Measles incidence estimations based on the notification by general practitioners were suboptimal.

Objective: The aim of this study was to determine the notification by general practitioners (GPs) to the Municipal Health Service (MHS) and the presentation of measles complaints by patients to the GP during a measles epidemic in a 78% vaccinated population.

Study Design And Setting: Measles cases in children under 13 years were identified via questionnaires, GPs' records, and MHS's records. Consultation rate, notification rate, and completeness of notification were determined.
