ABSTRACT

Mexico is a territory with coastal plains stretching from sea level to an altitude of 900 meters and a torrid climate in which 100 million human beings live. There is an abundance of animal life that act as vectors for many different diseases such as malaria, dengue, leishmaniasis, oncocercosis and Chagas disease. The prevalence of Chagas disease in terms of morbidity is still important, although for some years the campaigns to control it have been constant and partially successful.
Each one of the mentioned diseases is described in detail, its changing epidemiology in the past few years, the parasites that cause the disease and their life cycle, the clinical manifestations that suggest their existence, the methods for reaching a definitive diagnosis, complications and finally treatment. In addition, prevention measures are discussed together with what is expected from a health point of view.
With exception of dengue, caused by a virus to which there are no useful pharmacological therapies for all of the rest we have reliable, active, low toxicity and reasonable medications throughout the country.
For nearly half a century there has been a level of optimism in the fight against the vectors to the point of believing in possible eradication of these diseases. However on the one hand, the insecticides have proven noxious to the biosphere and on the other, the parasites have become resistant. This has led to the new concept of compatibility of the vectorpathogen- host complex.
Presently the study of vector biology allows identification of biochemical molecular and genetic characteristic that will lead to a more effective prophylaxis, respectful of the ecosystem.
