As of September 2024, Oropouche virus infections have been identified in several people in multiple states within the United States. All cases in the U.S. are linked to international travel.
What symptoms should I watch for?
Symptoms may start sometime between 3 and 10 days after the bite occurs while traveling to an area with Oropouche virus transmission. Abrupt onset of fever with headache, chills, muscle, and joint pain may occur. Pain when looking at bright lights, nausea and vomiting, and rash have also been reported. Symptoms usually last for less than one week. Most people will have recurrent symptoms after initially feeling better.
Rarely, there can also be neurologic symptoms such as eye pain, confusion, dizziness and discomfort or soreness of the neck. About one in twenty people will develop inflammation of the brain or spinal fluid.
How does Oropouche virus impact children?
Children may become ill if bitten by an infected biting midge or mosquito. Infection during pregnancy can lead to birth defects and miscarriages.
How do I protect myself and my family from infection?
Oropouche virus spreads when a person is bitten by an infected midge or mosquito. For this reason, prevention of insect bites in areas with Oropouche transmission is our #1 defense.
If you are pregnant, consider whether travel to an area with Oropouche infection is necessary. Talk to your healthcare provider about possibly postponing your travel.
To prevent insect bites, use insect repellents and wear light-colored long-sleeved shirts and long pants while outside. EPA-registered repellents should be labeled for flies, biting flies, or Culicoides (biting midges, punkies, granny nippers, and no-see-ums). For young children, ensure the specific repellent is safe, as not all repellents are recommended are safe in all age groups. Window and door screens can help prevent midges and mosquitoes from entering your home.
