The Kiss of Death

Chagas’ disease has become one of the major public-health problems in Latin America. Current estimates are that sixteen to eighteen million people are infected. Caused by a flagellate protozoa carried to humans via the bite of the or bug, it is locally referred to as the “kissing bug” because of its tendency to lodge on victims’ faces during sleep. The protozoa enters neuron tissues in the heart and other organs and causes death by irreversible cardiac and gastrointestinal lesions in thirty to forty percent of all cases, usually lying “dormant” until the debilitating chronic phase during the human host’s mid-life. Because of the long dormant phase, it has generally gone unrecognized, with chronic symptoms often attributed to other causes. Originally preying on forest animals, the bug has infested the impoverished housing of displaced Andean migrants as forest lands and animals have been destroyed in South America. Although there is no cure for the chronic stage, the disease vectors can be controlled and possibly eliminated through improved hygiene and living conditions. No longer exclusive to Latin America, Chagas’ disease is spreading to North America and Europe with the migration of infected bugs, hosts, transfusions, and transplant organs.
