Answer

The prevalence of T gondii antibodies in US military recruits decreased by one third from 1965-1989; the crude seropositivity rate among recruits from 49 states was 9.5% in 1989, compared with 14.4% in 1965. T gondii infection affects more than 3500 newborns in the United States each year. T gondii seropositivity rates among patients with HIV infection vary from 10-45%.

Toxoplasmosis are more common in southern states, in African Americans, and in populations with lower socioeconomic status. [28]
