The zoonotic diseases represent a constant risk for humans and animals; the epidemiology behaviour of this kind of agents that produce fatal epidemics in the whole world have been studied for years, it is important to maintain updated information that directs people about the diseases behaviour, so that they can act properly during the presentations of a zoonotic event. In Colombia a piece of work was carried out which reflects the behaviour of some zoonosis until 1997, from this date on, independent studies have been developed which notify the behaviour of some diseases, specially those that have represented an important risk for public health. Most of the facts about zoonotic cases in Colombia are compiled with this work from 1997 to 2003, where a retrospective epidemiology analysis is carried out to know the behaviour of these agents during the last years and try to predict for each one of them. There is a control over the viral diseases thanks to the vaccination programs, and the daily report from the clinics. The parasites and the fungus are opportunist invading that have been developed in a big scale, since they find a suitable environment similar to the sanitary costumes in human beings, besides they are helped by the primary agents that benefice the habitats. In the country it is important to know deeply about this kind of diseases, because they have become permanent hosts in this environment, and the clinic expression of zoonosis is the weapon to fight against these situations that involve the whole society.

The zoonotic diseases, represents a constant risk for humans and animals, during years it had been studied the epidemiology behaviour of this kind of agents that produce fatal epidemics in the whole world, is important to maintain current information that direct people about the behaviour of diseases to let them act properly during the presentations of a zoonotic event. In Colombia was made a work that reflects the behaviour of some zoonosis until 1997, from this date it has been development independent studies that notify the conduct of some diseases, over all those that had represent an important risk for public health. Whit this work are compile the most number of facts about zoonotic cases in Colombia since 1997 to 2003, where is done a retrospective epidemiology analysis to know the behaviour of this agents during the last years and try to predict for each one of them. In general there is control over the viral diseases thanks to the vaccination programs, the Colombian geography, is an environment colonize by bacteria, that depends on men and animals and they health level, whit this attitude keep a regularity that is reflected in the journals of the health centres. The parasites and fungus are opportunist invading that had been development in a big screen, because they are in a suitable environment according to the sanitary costumes of human been, besides they are help by the primary agents that benefice the habitats. In the country is important that population know about this kind of diseases in a deeper way, because they are permanents hosts in this ambient and the clinic expression of zoonosis are the weapon to fight against situation that involves the whole society.
