Prevention is based on the translation of the
knowledge of the mechanism of transmission
79
  • Not only should you take action to protect
    yourself and your families, you should also take
    action to prevent the spread of influenza if you
    or anyone in your family becomes ill
  • George W. Bush
  • The White House
  • November 1, 2005

80
National strategy for pandemic influenza
  • Individual citizens should be prepared for an
    influenza pandemic and be educated about
    individual responsibility to limit the spread of
    infection if they or their family members become
    ill.

81
Responsibilities of the Government
  • Provide guidance to individual on infection
    control behaviors they should adopt pre-pandemic
    and the specific actions they will need to take
    during a severe influenza season or pandemic,
    such as self-isolation and protection of others
    if they themselves contract influenza.

82
One of the component of containing outbreaks
  • Emphasize the roles and responsibilities of the
    individual in preventing the spread of an
    outbreak and the risk to others if
    infection-control practices are not followed

83
Individuals and Families
  • Individual action is perhaps the most important
    element of pandemic preparedness and response
  • Responsibilities of the individual and families
    include taking precautions to prevent the spread
    of infection to others if an individual or a
    family member has symptoms of influenza
