Michigan: Cases

Total number of confirmed plus probable cases of COVID-19 reported by the state or territory, ideally per the August 5, 2020 CSTE case definition. Some states are following the older April 5th, 2020 CSTE case definition or using their own custom definitions. Not all states and territories report probable cases. If a state is not reporting probable cases, this field will just represent confirmed cases.

The daily increase in API field positive, which measures Cases (confirmed plus probable) calculated based on the previous day’s value.

Total number of unique people with a positive PCR or other approved nucleic acid amplification test (NAAT), as reported by the state or territory. This is equivalent to a confirmed case as per the CSTE case definitions of August 5th, 2020 and April 5th, 2020. If we discover a jurisdiction is labeling cases as confirmed using other evidence (e.g. positive antigen tests), we will annotate that state or territory’s data accordingly.

Total number of probable cases of COVID-19 as reported by the state or territory, ideally per the August 5, 2020 CSTE case definition. By this definition, a probable case is someone who tests positive via antigen without a positive PCR or other approved nucleic acid amplification test (NAAT), someone with clinical and epidemiological evidence of COVID-19 infection with no confirmatory laboratory testing performed for SARS-CoV-2, or someone with COVID-19 listed on their death certificate with no confirmatory laboratory testing performed for SARS-CoV-2. Some states are following the older April 5th, 2020 CSTE case definition or using their own custom definitions.
