Look at the three states that have big increases since May. AZ, TX, and Fl. Places where it's either 108 or high 90's with high humidity. People that are indoors out of the heat going or staying in ventilated areas with AC. I think we don't know the spread of this virus inside that created big problems early on with the elderly in homes. Kids didn't get it because schools closed quickly. What we have know are the younger generation out and about going on living, bars, parties, and hanging at malls. With summer starting weeks ago and temps ranging higher cases up in 40 states now. Keeping casinos open and people inside doesn't make sense. I think the other issue to go with ventilation that the mask DON'T work unless it's the N95 mask. The other mask and bandanas don't help keep the micro particles entering through the mask.
