After discovery of the first recorded case of human infection with , serologic screening of 1,806 persons from the village of origin of the patient in India was performed using the card agglutination test for trypanosomiasis and . A total of 410 (22.7%) people were positive by whole blood, but only 81 were confirmed positive by serum. However, no trypanosomes were detected in the blood of 60 people who were positive at a high serum dilution. The results probably indicate frequent exposure of the human population to in the study area, which suggests frequent vector transmission of parasites to humans. Although is not infective for humans, a follow-up of seropositive persons is required to observe the evolution of human infection with this parasite.
