Detailed explanation-1: -The cause of Chagas disease is the parasite Trypanosoma cruzi, which is spread from an insect known as the triatomine bug, or “kissing bug.” These insects can become infected by this parasite when they swallow blood from an animal that is infected with the parasite.

Detailed explanation-2: -Chagas disease, or American trypanosomiasis, is caused by the parasite Trypanosoma cruzi. Infection is most commonly spread through contact with the poop of an infected triatomine bug (or “kissing bug”), a blood-sucking insect that feeds on humans and animals.

Detailed explanation-3: -People who have Chagas disease can be found anywhere in the world. However, transmission of the disease by kissing bugs (vectorborne transmission), only occurs in the Americas. Most people with Chagas disease became infected in rural areas of Mexico, Central America, and South America.

Detailed explanation-4: -Triatomine bugs are a type of reduviid bug that can carry Trypanosoma cruzi, the parasite that causes Chagas disease.

Detailed explanation-5: -If kissing bug feces enters someone’s body, the parasite can infect the person and cause Chagas disease. Some kinds of kissing bugs poop while they are feeding; if a person scratches the kissing bug feces into the bite then the person may get sick.
