Risk Factors for Infections in Pregnancy

A risk factor is something that raises your chances of having a health problem. You can get an infection even if you do not have risks. The risks are not the same for each infection. The basic ones are:
Viruses and bacteria that cause infections are passed through contact with infected people. You are at higher risk if you:
  • Do not wash your hands.
  • Touch your nose, mouth, and eyes with contaminated fingers.
Sexually transmitted infections (STIs) are passed from person to person during sex. Your risk 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 have been found in:
  • Uncooked meats
  • Undercooked meat , such as rare beef, from infected animals
  • Uncooked vegetables
  • Unpasteurized milk
  • Foods made from unpasteurized milk
  • Processed foods
Your risk is higher if you eat these foods.
Lifestyle factors are:
  • Having close contact with someone who has an infection
  • Using household items that were used by an infected person and not 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 staff
