| Mild or modified smallpox is as infectious as | | severe type. | -------------+--------------------------------------------------+ SORE THROAT, | Often leads to serious results, affections of | ACUTE, | heart, kidneys, etc. Very apt to occur in | SEPTIC | epidemics due to milk contaminated by a | | patient suffering from the disease. | -------------+--------------------------------------------------+ WHOOPING | After effects often very severe and disease | COUGH | causes great debility.

DISINFECTION: The cleansing and disinfection of the person includes washing the entire body and the hair with soap and water; thorough brushing of the teeth; rinsing the mouth; gargling the throat, and douching and spraying the nose with an antiseptic solution; and finally, a complete change of clothing (or a change of underwear and a thorough shaking and brushing of the outer garments out of doors before these are put on again). (_Facing p. 247_) It may be added that the ways by which poliomyelitis, or infantile paralysis, is spread are not definitely known at the time of writing. We are justified, however, in believing that investigation now in progress will make exact information available in the near future. "The weight of present opinion inclines to the view that poliomyelitis is exclusively a human disease, and is spread by personal contact, whatever other causes may be found to contribute to its spread. In personal contact we mean to include all the usual opportunities, direct or indirect, immediate or intermediate, for the transference of body discharges from person to person, having in mind as a possibility that the infection may occur through contaminated food. "The incubation period has not been definitely established in human beings. The information at hand indicates that it is less than two weeks, and probably in the great majority of cases between 3 and 8 days."--(Report of Special Committee on Infantile Paralysis, American Journal of Public Health, November 1916.)
