Zika virus infections in Florida increased to 18 on Thursday, marking the first increase in three days, with the highest number reported among residents of Miami-Dade, where seven cases have been confirmed, the Department of Health said.
All of the Zika cases were acquired outside of Florida, and none involves pregnant women, who are considered to be at greatest risk from the virus because of its suspected association with birth defects and neurological disorders.
On Feb. 3, Florida Surgeon General John Armstrong declared a public health emergency for the seven counties with confirmed cases of Zika, including Broward, Hillsborough, Lee, Miami-Dade, Osceola, Santa Rosa and St. Johns.
Warnings followed the rapid spread of Zika throughout South America and the Caribbean beginning in 2015, which led the World Health Organization to declare a global emergency on Feb. 1.
