Oropouche and Pregnancy | Oropouche
Oropouche and pregnancy
Oropouche virus is spread to people by the bites from infected biting midges, sometimes called “no-see-ums.” Some mosquitoes can also spread the virus.
The most common symptoms include
- Fever
- Headache
- Chills
- Muscle aches
- Joint pain
Symptoms usually last 2–7 days, but often come back a few days or even weeks later. Most people with Oropouche virus disease (Oropouche) recover within several days to a month. Some people may get very sick with Oropouche. There are no reports of pregnant people getting sicker than others.
What is known about Oropouche during pregnancy
There is little information on Oropouche in pregnancy. Based on a few cases, there are concerns that the Oropouche virus can be passed from a pregnant person to their fetus. This has been linked to poor pregnancy outcomes such as stillbirth and birth defects. CDC is working to understand the potential risks of Oropouche during pregnancy and will share updates as we learn more.
If you get Oropouche during pregnancy
There are no medicines to treat Oropouche or prevent the infection spreading to the fetus.
- Symptoms can be treated by getting rest, drinking fluids to prevent dehydration, and taking over-the-counter pain medicine such as acetaminophen to reduce fever and pain.
- Additional medical care or hospitalization might be needed to manage more severe symptoms.
- Do not take aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs) to reduce the risk of bleeding.
- Talk with your healthcare provider about plans for monitoring your pregnancy and evaluating your infant at birth.
Areas with Oropouche
Oropouche virus has been found in certain countries of South America, Central America, and the Caribbean. In 2024, Bolivia, Brazil, Colombia, Cuba, and Peru have reported outbreaks of Oropouche. Some U.S. travelers who recently returned from Cuba have been diagnosed with Oropouche.
There is currently no identified spread of Oropouche virus in the United States. The likelihood of the virus spreading widely or causing sustained transmission in the continental United States is likely low because of differences in climate, biting midge and mosquito populations, and lifestyles (such as the use of air conditioning). The risk of sustained transmission in Puerto Rico and U.S. Virgin Islands is unknown.
If you are planning travel to an area with Oropouche
There is no vaccine or medicines to prevent or treat Oropouche. Before traveling, pregnant travelers should discuss travel plans and potential risks with their healthcare provider.
Check Travel Health Notices before planning travel
How to prevent bug bites
Reconsider non-essential travel to areas with an Oropouche Level 2 Travel Health Notice.
Protect yourself and your pregnancy if you must travel. Follow these important steps to prevent bug bites during and 3 weeks after your trip:
- Use Environmental Protection Agency (EPA)-registered insect repellents, which are proven safe and effective to use during pregnancy and while breastfeeding.
- Wear long-sleeved shirts and long pants.
- Stay in places with air conditioning or that use window and door screens designed to keep biting midges or mosquitoes outside.
- Many commonly used widow and door screens do not have holes small enough to prevent biting midges from getting inside.
- To prevent biting midges from entering your home, look for screens with mesh screens measuring 20×20.
Testing if you travel to an area with Oropouche
If you get sick with symptoms of Oropouche while traveling or within 2 weeks of returning home:
- Talk with your healthcare provider about where you traveled and your symptoms.
- Your healthcare provider may test you for Oropouche and possibly other diseases that are common where you traveled.
If you did not have symptoms of Oropouche during travel or within 2 weeks of returning home:
- Oropouche testing is not recommended at this time.
- Tell your healthcare provider where you have traveled during your next scheduled prenatal check-up.
- Stillbirth and birth defects have only been associated with Oropouche infection in people who were sick around the time of travel.
Breastfeeding
At this time, there are no reports of Oropouche virus being spread through breastfeeding. Because of the many benefits of breastfeeding
- Mothers are encouraged to breastfeed, even if they were diagnosed with Oropouche or lived or traveled to an area with Oropouche.
- It is important to take steps to prevent bug bites as noted above. EPA-registered insect repellents when used as directed are safe and effective for breastfeeding women.
