In my country, it is only possible to be tested if you say you were in direct contact with the current 4 confirmed cases (1 deceased), and they would have to confirm that too.
These places are not buried in dead people either. Their intensive care systems are not being flooded. Their hospitals are not being flooded by a million cases.
Mexico is not seeing what NY and other high-infection climates have. Given the poverty, poor healthcare system, poorly prepared healthcare system, high traffic and trade with the US via NAFTA and in general, it should have an enormous number of cases by now, and as a consequence a large number of daily deaths and intensive care cases hammering their healthcare systems in every major city. None of that is happening. It's not happening for the same reason it's not happening in Texas.
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.
