A new study from Harvard indicates that warmer weather and more humidity and UV exposure will only modestly slow down the spread of the virus. It all depends on the R value, the average number of people a infected person will pass on the disease to others, if it's less than 1 the virus will eventually die out. In Wuhan in the very early days of the epidemic before any social distancing took effect R was found to be about 3.5. And this new study suggests that the summer weather will likely reduce R by 43%, and that means R would still be way larger than 1. So that does not bode well for the recent rash of reopenings that have been urged by some politicians, by late summer or early fall we should know if this grim prediction was correct.
