Chagas Biovigilance Network

The Chagas Disease Biovigilance Network records screening and confirmatory results from the testing of donors for antibodies to Trypanosoma cruzi, the agent of Chagas disease. Current data are being provided by those laboratories that are using tests licensed by FDA to screen blood donors for the T. cruzi antibody. As of April 30, 2010, the FDA has approved two blood donor screening tests to screen blood, tissue, and organ donors for the blood-borne parasite T. cruzi. These laboratories account for more than 65 percent of the total blood collected in the U.S.


Resources for blood collection sites investigating suspected autochthonous T. cruzi cases are available through the Centers for Disease Control and Control, Parasitic Diseases at +1.404.718.4745 or


This section includes maps showing the latest confirmed positive cases by ZIP code and a password-protected area for reporting of test results as well as more in-depth monitoring and assessment of Chagas activity. Each pinpoint  shown on this map represents the center of the residential postal code of the donor from which the test result for the test for antibodies to Trypanosoma cruzi was reported, and not the specific address or location of any individual or facility. Maps are updated twice daily (approximately every 12 hours).
