The 74 cases had been reported as of Monday and were an increase of two cases from a week earlier.
Other counties with reported cases have been Broward, Palm Beach, Lee, Osceola, Hillsborough, Pinellas, Hernando and Walton.
The department website said 72 of the cases are classified as “travel related”
- generally meaning people were infected with the virus elsewhere and brought it into the state. The other two cases were classified as having “undetermined” origin. Both of the “undetermined” cases involved people in Miami-Dade County.
The disease, which caused major concerns in 2016, is particularly dangerous to pregnant women because it can cause severe birth defects.
