Anyone can become infected with toxoplasmosis. The parasite is found throughout the world.

You're at risk of serious health problems if:

  • You have HIV/AIDS. Many people with HIV/AIDS also have toxoplasmosis. In some cases, the infection is recent, and in others, an old infection has become active again.
  • You're undergoing chemotherapy. Chemotherapy affects your immune system, making it difficult for your body to fight even minor infections.
  • You take steroids or other immunosuppressant drugs. Medications used to treat certain nonmalignant conditions suppress your immune system and make you more likely to develop complications of toxoplasmosis.
  • You're pregnant. If you have active toxoplasmosis, treatment can reduce the risk to your baby. If you've already had toxoplasmosis before becoming pregnant, you generally can't pass the infection to your baby.
