Monitor infants of mothers with T cruzi infection. Infants who are parasite-negative at birth should be tested serologically at ages 6 and 9 months, after maternal antibodies have disappeared. Treatment should be instituted when results are positive.

Persons with T cruzi infection should undergo electrocardiography every 6-12 months to look for dysrhythmias (see Other Tests).

Patients with clinically manifest cardiac or gastrointestinal Chagas disease should be managed by appropriate specialists (see Consultations).

Weekly white blood cell counts should be performed in patients being treated with benznidazole to evaluate for agranulocytosis.

Immunosuppressed persons with T cruzi infection who have unexplained febrile illnesses should be evaluated parasitologically for reactivation of the infection.
