A new adaptation of the face mask in control of contagious disease

One of the most troublesome problems confronting the medical staff of the base hospitals in camps is the prevention of cross infections. A mistaken diagnosis in the examining room may place measles in a scarlet fever ward, or meningitis in a clean diagnostic ward. These mistakes are partially remedied by sending all doubtful patients to an observation ward, where they may be differentiated at leisure. The development of a secondary infection as a result of an exposure some time previous to entrance into the hospital is unavoidable.
