"But the consistent and rapid decline in daily cases since Jan. 8 can be explained only by natural immunity."

 

I find that statement puzzling.  Infections peaked and began to decline after holiday travel ended.  That can be explained by far fewer people engaging in high risk social activities after the first of the year.  The 77% decline has us back to the weekly infection rate of October, which was pretty high.  https://covid.cdc.gov/covid-data-tracker/#trends_dailytrendscases

 

I'll be happy if herd immunity is kicking in this early, but I'll keep masking and social distancing until the numbers come down further and more doctors and scientist agree the threat has passed.
