After two years of COVID-19 tracking work, I have decided to end my project. Data collection is now frozen at 2022-03-31. This change does not reflect an assessment that COVID-19 is now behind us. On the contrary, I remain very concerned about the risk that new variants pose. However, changes that DHSS has made to their reporting posture have made continuing my work far more challenging. I had initially planned to end the project on 2022-05-09. DHSS’s new dashboard will continue to be a resource for the state but has greatly complicated the process I go through to update my own data.

I will be gradually transitioning some elements of this site to an archive of Missouri’s COVID-19 data over the next six weeks, so you may notice some changes if you return. However, I do not plan to update the underlying data sources again. Thank you so much to those of you who became regular visitors over the last two years. It’s been an absolute privilege to help my neighbors navigate the first two years of the pandemic. Be well! -Chris

Welcome to Chris Prener’s tracking site for the SARS-CoV-2 pandemic in Missouri. This site was updated nightly using data from a variety of federal, state, and local data sources as well as the New York Times’ COVID-19 Project. If you are new to the site, please read the About page for an overview of these data.


Initiated means individuals have received an initial dose of the Moderna or Pfizer vaccines, or the single dose of the Johnson & Johnson vaccine. Completed means individuals have received both doses of the Moderna or Pfizer vaccines, or the single dose of the Johnson & Johnson vaccine.

Additional vaccination maps, plots, and data about Missouri is available on our dedicated page.

Daily Data

While the City of St. Louis, St. Louis County, and Kansas City provide day-by-day tracking of cumulative cases on their respective dashboards, the State of Missouri does not. The following tabs provide daily breakdowns of COVID data as well as additional statistics not included in the existing dashboards. Data are also provided for the wider St. Louis and Kansas City metro areas. Please note that the two average columns for reported cases and deaths are both seven-day rolling averages.

  • The underlying data for these maps are available from GitHub in the county_full.csv, metro_full.csv, and state_full.csv tables, which are assembled from data provided by the New York Times.
  • The FAQ contains a short explanation of per-capita rates.
  • All averages presented are 7-day rolling averages.

Infection Rates by County

This map shows infections as a rate per 1,000 residents. It is important not to map the raw counts themselves, but if you want to see those data, click on a county.
