The role of general practice in contact tracing, in monitoring people in home isolation, and in distributing antiviral drugs is unclear in most plans. Home care by GPs for people in quarantine is mentioned in two US Plans [50, 51] , and one English plan [36] , though the recently released guidelines for PCTs anticipate a role for general practices in home care [52] . In all country plans, dispensing antiviral medications was generally performed by public health units. Only 22% of PCT plans and 40% of US plans mention a role for primary care in dispensing antiviral medications. None of the Canadian plans, and only one NZ and two Australian state plans, mentioned antiviral dispensing by primary care. The only plan to set out contingencies when decisions about dispensing may change was one Canadian RHA plan [27] . Although immunisation was mentioned most frequently after surveillance as a public health activity by general practices, in most plans the immunisations were against pneumococcal disease and seasonal influenza, but not mass immunisations against pandemic influenza.
