Answer

Congenital toxoplasmosis is usually a subclinical infection. Among immunodeficient individuals, toxoplasmosis most often occurs in those with defects of T-cell–mediated immunity, such as those with hematologic malignancies, bone marrow and solid organ transplants, or acquired immunodeficiency syndrome (AIDS).In most immunocompetent individuals, primary or chronic (latent) T gondii infection is asymptomatic. A small percentage of these patients eventually develop retinochoroiditis, lymphadenitis, or, rarely, myocarditis and polymyositis. (SeePresentation and Workup.)
