Multiple Choice

Which transmission route is associated with Chagas disease?

Chagas disease is transmitted mainly through fecal contamination from the insect that has bitten you. Infected triatomine bugs defecate during or after feeding, releasing the parasite in their feces. When those feces contact the bite wound or your mucous membranes—such as your eyes, mouth, or any scratched area—the parasites can enter your body and establish infection. This makes fecal contamination the best description of the transmission route. Other ideas like the bite itself injecting the parasite or the idea of regurgitation aren’t the primary routes the parasite uses. The key point is that the infectious material is in the bug’s feces, not in the bite itself.
