*updated August 11, 2021* With the Delta variant skyrocketing in Missouri, this page will continually be updated to reflect the latest mask mandates.
The coronavirus global pandemic has transformed the way we live our lives, making social distancing, working from home, and wearing a mask the norm.
According to the CDC, wearing a mask out in public can protect you and your community by preventing COVID-19 respiratory droplets from traveling into the air and infecting others – especially if you’re not fully vaccinated.
So what are the mask requirements in the state of Missouri? The answer depends on where you live.
Missouri Governor Mike Parson has not issued a statewide mask mandate and left the decision to issue ordinances requiring face coverings up to local governments.
On July 27, 2021, the CDC reversed its May guidelines, stating both vaccinated and unvaccinated individuals should wear a mask indoors in areas with high transmission.
Below is a comprehensive list of mask mandates across Missouri as of August 11, 2021.
Note that ordinances can be issued by either a city or county, so it’s best to check both. For example, St. Louis County’s ordinance applies to all 88 municipalities within the county.
