How common is toxoplasmosis in pregnancy?
We don't know exactly how many pregnant women get toxoplasmosis. Rates of infection vary from country to country and from time to time.

What we do know that toxoplasmosis in pregnancy isn't common.

In the United States, about 2 in 1,000 to 6 in 1,000 pregnant women get toxoplasmosis.1

Researchers think that about 85 in 100 of women of childbearing age are at risk of getting toxoplasmosis because they haven't had it before.2 But once you've had the infection you are immune for life.

Nobody knows exactly how many babies are born with congenital toxoplasmosis (babies who became infected in the womb). But in the United States, researchers think it's about 400 to 4,000 babies each year.3
