Abstract
Until recently, the main objectives of influenza surveillance both worldwide and in the Region of the Americas have been the early detection of a new influenza virus strains and the ongoing analysis of viral circulation patterns at both the regional and national levels. The need to expand influenza surveillance to include other objectives has become evident in recent years. To this end, a new Generic Protocol for Influenza Surveillance (GPIS) was developed in collaboration with the U.S. Centers for Disease Control and Prevention (CDC). The GPIS seeks to harmonize influenza surveillance throughout the Region and ensure that any single case of influenza caused by a new viral subtype be detected, as required by the revised International Health Regulations (IHR 2005). Furthermore, generation of robust data of the epidemiological characteristics of influenza will provide a better understanding of viral circulation patterns in tropical areas to guide decision-making regarding the introduction of vaccine.
