AABB 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 the test licensed by FDA in January 2007 to screen blood donors for the T. cruzi antibody. These laboratories account for more than 65 percent of the total blood collected in the U.S.
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.
Maps are updated weekly. For the most currently reported data, please use the reports, which access the active Chagas' Biovigilance Network database.
