Rhodnius prolixus

Rhodnius prolixus

Rhodnius prolixus is a triatomine vector of the Chagas disease parasite, Trypanosoma cruzi, in South and Central America. Chagas disease is a chronic condition which affects 8 to 10 million people and is the cause of around 20,000 deaths per year.

Triatomine insects release parasites in their faeces immediately after a blood meal. Infection occurs after the human host scratches the bite area, thus transferring parasites into the bite wound.
