Real-time temperature monitoring in the US - Kinsa Health (Bluetooth connected thermometers allows for real-time national fever monitoring. They have a cool heat map (https://healthweather.us/) of current fever levels. The heat map below shows 'atypical' fever in US on March 24, 2020.

Note: Due to widespread social distancing, school closures, stay-at-home orders, etc. feverish illness levels are dropping in many regions. This does not mean that COVID-19 cases are declining. In fact, we expect to see reported cases continue to surge in the near term, but it may indicate these measures are starting to slow the spread.

Looks like they updated the message on their site. Previously it just said something about how atypical illness had dropped to expected levels.

Interesting that they think the measures are starting to slow the spread based on their data. Part of me just thinks they have insufficient data.
