that we see in other places.
Note that A/C puts lots of people inside buildings where spread can happen, so just having “high heat” outdoors is not salvation.
