Case data

Information about positive tests in Boone County

Columbia/Boone County Health and Human Services is the official source for information about COVID-19 cases in Columbia.

  • The data on this page are provided to the university by Columbia/Boone County Health and Human Services.
  • Because students, faculty and staff can seek testing from a variety of medical providers in and outside of the county, student case numbers provided to MU are incomplete.
  • Students are identified by Boone County when they test positive. Therefore, the county and MU have no way of knowing how many students are tested.
  • Boone County health officials are tracking the numbers of MU students who test positive in the county. Cases of COVID-19 confirmed in other counties and the identities of those who test positive are confidential.
  • Faculty and staff cases at MU are based on self-reports made to supervisors, and are not tracked specially by Boone County. These data are shared in aggregate.
  • Data below are based on cases tested and confirmed at the MU Student Health Center and other testing locations in Boone County since Aug. 19, as identified by Boone County and shared with the university.

MU has requested all students, faculty and staff self-report positive cases to the university so resources and accommodations for remote learning or work can be made available. Information about individuals who test positive will be kept confidential.

Contact tracers will identify close contacts and provide guidance

Boone County health officials will direct contact tracing of every positive case in the county to ensure that close contacts of those with positive cases are identified and receive directions for next steps. Close contacts will not be informed of the name or any other identifying information of the person who potentially exposed them due to federal privacy laws.

Information about specific cases will not be shared

Federal privacy laws prohibit the university from disclosing individual identities and any personally identifying information of individuals who test positive. If you are made aware of someone who has tested positive for COVID-19, you must not share that information.

The individual who tested positive will be isolated, a case investigator will identify close contacts, and contact tracers will contact close contacts and advise them on quarantine.
