Timely investigation is key to reducing the morbidity and mortality associated with events of non-seasonal influenza or other emerging respiratory disease pathogens. Investigations identify cases, and determine the cause of disease, the source and the most probable mode(s) of transmission, as well as the at-risk populations and exposures that may predispose individuals to infection.

The findings are then used to assess the risk posed by the event, and to develop and implement interventions that stop transmission. Strong linkages between human and animal health sectors are needed for investigations at the human–animal interface, and risk assessments are critical to guide control and prevention measures throughout the investigation and response process.
