This month, Florida has begun to see an alarming number of homegrown cases of Zika; that is, non-travel related cases, which were the biggest worry some months ago. So far, Florida is the only US state to have local transmission of the virus.
As of August 24, there are now 43 local cases of Zika infection, with outbreaks occuring in Miami and Miami Beach. The number of travel-related cases in Florida is 523, and 70 of whom are pregnant.
With Florida's warm, humid climate, it's the ideal location for Aedes mosquitoes to thrive and spread the virus. But with so many locally transmitted cases appearing in such a short time, the Department of Health in Florida are understandably worried.
