abstract = "A temporal series of the normalized difference vegetation index
(NDVI) and other environmental parameters covering the years 2002-
2009 was used for the study of the potential association between
the climate and the number of cases of American cutaneous
leishmaniasis (CL) in Manaus Metropolitan Region (MMR), State of
Amazonas, Brazil. The results show that CL has a marked
seasonality and a strong linkage with local climate conditions.
Dry and warm conditions favor the vector, while the maximum number
of CL cases occurs during the following wet season. This has a
clear relation to the El Niņo/La Niņa Southern Oscillation (ENSO)
and the results presented here show that uncharacteristic dry
conditions in the MMR follow El Niņo after a lag period of 3
months, while wet conditions follow La Niņa, again after a lag
period of 3 months. El Niņo brings dry conditions with warming of
the land surface leading to increased growth of trees and bushes
as indicated by rising NDVI values, eventually producing increased
numbers of CL cases, with a peak of new cases occurring 4 to 5
months later. La Niņa, on the other hand, produces wet and cool
weather, which is less favorable for the leishmaniasis vector and
therefore results in comparatively lower number of CL cases. Since
these seasonal climate changes affect the dynamics of the CL
vector, and thus the number of CL cases, a close watch of the ENSO
phenomenon and the weather type it brings should be useful for
monitoring and control of CL in the MMR.",
