Florida health officials confirmed two new Zika virus infections in Miami-Dade on Tuesday, raising the county’s total to 30 people who have contracted the infectious disease — the greatest number of cases in the state.
Statewide, a total of 62 people have contracted the Zika virus, including eight in Broward County, since Florida’s Department of Health began reporting infections on Feb. 9.

Pregnant women are at greatest risk because of recent findings establishing a link between an outbreak of Zika in Brazil and a concurrent spike in microcephaly, a birth defect in which a baby is born with an abnormally small head and an underdeveloped brain.
So far, all but one case of sexual transmission in Polk County were acquired by travelers outside the state, the health department reported.
The federal Centers for Disease Control and Prevention reports that between Jan. 1 and March 9 there were 193 reported cases of Zika virus in the U.S.
Zika is primarily transmitted by Aedes aegypti mosquito bites, although the spread of the virus also has been reported through blood transfusions and by men to their sexual partners.
