O ii The Canadian Pandemic Influenza Plan for the Health Sector Foreword and Acknowledgements The Canadian Pandemic Influenza Plan for the Health Sector maps out how the health sector can prepare for and respond to pandemic influenza in Canada. [...] The Canadian Pandemic Influenza Plan for the Health Sector is the product of extensive dialogue and collaboration within the Pandemic Influenza Committee (PIC). [...] As Co-Chairs of the Pandemic Influenza Committee, it has been a continually enriching experience to watch the document evolve, and to see the sheer amount of time, dedication and commitment poured into the maintenance of the Plan. [...] The Plan and the annexed guidelines, checklists and other documents were developed to assist all jurisdictions with the main components of health sector planning, including surveillance, vaccine programs, use of antivirals, health services, public health measures and communications. [...] The Centre for Infectious Disease Prevention and Control (CIDPC), Public Health Agency of Canada (PHAC), coordinated the development of this edition of the Plan in collaboration with the Centre for Emergency Preparedness and Response (CEPR), PHAC, with direction from the Pandemic Influenza Committee (PIC).
