Is Chagas disease sleeping sickness?

Chagas disease and sleeping sickness are both infectious diseases caused by the parasite Trypanosoma. In particular, Chagas disease is caused by the parasite Trypanosoma cruzi, while sleeping disease is caused by Trypanosoma gambiense. These parasites live in animals and can be transmitted from person to person.

What is the incubation period for Chagas disease?

After the incubation period of 1 to 2 weeks, infected patients enter the acute phase of Chagas disease. Transfusion- and transplant-associated cases may have a longer incubation period, sometimes up to 120 days.

What does kissing bug poop look like?

Feces may be spread on walls and can be both white and dark, and usually look like stripes. Eggs can be found in wall crevices and are mostly white or pinkish.
