I haven't found a lot of numbers specifically for British Persia, but it is amost certianly the case that far more subjects of that area died from the Spanish Flu (50-100 million killed world-wide) rather than WWI (about 16 million killed, mostly in Europe and Africa). Even among the heaviest combatants, the the numbers were close (eg: UK 1 mil for war, 250K for the Flu, France 1.7 mil for war, 400K for the Flu)
The flu was a pandemic, that hit every corner of the globe hard. People like to try to blame these things on someone, but that's really unrealistic. Certinaly the British were no more at fault that the Chinese (an early theory had it originating there), or Kansans. Certianly there was nothing they could have done to stop it even if they tried. People on isloated Pacific islands died off (8% of the population of Tonga) every bit as much as folks in well-traveled crossroads.

Flu is caused by a virus. A virus is too small for an optical microscope.
The 1918 flu pandemic was neither caused nor spread by humans intentionally (although some nations uses quarantine to good effect).
Humans still have no effective flu treatment.
Blaming the British for Iranian deaths from the pandemic is preposterous. The British did not quarantine any part of the Empire from the rest, so why would they be expected to do that in Persia?
