The federal government is warning pregnant women to avoid traveling to a stretch of Miami Beach where the Zika virus is spreading.
The Centers for Disease Control and Prevention updated its travel advisory on Friday after news broke that five people got Zika locally in Miami Beach. The CDC already has a travel advisory for a one-square-mile area of the Miami neighborhood of Wynwood, where Zika has been spreading.
Florida Gov. Rick Scott told reporters that the new area is a one-and-a-half mile part of the popular tourist destination.
Zika causes a mild illness and is linked to the birth defect microcephaly, hence the warning for pregnant women.
Pregnant women and their partners who live in the Miami Beach area where Zika is spreading should follow steps to prevent mosquito bites, the agency said.
The CDC added that more cases are expected. Florida officials have found 36 cases of local transmission, likely through misquito bites, the virus' primary mode of transmission.
"We're in the midst of mosquito season and expect more Zika infections in the days and months to come," CDC Director Tom Frieden said. "Florida and Miami-Dade County are taking appropriate steps to control mosquitoes and protect pregnant women. It is difficult to predict how long active transmission will continue."
