The so-called communicable dis-eases are quarantinable and should be reported to the proper health authorities in the states requiring such procedure, in compliance with the law. There are certain sanitary and hygienic measures that should be used from a standpoint of pure cleanliness and common decency. The hygienic measures ordinarily recommended may be summed up as follows: The stools, urine, sputum and other excretions should be thoroughly disinfected. The urine may be disinfected by adding bichloride to make a solution of one to one thousand or by adding 10% formalin and allowing the solution to stand for an hour or so. It is more difficult to disinfect fecal matter. The masses should be thoroughly broken up and disinfected with bleaching powder, 3%. A 5% solution of carbolic acid may be used or formalin 10%. Another easy and effective way is to add enough hot water to cover the entire stool and then add a cup of unslacked lime or about one-fourth as much lime as bulk. The receptacle should then be covered and allow to stand for a couple of hours. In this way there will be enough heat generated by the lime to destroy the microörganisms. The sputum should be burned. It is recommended that the bed linen, towels and handkerchiefs used by the patient be disinfected by immersing for at least an hour in a solution of bichloride of mercury, one to one thousand, a 5% solution of carbolic acid, or 10% solution of formalin. Chiropractic Cause of So-called Communicable Dis-eases Chiropractically the cause of the so-called communicable dis-eases is interference with the transmission of mental impulses, which results in lack of function. Where there is an interference with the functions resulting in abnormal metabolism there is always an accumulation of waste products and poisons. The accumulation of the waste products and the correspondingly lowered resistance in these structures provide a fertile field for the growth and development of the bacteria that are found in the particular incoördination. These germs are present as scavengers for the sole purpose of consuming the waste material and these bacteria will disappear as soon as the subluxated vertebrae are adjusted and the tissues become normal, for they can not live on normal tissue and will be excreted as waste. However, if there are subluxations which interfere with the transmission of mental impulses resulting in lack of functions in the body and microörganisms are allowed to enter the body, the abnormal tissues will furnish them with food and a proper culture medium in which to develop. From a chiropractic standpoint the best prophylaxis is adjustments to restore transmission to normal and the germs will find no food or fertile field in which to develop and will be excreted as so much material that can not be used in the metabolism of the body.
