Chagas disease is most commonly spread through?

Explanation:
Chagas disease is transmitted mainly through the bite of triatomine bugs (kissing bugs), but the key event is not the bite itself. The parasite Trypanosoma cruzi lives in the bug’s feces, and when the bug feeds, it defecates near the bite. The parasite enters the body when a person inadvertently rubs these feces into the bite wound or mucous membranes. This fecal transmission is the typical, most common route. The other options don’t fit this disease: Anopheles mosquito bites spread malaria, contaminated water can carry different pathogens like Giardia, and airborne droplets transmit respiratory infections.
