I obviously prefer statistics over anecdotal evidence. My 32 year old kid in Texas had it and it was far from asymptomatic.
That's an anecdote. I still don't really understand what is happening with this disease. You can point to Florida as a disaster, and it appeared to be along with AZ and GA and whatever else, and then rather mysteriously the case rate went down. A lot. Maybe this is due to folks getting scared and being more cautious, maybe.
Italy appears to be starting a new rise in reported cases that is significant. That had been lagging a bit as France and Spain took off. They are nearing their peak new reported case rate from April, which was very bad.
France is at three times it's max in April now, over 20,000 new cases per day. Deaths remain low, which is obviously a sign our treatments have improved, or older folks are more protected, but this thing is nearing crisis mode in France. Sweden is also picking up again, around 700 cases per day.
I don't see much correlation between behaviors and case rates, but it's possible that is the explanation.
I also am not sure what public health steps should be taken NOW to limit this disease beyond what we're doing.
