The U.S. Health Weather Map is a visualization of seasonal illness linked to fever - specifically influenza-like illness. The aggregate, anonymized data visualized here is a product of Kinsa’s network of Smart Thermometers and the accompanying mobile applications. Kinsa is providing this map and associated charts as a public service.
As of March 22nd Florida is showing a ton of red, indicating 3% more fevers than expected based on Kinsa's models for a typical flu season. Between data like this, minimal social distancing policies up to this point, and the demographics of the state, I think Florida is a ticking Covid-19 timebomb.
