American mucocutaneous leishmaniasis is an important health problem in
Peru, particularly in the mountainous Cuzco Region, where 25% of all
new cases reported in 1989 were located. Cases have increased consider
ably since the beginning of the 1980s, when large-scale seasonal migra
tion to endemic zones occurred, particularly the forest area of Madre
de Dios, following the discovery of new gold deposits there, and the d
eterioration in the economic situation in Peru. Following the lack of
official response from the Peruvian government, hundreds of people suf
fering from leishmaniasis in the Cuzco area formed self-help associati
ons with the objective of obtaining the drugs needed to treat their di
sease. The major achievement of this spontaneous movement, which was s
upported by several public and private institutions, was to encourage
sick people, particularly patients with mucosal lesions, to emerge fro
m isolation. As a result, the prevalence and incidence of the disease
have now considerably decreased in the region.
