Chagas disease in Mexico.

Mexico - the northernmost country of Latin America - has long been thought to have an unusually low prevalence of Chagas disease compared with other Latin American countries. This has seemed unusual because of the large number of vector species and subspecies reported from the country, and the social and ecological conditions that seem to parallel those in other countries where Chagas disease is recognized as a major public health priority. This review seeks to clarify the question, and suggests that the epidemiological, parasitological, and entomological pattern of Chagas disease in Mexico may also parallel that of other endemic regions, but has been masked by poor awareness of the disease both at local and institutional levels.
