Is the 1918 flu pandemic responsible for the majority of Iranian casualties during the first world war (1917-1919)?
are the British (who were the a occupying power) responsible for it?
(because the people of Iran in those days did not have sufficient knowledge of infectious diseases and had probably never seen a microscope, so this must be one of the reasons that they did not know what was responsible for the majority of Iranian casualties during the first world war.)
