Kissing bugs and the hidden threat of Chagas disease
Kissing bugs in central and northern South America bite at night and can transmit the Trypanosoma cruzi parasite via their feces; this infection causes Chagas disease, which damages the heart and digestive muscles and can be fatal if untreated. The WHO estimates about 8 million people are infected worldwide with around 10,000 deaths annually, a history tied to Darwin’s South American travels.
