Data Interpretation Notes

  • Information in these charts is provisional and subject to change. Use care interpreting charts and tables. 
  • Total cases include: Outpatient, Hospitalized, Deceased, and Recovered individuals.
  • Confirmed cases: Individuals who have a PCR positive lab result for COVID-19.
  • Probable cases: Individuals with a positive rapid antigen test conducted in a healthcare setting and no confirmatory testing (PCR or nucleic acid test). A person may also be classified as a probable case if they are a close contact to a case and have symptoms consistent with COVID-19.  Individuals with a positive home antigen test who are symptomatic or linked to another positive case would also be a probable case of COVID (note that most home antigen tests are not reported to public health).
  • Students: College students living locally are included in Washtenaw County case counts.
