Toxoplasmosis: Toxoplasmosis - epidemiology
(The 5-Minute Pediatric Consult)

  • The rate of acquired infection, usually asymptomatic, varies widely through the world and increases with age.
  • 70–90% of children with congenital toxoplasmosis are asymptomatic at birth. Late sequelae (e.g., chorioretinitis, mental retardation, seizures, sensorineural hearing loss) occur in >50% of untreated infants considered asymptomatic at birth.

Toxoplasmosis - incidence

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.

Toxoplasmosis - prevalence

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.

About prevalence and incidence statistics:

The term 'prevalence' of Congenital Toxoplasmosis usually refers to the estimated population of people who are managing Congenital Toxoplasmosis at any given time. The term 'incidence' of Congenital Toxoplasmosis refers to the annual diagnosis rate, or the number of new cases of Congenital 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.
