American trypanosomiasis (aka. Chagas disease) is a tropical parasitic disease caused by the protist Trypanosoma cruzi. It is spread mostly by insects known as Triatominae, or "kissing bugs".
Will it affect animals or only human beings?
Yes, it also affects other mammals. Apart from humans, a number of mammals serve as reservoir hosts for T. cruzi. For example, armadillos, opossums, raccoons, woodrats, some other rodents, and domestic dogs.
What is American trypanosomiasis?
Generally speaking, it can either cause an acute condition or a chronic condition. In some cases, people don’t feel any symptoms until the chronic stage. If they do, symptoms may range from mild to severe,

1.    Acute phase
Symptoms are usually mild and may include: fever, headache, fatigue, rash, body aches, loss of appetite, nausea, diarrhea or vomiting, swelling at the infection site, swollen glands, eyelid swelling

2.    Chronic phase
Symptoms of this phase may occur 10 to 20 years after initial infection, or they may never occur. In severe cases, symptoms may include: irregular heartbeat, congestive heart failure, sudden cardiac arrest, difficulty swallowing due to enlarged esophagus, abdominal pain or constipation due to enlarged colon.
My husband was diagnosed with this disease 3 years ago and it seems to have entered a chronic phase. I’m so afraid that he may suffer from further complications. Is it possible that he will end up developing other diseases?
So sorry to hear that.. But it’s possible to develop other complications if it progresses to the chronic phase. For example, your husband may experience heart failure, enlargement of the colon and the esophagus, etc. But if treated well, your husband will be fine. For more info, you need to consult the Dr. and he may help lower the risk of your husband developing other diseases.
