Meningitis and diphtheria are examples of diseases which are spread by carriers; that is by persons who are harboring the bacteria which causes these infections without being sick themselves. Such persons are said to be immune. These germs are carried in the nose and throat and are thrown out in the act of coughing, sneezing, spitting ad loud speaking, along with fine droplets of moisture, so small in fact that they are not noticed by the average individual. The spread of disease by this means has given rise to the term “droplet infection.”
It becomes a matter of extreme importance to eliminate meningitis carriers in a military camp. The close personal associations unavoidable in camp life render the carrier a distinct menace to his associates. The “carrier” surveys made by the laboratory department at Camp Cody last winter were for this purpose, and undoubtedly were of great help in keeping down the incidence of diphtheria and meningitis.
The water, milk and ice cream supplies had to be examined regularly in order to insure their purity. Occasionally certain articles of food have to be examined for disease producing germs.
The other class of work, that coming from the Camp Cody hospital, has to do with the diagnosis and treatment of patients. Blood counts, stomach examinations, Wassermann test, sputum examinations, etc., are all made for the help which they may give to the ward surgeon in the diagnosis of a given case. Some time laboratory findings are of very little importance or help; sometimes they are of very great help.
Last winter the personnel of the Camp Cody laboratory consisted of seven medical officers and fourteen enlisted men. At the time the enlisted men, being untrained in the branch of work, much of the routine had to be done by medical officers. Slowly but surely the enlisted men became able to take over more and more of the skilled technical work, and the need for officers decreased. The experience which sergeants Robinson and Weinstein have gained in the past year has fitted them to do nearly all the technical work in the Camp Cody hospital laboratory. In fact they have had a larger experience in this particular kind of work than many physicians have had. The other enlisted men Corporal Hafer, Private Heine, Groat and Black have had an especially good but rather brief training course in laboratory work at the Yale Army Medical school, and with this foundation are able to grasp the practical work very quickly. – The Deming Headlight – February 1919
