The CDC Has Issued a Travel Advisory for a Zika Virus-stricken Area of Miami

"We do expect additional infections to be reported," said CDC director Tom Frieden.

After 10 more cases of Zika virus were confirmed in Florida, the U.S. Centers for Disease Control and Prevention issued a travel recommendation that pregnant women do not go to the one-square-mile patch north of Miami’s downtown where the cases were detected.

The CDC also said that women who have been in the area should wait at least eight weeks before trying for a pregnancy.

The new cases bring the state’s total to 14, a major worry for a state whose top industry is tourism. “We do expect additional infections to be reported,” said CDC director Tom Frieden.

Florida’s governor, Rick Scott, said the state wants to increase spraying in the area where the cases were detected, home to a popular tourist attraction: the colorful Wynwood Walls.

Scott tried to assuage fears that Florida may be unsafe for tourists due to the outbreak.

At stake is Florida’s $67 billion-a-year tourism industry. Already, international governments are warning travelers who are pregnant or thinking about becoming pregnant to avoid essential travel.

On Friday (July 29), Florida’s Department of Health reported the first four locally-transmitted cases. The disease, which can cause severe fetal brain defects, such as microcephaly, has been mostly spread through infected mosquitos.
