Estimates concerning the proportion of symptomatic cases seeking medical care from their GPs/hospital emergency departments and being hospitalized were based on data collected from the weekly phone surveys. The proportion of cases admitted to ICUs or dying during hospitalization was obtained from surveillance data. Symptomatic H1N1 case estimates were based on ILI-38 definition (ILI-38: fever >38°C and cough or sore throat).
