Worldwide, the incidence of congenital infection ranges from 1–7/1,000 live births; in the US, incidence is estimated at 0.1–1/1,000 live births. It is believed that 400–4,000 infants are born annually in the US with congenital toxoplasmosis.
Seroprevalence rates among pregnant women vary from 4–80% worldwide; in the US, a serologic survey found 15% of women of child-bearing age were seropositive.

The term 'prevalence' of Toxoplasmosis usually refers to the estimated population of people who are managing Toxoplasmosis at any given time. The term 'incidence' of Toxoplasmosis refers to the annual diagnosis rate, or the number of new cases of Toxoplasmosis diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
