Chagas disease posts lifelong threat of heart failure

Chagas disease is transmitted by the kissing bug, which carries the Trypanosoma cruzi parasite. Predominantly found in Central and South America, it affects up to 11 million people. The disease has an acute phase with symptoms like fever and swelling, which can be cured in 90% of cases if treated early. If untreated, it progresses to a chronic phase, potentially causing heart and digestive system damage, leading to heart failure and death. Cure rates decrease over time.
