Kissing bugs cause heart damage in millions

Chagas disease, caused by the microscopic parasite Trypanosoma cruzi, silently destroys heart muscles in millions worldwide. Transmitted by "kissing bugs," the parasite enters the body through skin abrasions or mucous membranes. While early symptoms are often mild, the chronic phase, affecting 20-30% of cases, triggers inflammation that devastates cardiac cells, leading to heart failure years or even decades later. This makes Chagas a leading cause of heart disease in Latin America, contributing to 10,000-12,000 deaths annually. The parasite's ability to hide from the immune system highlights why early diagnosis is crucial, even as it spreads globally through blood transfusions and congenital transmission.
