Several vector-driven diseases such as malaria and leishmaniasis are endemic in the Amazon region; however, socio-environmental changes are altering their natural dynamics . An important relationship between the outbreak of infectious diseases and changes in climatic events  or environmental events  has been found to exist for the Brazilian Amazon  . These impacts are more severe in poor populations with limited access to health services . In the case of Venezuela, the impact of climate change on the epidemiology of malaria has been studied, showing significant influence on transmission in the Amazonia area of the country  . Other studies from Venezuela have documented the role of ENSO in dengue outbreaks . Table 12.1 shows the changes observed in reproduction potential for dengue in the different sub- regions due to changes in rainfall and temperature. Forest fires pose a major threat to public health in the region because they relate to an increase in hospital admissions due to respiratory problems, mainly among children and the elderly . The amount of air pollutants detected is sometimes higher than that observed in large urban areas, especially during dry seasons when biomass burning increases .
