TAMPA, Fla. (AP) — Gov. Rick Scott has declared a health emergency in four counties due to the Zika virus.

At least nine cases of the mosquito-borne illness have been detected in Florida. Health officials believe all of the cases are from people who contracted the disease while traveling to affected countries.

Scott signed the order Wednesday to cover Miami-Dade, Lee, Hillsborough and Santa Rosa counties.
