Molecular Characterization of Trypanosoma cruzi Reactivation and Follow-up in a Case Series of People With HIV.

We characterize Trypanosoma cruzi infections from blood and cerebrospinal fluid samples in a case series of people with human immunodeficiency virus and Chagas disease. We identify different infecting T. cruzi populations, highlighting the usefulness of real-time polymerase chain reaction for Chagas disease reactivation diagnosis and evaluation of treatment response.
