Chagas disease is caused by a parasite. It is common in Latin America but not in the United States. Infected blood-sucking bugs, sometimes called kissing bugs, spread it. When the bug bites you, usually on your face, it leaves behind infected waste. You can get the infection if you rub it in your eyes or nose, the bite wound or a cut. The disease can also spread through contaminated food, a blood transfusion, a donated organ or from mother to baby during pregnancy.
If you notice symptoms, they might include
These early symptoms usually go away. However, if you don't treat the infection, it stays in your body. Later, it can cause serious intestinal and heart problems.
A physical exam and blood tests can diagnose it. You may also need tests to see whether the disease has affected your intestines and heart.
Medicines can kill the parasite, especially early on. You can also treat related problems. For example, a pacemaker helps with certain heart complications.
