DID LESTER HOLT REVEAL ANOTHER ANOMALY?

On Wednesday, one of the stories on NBC's nightly news was a short report on Santa Clara County, California's first coronavirus death.  A woman passed on February 6, and that has alerted researchers to the reality of the virus spreading long before the St. Patrick's Day shutdowns became a thing.

Mr Holt concluded his segment (it's not available as a separate clip within the April 22 archive but a variation is here) with an attempt at happy talk, something like the Bay Area "dodged a bullet" as the Kansas City comeback in the February 2 Super Bowl precluded any sort of mass gatherings that week for a victory parade.

The anomaly, though, might be this: suppose the Wuhan coronavirus is getting established in Santa Clara County, which is where the 'Niners' stadium is (a light rail line goes right past it); then the 'Niners and their fans go to Miami, where 'Niners fans talk smack with Chiefs fans in bars and at the stadium, and then the Chiefs and their fans go back to Kansas City for their victory parade.  As of six days ago, Florida experts were reporting evidence of cases at the end of February.  "The flu season had petered off in mid-February as it usually does, according to data from the Florida Department of Health. Deaths from flu and pneumonia peaked the week of Feb. 9, when 260 people died, according to data from the Centers for Disease Control and Prevention." Then came a surge of cases that peaked by the Ides of March.  In the Kansas City area, as of late February, local officials were making preparations, but behaving as if this was something yet to come.  How much of what Miami and Dade counties are seeing might have come from California, or was the absence of any (at least, based on current reporting) community spread from Miami to Kansas City a data point in understanding the contagion?
