This coronavirus map shows the estimated percentage of people who may have experienced symptoms in a week by county. 

About this map

This map shows the estimated percentage of people who may have experienced symptoms based on a 3-day rolling average by Hospital Referral Region.

Hospital Referral Regions (HRRs) represent regional health care provider markets with at least one hospital that conducts specialized medical care, such as major cardiovascular procedures or neurosurgery. HRRs are not associated with specific counties.

This map uses symptoms from the CMU survey as follows:

  • COVID-19 symptoms include a fever and either a cough, shortness of breath or difficulty breathing.
  • Flu symptoms include a fever and either a sore throat or cough.
