MIAMI (WCTV) – Florida health officials are reporting the state’s first sexually transmitted case of Zika in 2017.

According to a Florida Department of Health statement, the partner of a Pinellas County resident showed symptoms of the mosquito-borne virus after the resident returned home from a trip to Cuba.

Officials said both patients tested positive for Zika.

Zika can cause a mild illness, with symptoms including fever, rash and joint pain. Infection during pregnancy can lead to severe brain-related birth defects.

The health department said there’s no evidence of mosquitoes transmitting Zika anywhere in Florida. Most of Florida’s 118 Zika cases this year have been linked to travel outside the continental U.S.
