Four new Zika cases in Florida have brought Florida’s total to 66, the state’s health department reported Friday.

Three of the new cases occurred in Alachua County, and one in Brevard County. Of the 66 cases confirmed in Florida, seven cases are still exhibiting symptoms.

The highest number of cases occurred in Miami-Dade County, with two more cases confirmed earlier this week, which brings the total to 30.

The number of Zika cases in Florida remains the highest in the country, with Texas ranked second at 34. California is third with 13 cases, with the remaining states reporting numbers in the single digits.

Four of Florida’s 66 cases are pregnant women, which were previously reported.  The Zika has been linked to birth defects in babies as well as possibly to brain infection in adults.

All cases of the mosquito-borne virus in the U.S. stem from travel either to the Caribbean or South America, where there have been thousands of cases of the disease.
