Britain Warns Fla Tourists: No Sex with Zika

British officials are urgeing travelers to Florida to avoid unprotected sex for the remainder of the summer over concerns of spreading the Zika virus, The Telegraph reports.

British health officials have urged pregnant women to consider postponing non-essential travel to Florida after the southern U.S. state confirmed the first cases of the Zika virus that were not linked to travel.\

But anyone already on holiday in Florida should avoid unprotected sex for at eight weeks, officials said. About 50,000 British citizens are believed to currently be vacationing in Florida

The Sunshine State, a popular holiday destination for Britons, reported four cases of local transmission on Friday. Officials said that those infected had probably been bitten by a mosquito, and said they suspected the cases originated in a one-square-mile area north of downtown Miami.

"Pregnant women should consider postponing non-essential travel to affected areas until after the pregnancy," Public Health England, the government's public health agency, said. It said the risk in Florida from Zika was considered moderate based on the number and spread of cases.

The current outbreak of the Zika virus was first detected in Brazil last year and has since spread rapidly through the Americas. It can cause birth defects including serious brain abnormalities.
