Answer

The seroprevalence of T gondii antibodies in the human population varies geographically, with prevalence rates approaching 90% in some European countries, while seropositivity rates in the United States have been estimated to fall between 10% and 15%. [4, 5] Infection with the human immunodeficiency virus (HIV) does not seem to effect T gondii seropositivity, and there does not appear to be any difference in the rate of toxoplasmosis infection among patients with AIDS with and without cats.
