Florida health officials on Monday reported one more locally acquired Zika infection in a person who felt no symptoms but who was tested for the virus in February.
The person likely acquired Zika in Miami-Dade in 2016 after “multiple exposures” to areas where mosquitoes were spreading the virus, the Florida Department of Health reported, adding that the state had just received confirmation from the federal Centers for Disease Control and Prevention.
In addition, Florida reported four new travel-related Zika infections, raising the total number of cases for 2017 to 29 people, including one locally acquired case from Miami-Dade. Among the 29 cases reported in Florida this year are 13 pregnant women and two people whose source of infection is undetermined after a health department investigation.
Pregnant women are considered to be at the greatest risk from Zika because the virus has been shown to cause microcephaly and other neurological disorders in children born to mothers infected while pregnant. The frequency of Zika infections in Florida has declined over the winter, but public health experts expect the virus to resurface as the temperature warms and rain increases.
