Influenza affects 10 to 20% of the world population, it causes 3 to 5 million cases and 250 thousand to 500,000 deaths per year. In Panama, 40% of acute respiratory infections are caused by viruses, the third place corresponds to influenza. This is a cross-sectional descriptive study that seeks to evaluate the efficiency, effectiveness and timeliness of the information system (SISVIG & SIES) in Veraguas. SISVIG and SIES databases of Veraguas were analyzed, during 2017, in this same year SISVIG 2797 and SIES 3263 were notified of influenza cases, for a rate of 9.8 and 13.4 per 1000 people respectively. In both systems, these cases predominated in the rainy season (June-October), children under 5 years and adults over 50 years are the most affected groups, and the influence rates are higher in women than in men. There are important differences between the two systems using the same source of information.
