The dogs that had been submitted the treatment must pass for clinical and laboratorial evaluation to each six months, for control of illness of base and monitoramento of the functions and the agencies supposedly reached. Control of the Leishmaniose leishmaniose is a infectum-contagious illness that stops its propagation demands the competition of a vector – the flebotomdeo – and of at least a host, either it animal Sylvester, domestic animal, amongst them the dog, or even though the man. For these reasons, one program that pursues a true effectiveness must prioritize the combat to the insect-straw. Without the elimination of the mosquito it does not have the combat of the illness. This is obvious! The combat to the mosquito is of great complexity, as much in urban areas, how much in forests, for requiring man power, investment, sanitary education and will politics, over all. In urban areas the complexity level seems diminished, since it is possible to mapear the focos and to remove the conditions of reproduction and survival to them.
It has cases, also, that frank reduction of the insect-straw was evidenced together with combat to the Aedes aegypti, transmitting mosquito of the affection. When the focus is in areas of forest little can be fact, given the impossibility of if manipulating with the wild sources of contamination. Narrow relation exists enters the modification of the natural environment of the flebotomneo (deforestations, forest fires, etc.) and its consequent sprouting in urban areas. This is the main one, perhaps until the only condicionante factor of the migration of the insect-straw, has seen its habitat natural to be the forest. On Brazil the programs of control of leishmaniose are based basically on the extermnio of dogs. In some places, presented until as alternative only. The sacrifice of dogs does not diminish the incidence of the illness, because the dog is an accidental host, as well as the man also is.
