Influenza is a highly contagious acute viral infection of the respiratory tract. It is caused by influenza A, B and C virus. Infection occurs at all ages, but during epidemics the morbidity is higher at extremes of life. Sick patients demand medical care and hospitalization, consuming limited resources, increasing length of hospital-days and eventually death. Recently, in Mexico a novel influenza A virus (H1N1) caused an epidemic. With the new virus surveillance, infections due also to seasonal virus were documented. This update highlights recommendations for prevention and treatment of influenza.
