Influenza and COVID-19 pose major risks to our health and wellbeing. We've created a system that allows citizen scientists, like you, across North America to securely and anonymously self-report symptoms.
And since our users generally report before they see a healthcare provider, we can see trends and the spread before local and national public health agencies.
Contribute your health status
If you’re living in North America, log on and let us know how you’re feeling one or more times per week.
See the impact on your community
Check out if others in your community are reporting early warning signs of a COVID-19 or influenza outbreak.
CDC and others analyze data
CDC and local public health agencies analyze the data for potential outbreaks and help predicate where COVID-19 and the flu might impact next.
