ABSTRACT
Approximately ninety two years ago, the worst influenza pandemic or "Spanish flu" occurred in 1918, at the end of the First World War [WWI, 1914-1918] which resulted in the deaths of millions of people worldwide. The death toll exceeded the total number of victims of WWI. The 1918 Spanish flu was a deadly, major global event that affected many countries, including Iran. In Iran, it was accompanied by a high mortality rate estimated to be more than one million. However, detailed information on the impact of this outbreak in Iran is scarce. The present paper describes a brief history of the influenza pandemics in the world as well as the spread of the 1918 Spanish flu to Iran
