If you have a normal immune system, you're not likely to experience any complications of toxoplasmosis, although otherwise healthy people sometimes develop eye infections.

But if your immune system is compromised, especially as a result of HIV/AIDS, toxoplasmosis can lead to seizures and life-threatening illnesses such as encephalitis — a serious brain infection. In people living with AIDS, untreated encephalitis resulting from toxoplasmosis is fatal. Relapse is a constant concern for immunocompromised people with toxoplasmosis.

Children with congenital toxoplasmosis may develop disabling complications, including hearing loss, mental disability and blindness.
