Les Européens ont-ils apporté la lèpre en Amérique ?
Contrairement à ce qu’on pensait, la lèpre existait déjà en Amérique depuis plus de mille ans, véhiculée par une autre bactérie. Ce qui n’a pas empêché les colons de l’apporter aussi.

Un azote antiguo: la lepra circulaba en América antes de la llegada de los europeos
En colaboración con comunidades indígenas, un equipo internacional de 40 científicos halló ADN de una de las dos bacterias responsables de esta enfermedad estigmatizante en los restos de individuos que vivieron en lo que hoy es Argentina y Canadá hace más de mil años.
