This dashboard is your one-stop shop for up-to-date, Clay County data regarding COVID-19 cases and testing. It includes cases by city, zip code, age, sex and race. Also find the daily tracker, isolation statuses, testing data and more.

Residents of Kansas City - even those that live in Clay County - are reported under the Kansas City, Missouri Health Department. Some KCMO data is included on the Clay County dashboard to provide a clearer picture of Clay County as a whole. 

All sections of the dashboard indicate whether they include KCMO residents or not so please read carefully. "Clay County Public Health Center Jurisdiction" means the data does not include KCMO residents but does include residents of Gladstone, Excelsior Springs, Kearney, Liberty, North Kansas City, Smithville, and other Clay Counties cities and areas.

Contact Tracing

COVID-19 is one of many diseases in Missouri that must be reported to the local public heath department upon discovery or suspicion. When notified that someone who lives in our jurisdiction is infected with one of these diseases, the Clay County Public Health Center epidemiology staff works hard to do contact tracing.

Contact tracing involves a staff member talking with the person who, in this case, tests positive for COVID-19. They talk about who the person may have come into close contact with while infectious and if there were precautions taken that could have prevented spreading the disease to others.

Anyone who is identified as a close contact is:
  • Called by public health
  • Notified of their potential exposure
  • Asked to monitor their symptoms in case they become ill
  • Given any additional guidance and support they need
All identifying information shared with staff remains strictly confidential and used only for purposes of disease tracking. When patients and close contacts cooperate with public health staff during contact tracing, it can make a big difference in slowing the spread of COVID-19. It also increases the accuracy of the local data reported through platforms like the Clay County Dashboard.

When data is more accurate, officials can make better and more informed decisions. For public health, this means we can more accurately predict when it is safe to move forward into another recovery step or, if necessary, put stay-at-home measures back in place.
