  • Risk Factors for Infections in Pregnancy

    A risk factor is something that increases your likelihood of getting a disease or condition.
    It is possible to get an infection in pregnancy even if you do not have risk factors.
    Risk factors for infection in pregnancy vary depending on the type of infection. General risk factors for infection during pregnancy include:
    Viruses and bacteria that cause infections are passed through person-to-person contact. You are at higher risk of spreading and getting infections caused by bacteria and viruses if you:
    • Do not wash your hands.
    • Touch your nose, mouth, and eyes with contaminated fingers.
    Sexually transmitted diseases (STDs) such as chlamydia , gonorrhea , herpes simplex virus, and HIV are passed from person to person during sexual contact. Your risk for STDs is higher if you have had:
    • Many sex partners
    • Sex with someone who has had many partners
    • Sex without using condoms
    Germs that cause infections such as listeriosis and toxoplasmosis have been found in:
    • Uncooked meats
    • Undercooked meat (such as rare beef) from infected animals
    • Uncooked vegetables
    • Unpasteurized milk
    • Foods made from unpasteurized milk (eg, certain cheeses)
    • Processed foods
    Your risk for these infections is higher if you eat these foods.
    Lifestyle risk factors include:
    • Having close contact with someone who has an infection
    • Using household items that were used by an infected person and not properly cleaned
    • Handling cat litter or soil where there is cat feces
    • Having a job that involves contact with bodily fluids, such as a:
      • Childcare worker
      • First aid or emergency worker
      • Funeral director
      • Healthcare worker
      • Dentist
      • Dental assistant
      • Firefighter
      • Police personnel
