Influenza poster,1918. Poster displayed in American theatres during 1918,providing information about the influenza pandemic. During and after the First World War,there was a global influenza pandemic,known as the Spanish Flu (1918-1919). A fifth of the world's population was infected,and between 20 and 50 million people died. Such pandemics occur when a new infectious virus appears for which the human population has no immunity. This can happen when there is a major change in the surface proteins of an existing virus. This poster is from Chicago,USA | |
