Infections and Pregnancy

During pregnancy, some common infections like the common cold or a skin infection do not usually cause serious problems. But other infections can be dangerous to you, your baby, or both. Some infections may lead to preterm birth and low birth weight babies. Others can cause serious illness, birth defects, and lifelong disabilities, such as hearing loss or learning problems.

Some of the infections that can be dangerous during pregnancy include:

  • Bacterial vaginosis (BV)
  • Group B strep (GBS)
  • Hepatitis
  • Sexually transmitted diseases
  • Toxoplasmosis
  • Urinary tract infections
  • Yeast infections
  • Zika virus

To try to prevent infections,:

  • Don't eat raw or undercooked meat
  • Don't share food or drinks with other people
  • Wash your hands frequently
  • Don't empty cat litter. Cats can transmit toxoplasmosis.

If you do get an infection during pregnancy, contact your health care provider about how best to protect you and your baby. Only some medicines are safe during pregnancy.

Urinary Tract Infections

The urinary system is the body's drainage system for removing wastes and extra water. It includes two kidneys, two ureters, a bladder, and a urethra. Urinary tract infections (UTIs) are the second most common type of infection in the body.

You may have a UTI if you notice:

  • Pain or burning when you urinate
  • Fever, tiredness, or shakiness
  • An urge to urinate often
  • Pressure in your lower belly
  • Urine that smells bad or looks cloudy or reddish
  • Pain in your back or side below the ribs

People of any age or sex can get UTIs. But about four times as many women get UTIs as men. You're also at higher risk if you have diabetes, need a tube to drain your bladder, or have a spinal cord injury.

If you think you have a UTI it is important to see your doctor. Your doctor can tell if you have a UTI with a urine test. Treatment is with antibiotics.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
