A COVID-19 case is an individual who has been determined to have COVID-19 using a set of criteria known as a case definition. Cases can be classified as suspect, probable, or confirmed. CDC counts include probable and confirmed cases and deaths. Suspect cases and deaths are excluded. The case classifications for COVID-19 are described in an updated interim COVID-19 position statement and case definition issued by the Council of State and Territorial Epidemiologists. A probable case or death is defined as any one of the following: Meets clinical criteria AND epidemiologic linkage with no confirmatory laboratory testing performed for SARS-CoV-2 Meets presumptive laboratory evidence Meets vital records criteria with no confirmatory laboratory evidence for SARS-CoV-2 Any cases and deaths classified as probable are included in CDC case counts. The same applies to any cases and deaths classified as confirmed.
