Oropouche virus is spread to people primarily by the bite of infected biting midges (commonly known as no-see-ums). Some mosquitoes can also spread the virus. Oropouche virus has been found in South America, Central America, and the Caribbean and you may be at risk when traveling to these destinations. Common symptoms include fever, severe headache, chills, muscle aches, and joint pains. The symptoms of Oropouche may be confused with other travel-associated illnesses, like dengue, chikungunya, or Zika. Most people will recover within several days to one month.
There are no vaccines or specific medicines for Oropouche. The best way to protect yourself is to prevent bites from biting midges and mosquitoes. To prevent insect bites, use an Environmental Protection Agency (EPA)-registered insect repellent, wear long-sleeved shirts and pants, and stay in places with air conditioning when possible. Make sure the insect repellent is labeled for use against flies, biting flies, or Culicoides (biting midges, punkies, granny nippers, and no-see-ums). While window and door screens can prevent mosquito bites, standard screens may not protect against midge bites.
CDC is working with international partners to learn more about the risks of Oropouche virus infection during pregnancy. Pregnant travelers should review travel alerts for their destination and talk to their healthcare provider about travel plans, potential risks, and steps to prevent insect bites.
