- Wave of InfluenzaConcentrated occurrence of influenza infections. It is a characteristic of flu that it occurs more frequently at certain times in certain areas, so that an increase in influenza cases each year in the winter months can be expected. Spreading of the disease over several countries or continents (pandemic) is observed at intervals of decades. Pandemic waves of influenza included the 'Russian Cold', the 'Spanish Flu ', the 'Asiatic Flu ' and the 'Hong Kong Flu'. At the centres of an epidemic, the probability of disease is ca. 30 %; in pandemic areas it is higher.
