Certain infections during pregnancy may lead to or cause complications or health problems for your fetus, such as:
- Preterm birth
- Low birth weight
- Serious illness
- Birth defects
- Lifelong disabilities, such as hearing loss or learning problems

What are the symptoms of an infection during pregnancy?
Sometimes, it's hard to know what's normal during pregnancy. Symptoms of an infection can vary based on the infection. Talk with your health care provider about what symptoms to look for and how to keep healthy. But, if something is worrying you, share your symptoms with your provider for early detection and treatment of infections.
What are the treatments for infections during pregnancy?
If you do get an infection during pregnancy, contact your provider about treatment that will best protect you and your fetus. Only some medicines are safe during pregnancy.
Can infections during pregnancy be prevented?
Taking care of yourself and getting early and regular prenatal care from your provider may help identify and treat infections early.
