The "kissing bug" is a common name for insects in the Triatominae subfamily, known for their tendency to bite humans around the mouth and eyes while they sleep. These bugs are primarily found in the Americas, especially in rural areas of Latin America. They are nocturnal and are attracted to warmth and carbon dioxide emitted by sleeping individuals. Kissing bugs can carry the Trypanosoma cruzi parasite, which causes Chagas disease. This disease can lead to serious health issues if left untreated, including heart problems and digestive disorders. Preventive measures include improving housing conditions and using insecticides to control their populations.
