About the Data on This Page
1. State and local public health departments are now testing and publicly reporting their cases. In the event of a discrepancy between CDC cases and cases reported by state and local public health officials, data reported by states should be considered the most up to date.
2. As of April 14, 2020, CDC case counts and death counts include both confirmed and probable cases and deaths. This change was made to reflect an interim COVID-19 position statementpdf iconexternal icon issued by the Council for State and Territorial Epidemiologists on April 5, 2020. The position statement included a case definition and made COVID-19 a nationally notifiable disease.
A confirmed case or death is defined by meeting confirmatory laboratory evidence for COVID-19. A probable case or death is defined by i) meeting clinical criteria AND epidemiologic evidence with no confirmatory laboratory testing performed for COVID-19; or ii) meeting presumptive laboratory evidence AND either clinical criteria OR epidemiologic evidence; or iii) meeting vital records criteria with no confirmatory laboratory testing performed for COVID19.
3. Self-reported by health department characterizing the level of community transmission in their jurisdiction as: “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); or “N/A” (defined as: no cases).
4. Case notifications were received by CDC from U.S. public health jurisdictions and the National Notifiable Diseases Surveillance System (NNDSS).
