Surveillance of incident influenza-like illness (ILI) was implemented in two children and adult medical emergency departments during the influenza A (H1/N1) pandemic to assess correlations in the daily number of ILI-related emergency room visits (ERV) between these departments. A total of 7165 ILIs in children and 610 ILIs in adults were observed. We noticed a high linear correlation between the number of ERV involving ILI on day D in the pediatric department and the number of ERV because of ILI 2 days later in adults (R = 0*82, P < 10(-4)). Therefore, the rate of adult ILI-related ERV might be anticipated based on the rate of pediatric ERV.
