Chagas disease
• Protozoan parasite Trypanosoma cruzi only found in the Americas
• Vector-borne zoonosis, many animal reservoirs
• Transmission– Triatomine bugs – most common – Congenital– Contaminated blood components, organ or tissue– Laboratory accidents– Foodborne
• Estimated 8 – 11 million people have Chagas disease in Latin America
![Page 7: August 2009 CDC Selected Zoonotic Diseases Conference Call](https://reader033.fdocuments.us/reader033/viewer/2022052906/558c77ccd8b42a566c8b465a/html5/thumbnails/7.jpg)

Clinical diagnosis of Chagas disease
• Acute phase– Detection of circulating parasite– PCR– Problems with sensitivity
• Chronic phase– Persistent circulating antibody– Problems with specificity and sensitivity
• No gold standard test for Chagas disease
![Page 9: August 2009 CDC Selected Zoonotic Diseases Conference Call](https://reader033.fdocuments.us/reader033/viewer/2022052906/558c77ccd8b42a566c8b465a/html5/thumbnails/9.jpg)
Clinical Chagas disease
• Acute phase ~4 – 8 weeks, usually asymptomatic
• Chronic phase lifelong– Asymptomatic indeterminate form– 10 – 30% develop symptomatic disease
• Cardiac – sudden death, stroke• Gastrointestinal
• Treatment drugs difficult to tolerate and most effective during early infection
![Page 10: August 2009 CDC Selected Zoonotic Diseases Conference Call](https://reader033.fdocuments.us/reader033/viewer/2022052906/558c77ccd8b42a566c8b465a/html5/thumbnails/10.jpg)
Who is at risk in the U.S.
• People who acquired the infection in endemic countries of Latin America– Travelers to endemic areas
• People who acquire the infection in the United States– Exposed to infected vectors/ reservoirs – Children of infected mothers– Transplant recipients– Transfusion recipients– Laboratory staff working with vectors, reservoir
species, or parasite

Chagas disease in the United States
• Based on immigrant population data in the U.S., there are an estimated*– 300,167 people chronically infected – 30,000–45,000 cardiomyopathy cases– 63–315 congenital infections annually
• Not nationally notifiable disease– Reportable only in AZ and MA

FDA approves first blood donation screening assay December 2006
• Screening for antibody to T. cruzi • Most blood centers started screening
early 2007• ~75 – 90 % of the blood supply
currently screened• March 2009 FDA issues draft guidance
– Deferral of donors based on screening test– Universal screening, likely will revise to less
frequent screening– Lookback of previous donations by positive
donors– Can use radioimmune precipitation assay (RIPA)
to confirm

Are healthcare providers aware of Chagas disease?
• Most are not– ACOG Knowledge/ Attitude/ Practices
(KAP) surveys– Medscape KAP surveys of subspecialties
• Updated recommendations for treatment BUT many still refer to older practices
• Many donors seeking care from primary healthcare providers, clinics for the uninsured
![Page 16: August 2009 CDC Selected Zoonotic Diseases Conference Call](https://reader033.fdocuments.us/reader033/viewer/2022052906/558c77ccd8b42a566c8b465a/html5/thumbnails/16.jpg)
Treatment drug availability in United States
• Nifurtimox and benznidazole only antiparasitic medicines used to treat Chagas disease (in United States)
• Not FDA approved • Available only from CDC under
investigational protocols• Of 940 identified positive blood donors,
only approx. 11% have contacted CDC for treatment
