Florida reports four more cases of local zika infection in miami

(HealthDay)—Four more cases of Zika infection that were likely spread through mosquito bites have been reported in the Miami area, bringing the total count of cases to 21, Florida Gov. Rick Scott said Tuesday.

The Florida Department of Health still believes these infections are only happening within one square mile in Miami-Dade County, in a neighborhood known as Wynwood.

Meanwhile, aerial spraying that began last week rapidly killed adult mosquitoes that ground-applied pesticides could not reach, Tom Frieden, M.D., M.P.H., director of the U.S. Centers for Disease Control and Prevention, told the Associated Press.

In the meantime, the CDC is urging pregnant women and their partners to stay away from Miami's Wynwood neighborhood—the first time the CDC has ever warned against travel to an American neighborhood for fear of an infectious disease. The CDC advises pregnant women not to travel to an area where active Zika transmission is ongoing, and to use insect repellent and wear long pants and long-sleeved shirts if they are in those areas. Partners of pregnant women are advised to use a condom to guard against sexual transmission during pregnancy.
