From healthweather.us:
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.
The map shows two key data points: (1) the illness levels we’re currently observing, and (2) the degree to which those levels are higher than the typical levels we expect to see at this point in the flu season. We believe this latter data point — which we’re calling “atypical illness”, may in some cases be connected to the COVID-19 pandemic.
Please note: We are not stating that this data represents COVID-19 activity. However, we would expect to pick up higher-than-anticipated levels of flu-like symptoms in our data in areas where the pandemic is affecting large numbers of people. Taken together with other data points, we believe this data may be a helpful early indicator of where and how quickly the virus is spreading.
