This sheet talks about exposure to Staphylococcus aureus and Staph infections in a pregnancy and while breastfeeding. This information should not take the place of medical care and advice from your healthcare provider.
What is Staphylococcus aureus / a Staph infection?
Staphylococcus aureus (Staph) are a type of bacteria (germ). Staph bacteria are commonly found on the skin or in the nose.
Most of the time, people will not have problems with these bacteria. However, if Staph gets inside the body through a cut or sore, this could lead to a Staph infection. Staph infection can cause boils or blisters on the skin; or infections in the lungs (pneumonia), bloodstream (sepsis), or in a wound.
People with a higher chance of getting a Staph infection include sick people in hospitals, people recovering from surgeries or other medical procedures, people living in over-crowded conditions (shelters or prisons), children in daycare, intravenous (IV) drug users, people with weakened immune systems, people with chronic health conditions (like diabetes or cancer), athletes, and military personnel.
Eating food that has been contaminated with Staph bacteria can also cause food poisoning. Symptoms can be severe vomiting and diarrhea with stomach pain that will start within a few hours after exposure. This type of infection with Staph bacteria usually is not serious and generally does not last for more than a day.
I am pregnant. If my partner, other family member, or friend has a confirmed Staph skin infection, what can I do to reduce my chances of getting the infection?
- Do not touch the person’s sores, cuts, or bandages.
- Wash your hands with soap and water often, and always wash your hands after direct contact with anyone who has any skin infection.
- Do not share towels, soap, razors, tweezers or other personal items.
- If you need to wash the laundry for a person with a Staph infection, launder in warmest temperature recommended by manufacturer’s directions and dry the clothes thoroughly.
I have a Staph infection. Can it make it harder for me to become pregnant?
Based on the available data, it is not known if a Staph infection can make it harder to get pregnant.
Does having/getting a Staph infection increase the chance for miscarriage?
Miscarriage can occur in any pregnancy. Based on the data available, it is not known if a Staph infection might increase the chance of miscarriage.
Does having/getting a Staph infection increase the risk of birth defects?
Every pregnancy starts with a 3-5% chance of having a birth defect. This is called the background risk. Staph infections have not been linked a higher chance for birth defects. However, Staph infections that reach the blood can cause a fever, and fevers of 101 degrees or more might increase the chance for some birth defects. See our fact sheet on hyperthermia at https://mothertobaby.org/fact-sheets/hyperthermia-pregnancy/ for more information about fevers.
Would having/getting a Staph infection cause other pregnancy complications?
If the amniotic fluid (fluid around the baby) were to become infected with Staph, this could cause preterm delivery (having the baby before 37 weeks). Babies can also get Staph infections from their moms at the time of birth. Most of the time this does not cause problems for the baby, but sometimes it can cause illness in the newborn.
Does having/getting a Staph infection in pregnancy cause long-term problems for the child?
It is not known if having a Staph infection during a pregnancy might cause long-term problems for the child.
Can I breastfeed while I have a Staph infection?
Staph infections are a common cause of mastitis infections in the breast. According to the American Academy of Pediatrics the milk is safe for the baby and individuals who have mastitis can continue to nurse.
It is possible that a Staph infection could spread to a nursing child during breastfeeding from direct skin contact. If you have a Staph skin infection, it is important to keep the wound covered with bandages so that the baby does not touch the wound or any discharge from it. This is important even if you are not currently breastfeeding. The baby could also become infected from contact with clothing, bedding or other materials that have the bacteria on them.
Additionally, there are some reports of infants getting a Staph infection through expressed (pumped) breast milk that was contaminated from pumping equipment or storage containers. Therefore, it is important to thoroughly wash and sterilize pumping equipment and storage containers, as well as your hands when pumping breast milk.
Not all Staph infections require treatment. However, if you are being treated, you can contact MotherToBaby to discuss your specific medication(s) during breastfeeding. Be sure to discuss your breastfeeding questions with your healthcare provider.
I have a Staph infection. Can it make it harder for me to get my partner pregnant or increase the chance of birth defects?
Some studies have suggested that a Staph infection might affect sperm and fertility. In general, exposures that fathers or sperm donors have are unlikely to increase the risk to a pregnancy.
