Could it be that all of the precautions worked?
If you look at the CDC plot of influenza, it looked very scary at the beginning, with H1N1 cropping up in significant strength at a time when flu is mild, just like the 1918 flu. “The Experts” were extremely worried and blew the siren and started the Drudge flashing light. Many took it seriously. It was an anomalous pattern involving a zoonosis that crossed over.
It turned out not to be a big deal, but the actual incidence could have been steeply reduced by bathing the USA (and other nations) in hand sanitizer and elbow coughs.
BTW my Purell stock did nicely. My Jimmy Dean stock, not so good.
LOL! I haven't thought of ole Jimmy Dean in a long while.
