After seeing only four positive coronavirus cases all summer, Yellowstone National Park employees have seen an uptick in positive virus cases over the last month.
In September, 16 Yellowstone employees, 0.8% of the entire personnel at the park, tested positive for the coronavirus, according to an announcement from the park.
This includes seven National Park Service employees and nine concession workers. Eight of the 16 individuals have recovered and the other eight are in recovery.
All employees who have tested positive have been isolated per the Centers for Disease Control and Prevention and county public health guidelines.
In partnership with Montana and Wyoming, the park has substantially increased employee surveillance testing and has conducted more than 1,100 tests since the first week of September. More than 3,000 tests have been conducted since the park reopened in May.
Contact tracing has occurred with the assistance of Park County, Montana and Park County, Wyoming.
The park only had four positive employee cases between May 18 and Aug. 30.
