Chagas Disease

What is Chagas disease?

Chagas disease, or American trypanosomiasis, is an illness that can cause serious heart and stomach problems. It is caused by a parasite. Chagas disease is common in Latin America, especially in poor, rural areas. It can also be found in the United States, most often in people who were infected before they moved to the U.S.

What causes Chagas disease?

Chagas disease is caused by the Trypanosoma cruzi parasite. It is usually spread by infected blood-sucking bugs called triatomine bugs. They are also known as "kissing bugs" because they often bite people's faces. When of these bugs bites you, it leaves behind infected waste. You can become infected if you rub the waste in your eyes or nose, the bite wound, or a cut.

Chagas disease can also spread through contaminated food, a blood transfusion, a donated organ, or from mother to baby during pregnancy.

Who is at risk for Chagas disease?

Kissing bugs can be found throughout the Americas, but they are more common in certain areas. The people who are most at risk for Chagas disease:

How is Chagas disease diagnosed?

Can Chagas disease be prevented?

There are no vaccines or medicines to prevent Chagas disease. If you travel to areas where it occurs, you are at higher risk if you sleep outdoors or are staying in poor housing conditions. It is important to use insecticides to prevent bites and practice food safety.
