About HealthWeather™

Overview and Methods

HealthWeather™ 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 accompanying mobile applications, and Kinsa is providing this map and associated charts as a public service.

HealthWeather was launched on March 18 and announced in The New York Times and on The Rachel Maddow Show.

For answers to common questions about the map and the terms used here, please review our FAQ page. For details about our approach to determining typical and atypical illness levels, please review our technical approach document.

Please read a note from our founder and CEO.

Suggested Uses

For public health officials, and anyone dealing with the COVID-19 pandemic response in a professional sense, we suggest using this data in the following two ways:

  • Identify areas where illness levels are unusually high, and investigate: we suspect that areas with illness levels that are higher than expected are likely to be early indicators of community spread of COVID-19. This is best seen in the “Atypical” mode of the map visualization above.
  • Gauge whether measures taken are working to slow the spread: as social distancing, school closures, and similar measures start to take effect, we expect influenza-like illness levels to drop — if illness levels are dropping, the measures are working. This is best seen in the “Trend” mode of the map visualization above.

Created in collaboration with Benjamin Dalziel, Oregon State University.
