The federal government established the Fosdick Commission (under the American College of Surgeons) in April 1917 expressly to reduce alcohol abuse and venereal disease among the troops. "The rules are many and very strict," 15 restaurants have been shuttered. Public health officers have ordered that all barbers must show that have had a "successful smallpox and typhoid vaccination."  The regulations at Camp Dodge also apply in the city of Des Moines, Iowa.
