Zika is particularly dangerous to pregnant women because it can cause severe birth defects.

The Department of Health said 82 of the 84 cases are considered “travel” related — generally meaning people were infected elsewhere and brought the disease into the state.

The other two cases were classified as having “undetermined” origin, with both of those cases involving people in Miami-Dade County. Orange County has the third-largest number of cases in the state, with 10.
