Cases in the U.S.

CDC has moved the following information to the Previous U.S. COVID-19 Case Data

• When did people in the U.S. get sick from COVID-19,
• How did people in the U.S. get COVID-19, and
• Cases of COVID-19 from Wuhan, China and the Diamond Princess cruise.

Updated Daily

This page is updated daily based on data confirmed at 4:00pm ET the day before.

Numbers reported on Saturdays and Sundays are preliminary and not yet confirmed by state and territorial health departments. These numbers may be modified when numbers are updated on Mondays.

Number of Jurisdictions

There are currently 55 U.S.-affiliated jurisdictions reporting cases of COVID-19. This includes 50 states, District of Columbia, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S Virgin Islands.

Confirmed & Probable Cases

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 statement pdf iconexternal iconissued 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 one of the following:

• Meeting clinical criteria AND epidemiologic evidence with no confirmatory laboratory testing performed for COVID-19
• Meeting presumptive laboratory evidence AND either clinical criteria OR epidemiologic evidence
• Meeting vital records criteria with no confirmatory laboratory testing performed for COVID19

Community Transmission

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
• “N/A” – defined as no cases

Case Notifications

Case notifications were received by CDC from U.S. public health jurisdictions and the National Notifiable Diseases Surveillance System (NNDSS).

Accuracy of Data

CDC does not know the exact number of COVID-19 illnesses, hospitalizations, and deaths for a variety of reasons. COVID-19 can cause mild illness, symptoms might not appear immediately, there are delays in reporting and testing, not everyone who is infected gets tested or seeks medical care, and there may be differences in how states and territories confirm numbers in their jurisdictions.

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.
