Three visitors and two concessions employees at Yellowstone National Park have tested positive for COVID-19, the park reported on Tuesday.
"Some of these visitor cases had symptoms prior to entering the park," Superintendent Cam Sholly said in a statement. "If you have symptoms as your visit is approaching, do the responsible thing and don't come to the park. You end up putting our employees, health care providers, and other visitors at risk."
