In the United States, the disease was first observed in Haskell County, Kansas, in January 1918, prompting local doctor Loring Miner to warn the U.S. Public Health Service's academic journal.
On 4 March 1918, company cook Albert Gitchell reported sick at Fort Riley, Kansas. By noon on 11 March 1918, over 100 soldiers were in the hospital.[31] Within days, 522 men at the camp had reported sick.[32] By 11 March 1918 the virus had reached Queens, New York.[33] Failure to take preventative measures in March/April was later criticised.[5]
