About the Data on This Page

  1. State health departments report the level of community transmission (spread) of COVID-19 as one of the following:
    • Yes, widespread – defined as widespread community transmission across several geographical areas
    • Yes, defined area(s) – defined as distinct clusters of cases in a, or a few, defined geographical area(s)
    • Undetermined – defined as 1 or more cases but not classified as “Yes” to community transmission
    • No cases reported (previously presented as “N/A”) – defined as no cases
  2. CDC is no longer reporting the total number of persons under investigation (PUIs) tested and the number of PUIs who tested negative. CDC’s numbers do not represent all testing in the U.S. now that U.S. states and territories are testing and reporting their COVID-19 cases.
  3. “Diamond Princess” Cruise Ship cases are confirmed by laboratory tests. These people might not have shown symptoms.
  4. On March 24, 2020, CDC updated the data included in this figure to include estimated illness onset date.
