The CDC continues its work in Missouri to help local K-12 schools and public health leaders review current COVID-19 measures. Schools participating in the first-of-its-kind pilot project are being identified in St. Charles, St. Louis, and Greene Counties. During a Missouri Board of Education meeting this week, State Department of Elementary and Secondary Education spokeswoman Mallory McGowin says the project is being piloted for the next couple of weeks until schools go on winter break.

The effort will track COVID-19 infections among students and staff based upon whether they were wearing masks in school when they came into close contact with someone infected with the virus. Participation is voluntary.
