[Background]. Since the 2009 influenza pandemic, countries of the Americas have been strengthening their surveillance systems to improve detection of novel influenza subtypes and monitoring of seasonal influenza epidemics. These systems, when functioning optimally, allow public health decision makers to understand when, where, and who is being affected by influenza during seasonal epidemics and should detect the emergence of a novel influenza subtype in a timely manner. The first surveillance systems to be developed in most countries in the Region were laboratory-based surveillance systems, which would allow the detection of a novel influenza subtype if a clinical sample were collected and tested in the laboratory. Since this time, many other systems have been developed to complement and integrate with the laboratory surveillance platforms, which allow for monitoring of influenza, pneumonia, and clinical influenza proxy syndromes in the ambulatory and hospitalized settings (e.g. influenza-like illness [ILI] and severe acute respiratory infection [SARI]). There are systems which are both indicator-based as well as systems which rely upon event-based information (e.g., tracking of media reports).The result of these efforts is that now, there are a variety of systems that contribute to the understanding nationally, regionally, and globally, of influenza. This publication represents a compilation of the respiratory virus surveillance systems that exist in countries throughout the Americas Region and is an update to the 2014-publication, “Influenza and Other Respiratory Virus Surveillance Systems in the Americas, 2014”. he 2016-2017 inventory includes two sections: Regional Analyses and Country-by-country Analyses. The regional section includes regional data, maps showing capacities that exist in the region, and frequency of data reporting to FluID and FluNet...
