The Centers for Disease Control and Prevention is advising travelers to take steps to protect against the spread of the Zika virus as more than 50 states and the District of Columbia have passed laws to restrict travel and restrict travel to places with Zika outbreaks.
Travelers can’t use their credit cards, buy alcohol or rent or buy food at retail locations where Zika is currently circulating, or buy or sell any drugs from overseas, according to the CDC’s guidelines.
The CDC is also warning people not to use their mobile phones or computers to communicate with people who are pregnant or are at risk for infection.
The recommendations also apply to people traveling through Mexico.
The agency is urging people to wear gloves and goggles while traveling and to avoid using any disinfectant that can be spread through the air.
The U.S. has been one of the hardest hit countries, with nearly 5,300 confirmed cases and 1,700 deaths.
The CDC recommends people who have recently traveled overseas to contact their host country’s health department and report any signs of Zika.
They also can call the U.N. refugee agency and ask them to provide support and advice.
The virus has been spreading in Europe since March, but the first confirmed cases have been reported in the United States.
The virus has already infected more than 1.5 million people worldwide.
