Not sure about that. Outside temperature above 37 were common in many highly populated areas, even before "high temperature summer" (e.g., India, Indonesia, most of Brazil, etc.). If there was an actual selection pressure, we would have seen its results by now.

We have already seen selection pressure results in Candida auris

Have we not?

> there are many fungal infections that occur more frequently in tropical zones or are restricted to certain regions within the tropics [0]

I worry that one of the large variety of fungal species not resistant to high temperature will evolve to be resistant and cause great harm to our society. Similar to the way animal spillover events, like covid-19, are so devastating. A novel pathogen introduced to a naive population.

Would a daily peak above 37C counts for the parents point? It has to be longer term temperature I imagine.
