From everything I've read about COVID-19 and flu-like infections, I'm also inclined to believe that warmer climates help slow COVID-19 outbreaks. It is (in my opinion) the most plausible explanation why certain regions are hit so much worse than others thus far. I also believe a paper I recently read supports this hypothesis.

I've seen the media publish articles with titles like "coronavirus myths busted: warm weather stops the virus". Ironically, these attempts to combat misinformation are dubious themselves, as the truth is probably somewhere in the middle; that is, warm climates may not outright stop COVID-19, but they may certainly hinder it. The fact is, while we can't make definitive statements at the moment due to limited data and understanding of the virus's pathology, we can make educated guesses through observation.

Another contentious point (particularly here in Australia) is the sentiment that children are mostly immune to the virus. The Aus government is pushing this line very strongly as an excuse to keep schools open (i.e. economical reasons).

So yeah, I don't know why I wrote this comment. Probably to stress the fine line that exists between having a mindset which is open to observational theories, while also being critical of "facts" which are pushed to drive political agendas amidst the coronavirus outbreak.
