The Florida Keys will be temporarily closed to visitors starting at 6 p.m. ET Sunday, a press release from officials said.
Hotels and other lodging properties on the Keys have been ordered to closed, the release said.
The first case on the island chain was announced Thursday and spurred the decision to close to visitors, the release said.
“We understand that this is a tremendous inconvenience to our visitors as well as to our businesses, and more than an inconvenience to our workers — our families who live here,” said Monroe County Mayor Heather Carruthers in the release. “But the health and safety of both our visitors and our residents is paramount.”
