π§ββοΈ Chagas disease was first described in 1909 by Carlos Chagas in Brazil. It is caused by the protozoan Trypanosoma cruzi, transmitted by the faeces of the triatomine (reduviid) bug.
ποΈ Triatomine bugs thrive in cracks of poorly built houses (mud, thatch, adobe). π They feed at night β people in endemic areas should avoid sleeping in such dwellings or outdoors.
π‘ Exam tip: Think Chagas if you see Romanaβs sign (eyelid swelling) in acute disease, or unexplained dilated cardiomyopathy in a South American patient.
