Health Protection Scotland (HPS), a division of NHS National Services Scotland (NSS), has produced this report to inform its parent board about the national coordination of the health protection response to the pandemic on influenza A(H1N1) infection in 2009/10. It is also to act as a reference for the management of any further like events.In accord with guidance from the Scottish Government (SG, 2003) after a major outbreak affecting its local population each NHS board should review a report submitted to it by the team responsible for managing the response. If approved, the NHS board should ensure that the report’s recommendations are forwarded to the relevant organisations with responsibility for taking them forward.When an outbreak affects more that one NHS board area, Health Protection Scotland has responsibility for coordinating the NHS boards which manage the public health response to an outbreak locally. It does so to ensure that the response is consistent and cohesive. It has responsibility for reporting on such outbreaks. The pandemic of influenza A(H1N1) was such an outbreak.This report sets out to:describe the pandemic in Scotland;present how it was monitored and investigated, risks assessed, control measures put in place, communications established and the health protection responders coordinated;indicate lessons learned;draw conclusions about how well objectives were achieved;recommend how Scotland can help improve the handling of a further pandemic or like event, the annual seasonal flu programme and health protection services in general.
