5 Must Know Facts For Your Next Test
Triatomine bugs are vectors for Trypanosoma cruzi, causing Chagas disease.
They are commonly called 'kissing bugs' due to their tendency to bite near the mouth or eyes of sleeping humans.
Transmission primarily occurs through contaminated feces of the bug entering bite wounds or mucous membranes.
Acute Chagas disease can present with fever, fatigue, body aches, and swelling at the infection site.
Chronic Chagas disease can lead to serious heart and digestive system complications.
