Due to its high mortality rates this pandemic is often highlighted as a warning sign for what may happen during a future pandemic. After a short introduction into the problematic status of the validity of retrospective diagnoses the history of influenza pandemics is discussed. The pandemic of 1918 is analysed from the perspective of the public health system being connected to and relying on medical and scientific debates.
