Introduction. Influenza is an acute respiratory disease caused by influenza virus; these pathogens belonging to the Orthomixoviridae family and are classified into three genera or types: A, B and C, according to the immunological differences of the nucleoprotein. From the epidemiological point of view, the virus influenza A is the main cause of the epidemics in winter of influenza which are repeated every year (influenza epidemic), while the virus influenza B occurs almost always in more localized outbreaks and influenza C virus is associated with the appearance of sporadic cases. In clinic, usually, influenza is a self-limiting disease that affects the general population, and morbidity and mortality are particularly significant in certain so-called risk population groups; the condition is transmitted rapidly during seasonal epidemics and affects 10 to 20% of the population.1 the typical clinical manifestations of influenza are fever, myalgia, sore throat, rhinitis and headache. The most people who get influenza will be restored to one or two weeks. In some individuals, most of the time over the age of 65 years, children very small and subjects with chronic health problems, disease can complicate or lead to pneumonia, or both.

Influenza viruses that occur each year during the winter are often linked with an increase in hospitalization and mortality rates. The last few weeks the media we have been bombarded with note after note about human influenza and media have inflated information, both that we have blinded in the other news affecting our country. Flu infected more than 942 persons in our country of whom died only only the estimated 29 people, however millions of Mexicans were left uninformed of what happened this week in which Mexico stood and the average population stay in extreme ignorance thanks to the huge coverage that I take has the disease. Personally I question as many analysts, taking a skeptical stance of the matter, however the media led to social chaos, which is cayo tourism and Mexican economic production.
