Big Horn County reported five new cases of COVID-19 Wednesday afternoon.
Two of the cases were symptomatic, and the remaining three tested positive at surveillance testing events held May 27 and 28 in Crow Agency and Hardin, Health Officer Rhonda Johnson said in a news release.
The new cases are two men in their 50s, a woman in her 70s and two men in their 70s.
Big Horn County now has 36 total cases. Eight people have recovered, and 28 cases are active.
Big Horn has the most active COVID-19 cases in the state.
The new cases bring the total in Montana to 530 but have not been added to the state's map. The state has 49 active cases, and 469 people have recovered.
MTN is reporting one fewer total case and one fewer recovered case due to a case in Jefferson County that local health authorities report involved a patient who was not in the state.
