More than 40 Florida Highway Patrol employees are self-isolating because of exposure to the novel coronavirus, including three state troopers who tested positive for COVID-19, a spokesman confirmed to The News Service of Florida.

Employees have self-isolated after coming into close contact with people who tested positive for COVID-19, the contagious respiratory disease caused by the coronavirus. Others have self-isolated because they traveled to virus hot spots or were exposed to people who traveled to those areas.

The News Service reported on Tuesday that the three troopers had tested positive.
