Patrones y tendencias de la lepra en México: 1989-2009 / No disponible

Se analizan los datos obtenidos del Programa Nacional de Control de Lepra (PNCL) de México entre 1989-2009. Después de un incremento inicial asociado a la introducción de la multiterapia MDT y el comienzo de la iniciativa global de eliminación a principios de los años 90, tanto prevalencia como incidencia disminuyeron dramáticamente en todo el país. En 1994 la prevalencia disminuyó a menos de 1 por 10.000 y así ha permanecido hasta la actualidad. Hay una gran variedad geográfica, con la mayor detección en la parte oeste del país bordeando la zona del pacífico y la menor en el sureste. Las causas de esta heterogeneidad no son evidentes. Existen evidencias de incremento de edad en los casos detectados, mayor proporción de casos MB y en varones, como en otros muchas poblaciones y países con disminución de la incidencia. Hay un ligero aumento de los casos en la zona fronteriza con Texas, Estados Unidos, donde habitan armadillos. La importancia de los armadillos en la incidencia de la lepra en México no está muy claro, pero exige prioridad en su investigación (AU)

Data from the Mexican national leprosy control programme 1989-2009 are described and analysed. After initial increases associated with the introduction of MDT and the start of the global elimination initiative in the early 1990s, both prevalence and incidence declined dramatically throughout most of the country. Reported prevalence fell below 1 per 10 000 in 1994 and has remained below that level ever since. There is considerable geographic heterogeneity, with highest case detection rates in western states bordering the Pacific and lowest in the south east. Reasons for these geographic differences are unclear. There is evidence of increases in average age of cases, and in proportions male and MB, as in several other populations with declining leprosy. There is some evidence of increasing leprosy in states bordering on Texas, USA, where M. leprae is known to be harboured in armadillos. The relevance of armadillos for leprosy in Mexico is unclear but a priority question (AU)
