Operational Guidelines for Sentinel Severe Acute Respiratory Infection (SARI) Surveillance; 2014

The influenza A(H1N1) pandemic of 2009 highlighted the importance of collecting information about disease severity in a standardized manner and having historical data available for countries to assess current influenza seasons in the context of previous ones. To address these objectives and help promote comparability of surveillance data between countries in the Region of the Americas, PAHO developed the Operational Guidelines for Intensified National SARI Surveillance in January 2011.
