Another anon dropped a seasonal variations chart of upper respiratory infections from the book The Transmission of Epidemic Influenza by R. Edgar Hope-Simpson.
Interesting, and got this non-medical anon's almonds tingling.
Today, the CDC released an update of additional Covid-19 symptoms.

Did a little digging to see if there was a connection between China Flu round one and round two.
We keep being told the virus is mutating, it's not as strong, etc.
Could round two be the Enterovirus, which annually impacts 30 - 50 million usually in the Summer and Fall?
