A group of three Georgetown firefighters are in quarantine at the Georgetown Parks and Recreation Tennis Center after exposure to a known coronavirus patient.

The tennis center is serving as the city’s quarantine area; the facility is closed, and there is no additional public health risk in that area, city officials said in a Facebook post.

The firefighters were informed on the evening of March 27 that they needed to quarantine and to self-monitor themselves for symptoms of the virus, Georgetown Fire Department Chief John Sullivan said to Community Impact Newspaper.

“None of the firefighters, then or now, have exhibited COVID-19 symptoms, as such they are in quarantine and not isolation,” Sullivan said. “It is important to note that there is a clear distinction between quarantine and isolation. The term quarantine is used when a person does not show symptoms but was exposed to an infected patient. Isolation occurs when a person shows symptoms of the virus.”

The firefighters will be in quarantine for 14 days and will receive a coronavirus test if they show symptoms of the virus—including fever, cough and sore throat, Sullivan said. The firefighters have been able to communicate with their families during the quarantine period.
