The virulence and antigenicity of the virus, host immunity and environment, interact with each other affecting the transmission of the virus person-person. Since the alert in 2009 of the influenza due to the H1N1 virus, the number of new cases increased despite the control measures implement, such as wearing masks, and other recommendations made by the World Health Organization. In Colombia it was found that the first case of AH1N1 coincided with a person from Mexico. Therefore, and considering that all travelers from this country are a suspected case of the disease, it makes the transit from one country to another a possible route of transmission. Hence, the approach to the question: What has been the impact in Colombia of the outbreak caused by the migration of people from Mexico infected with the H1N1 influenza virus? The porpuse of this paper is, in ...

In the model we define a function depending on age which is used to determine the contact rate of infections individuals with groups dierentiated by age. The
