Chagas Disease endemic in Latin America arriving unknowingly with immigrants, costing millions

Chagas disease may be obscure, but the economic burden it imposes on the world is greater than that of better-known diseases, like cervical cancer or cholera, according to a new study. Even in the United States, the authors said, the costs of Chagas are commensurate with those of more publicized diseases, like Lyme disease. (In the same league, perhaps, but not quite equal. In their study, published in Lancet Infectious Diseases, the authors calculated that Chagas cost the American economy $900 million a year. A 1998 study estimated that Lyme disease cost $2.5 billion.) Chagas disease is caused by a trypanosome parasite transmitted by the bloodsucking “kissing bug,” which bites victims as they sleep. Transmission is endemic in much of Latin America, from central Mexico to northern Argentina. Kissing bugs have been found in the southern United States; the bugs tend to live in substandard housing and animal pens. Read Article
