The St. Louis County Department of Health issued an advisory Monday evening urging anyone who recently ignored social distancing guidelines while they visited the Ozarks to self-quarantine for 14 days or until they test negative for coronavirus. On Tuesday, the Kansas Department of Health and Environment also recommended a two-week self-quarantine for those travelers.

The order is a result of reports of huge crowds partying in pools and other locations in the area during the long weekend. Many of the partygoers did not wear masks and were seen close to each other in photos and videos that went viral.

St. Louis County Executive Sam Page said he is concerned these revelers could pose a danger when they return to their homes and workplaces.
