Influenza is a major public health problem. Some cases occur every winter; there have been six substantial epidemics in the United Kingdom during the past 25 years; pandemics following major shifts in the influenza virus occur less frequently but are particularly severe.1
Most European countries support programmes of influenza surveillance.2 In some countries—for example, France,3 the Netherlands, and Portugal—clinical and virological surveillance is undertaken in sentinel practices that monitor the incidence of influenza and obtain specimens for virological examination in the major virological laboratories. In the United Kingdom the largest clinical surveillance network is the Royal College of General Practitioner's weekly returns service.4 Virological surveillance is based on the results of virological tests in patients admitted to hospital, with centralised reporting to the Public Health Laboratory Service.
