Chapter VIToC

Catching Diseases, Colds, Diseased Glands

Deadly fevers, the plague, black death, cholera, malaria, smallpox, taught mankind invaluable lessons. Millions of human beings died before the mind of man devoted itself to preventing the diseases for which no sure cure had been found. Efforts to conquer these diseases were tardy because men were taught that some unseen power was punishing men and governments for their sins. The difference between the old and the new way is shown powerfully by a painting in the Liverpool Gallery entitled "The Plague." A mediæval village is strewn with the dead and dying. Bloated, spotted faces look into the eyes of ghouls as laces and jewelry are torn from bodies not yet cold. In the foreground a muscular giant, paragon of conscious virtue, clad like John the Baptist and Bible in hand, finds his way among his plague-stricken fellow-townsmen, urging them to turn from their sins. Modern efficiency learns of the first outbreak of the plague, isolates the patient, kills rats and their fleas which spread the disease, thoroughly cleanses or destroys, if necessary, all infected clothing, bedding, floors, and walls, and makes it possible for us to go on living for each other with a better chance of "bringing forth fruits worthy for repentance."

Where boards of health make it compulsory to report cases of sickness due to contagion, health records are a reliable index to "catching" diseases. But now that the chief infection is the kind that afflicts children, we can read the index before the outbreak that calls in a physician to diagnose the case. School examination shows which children have defects that welcome and encourage disease germs. It points to homes that cultivate germs, and consequently menace other homes. To locate children who have enlarged tonsils may prevent a diphtheria epidemic. To detect in September those who are undernourished, who have bad teeth, and who breathe through the mouth will help forecast winter's outbreaks of scarlet fever and measles. One dollar spent at this season in examination for soil hospitable to disease germs may save fifty dollars otherwise necessary for inspection and cure of contagious diseases.

It is harder at first to interest a community in medical examination than in medical inspection, because we are all afraid of "catching" diseases, while few of us know how they originate and how they can be prevented by correcting the unfavorable conditions which physical examination of school children will bring to light.

Courses in germ sociology are therefore of prime necessity. How do germs act? On what do they live? Why do they move from place to place? What causes them to become extinct? With few exceptions, germs migrate for the same reason as man,—search for food, love of conquest, and love of adventure. When there is plenty of food they multiply rapidly. Full of life, overflowing with vitality, they move out for new worlds to conquer. Like human beings, they will do their best to get away from a country that provides a scanty food supply. Like men and women, they starve if they cannot eat. Like boys and girls, they avoid enemies; the weak give way to the strong, the slow to the swift, the devitalized to the vitalized.

Human sociology imprisons, puts to death, deprives of opportunity to do evil, or reforms those who murder, steal, or slander. Germ sociology teaches us to do the same with injurious germs. We imprison them, we take away their food supply, we kill them outright, or we starve them slowly. They have a peculiar diet, being especially partial to decomposing vegetable and animal matter and to what human beings call dirt. By putting this diet out of their reach we make it impossible for them to propagate their kind. By placing poison within their reach or by forcing it upon them we can successfully eliminate them as enemies. As the president of Mexico restored order "by setting a thief to catch a thief," so modern science is setting germs to kill germs that harm crops and human stock. Of utmost consequence is it that the body's germ consumer—its pretorian guard—be always armed with vitality ready to vanquish every intruding hostile germ. If we are false to our guard, it will turn traitor and join invaders in attacking us. But here, as in dealing with evils that originate with human beings, an ounce of prevention is worth a ton of cure. The most effectual way to eliminate germ diseases is to remove the cause—the food supply of disease germs. The fact that many germs are plants, not animals, does not weaken the analogy, for weeds do not get a chance in well-tilled soil.

Perhaps the most notable recent example of government germ extermination is the triumph over the yellow-fever and malaria mosquito in Panama. When the French started to build a canal in Panama, the first thing they did was to build a hospital. The hospital was always full and the canal was given up. At the time the United States proposed to re-attempt the work, it was thought that it could not be done without great loss of life and without great labor difficulties. Instead of taking the sickness for granted and enlarging the French hospital, the chief medical inspector, Gorgas, took for granted that there need be no unusual sickness if proper preventive measures were taken. He knew what the French had not known, that the yellow-fever scourge depends for its terrors upon mosquitoes. Accordingly, with the aid of six thousand men and five million dollars he set about to starve out the few infected and infectious kinds of mosquito,—the yellow-fever or house mosquito and the malaria or meadow mosquito. He introduced waterworks and hydrants, paved the streets, drained the swamps and pools in which they breed, and instituted a weekly house-to-house inspection to prevent even so much as a pail of stagnant water offering harbor to these enemies. The grass of the meadows where the malaria mosquito breeds was cut short and kept short within three hundred feet of dwellers,—as far as the mosquito can fly. All ditches were disinfected with paraffin, and the natives were forced to observe sanitary laws. President Roosevelt, in his special message to Congress on the Panama Canal in 1906, stated that in the weekly house-to-house visit of the inspectors at the time he was in Panama but two mosquitoes were found. These were not of the dangerous type. As a consequence of this sanitary engineering there is very little sickness in Panama, the hospital is seldom one third full, and the canal is progressing very much faster than was expected. Panama, like Havana, is now safer than many American cities, because cleaner and less hospitable to disease germs.

Any place where numbers of people are accustomed to assemble favors the propagation of germs,—whether it be the meetinghouse, the townhall, the theater, or the school. Every teacher can be the sanitary engineer of her own schoolroom, school, or community by coöperating with the school doctor, the town board of health, family physicians, and mothers. Every teacher can exterminate disease by applying the very same principles to her schoolroom as Chief Medical Inspector Gorgas applied to Panama. Knowledge, disinfection, absolute cleanliness, education, and inspection are the essential steps. First she must know that "children's diseases" are not necessary. She should discountenance the old superstition that every child must run the gamut of children's diseases, that every child must sooner or later have whooping cough, measles, chicken pox, mumps, scarlet fever, just as they used to think yellow fever and cholera inevitable. The price of this terrible ignorance has been not only expense, loss of time, acquisition of permanent physical defects, and loss of vitality, but, for the majority of children, death before reaching five years of age. All these "catching" diseases are germ diseases, which disinfection can eliminate. The free use of strong yellow soap and disinfectants on the school floor, windows, benches, desks, blackboards, pencils, in the coat closets and toilets, plus the natural disinfectants, hot sun and oxygen, will prevent the schoolroom from being a source of danger. One or more of these germ-killing remedies must be constantly applied; cleansing deserves a larger part in every school budget.

Often country towns are as ignorant of the existence of germs and of the means of preventing the spread of disease as the woman in a small country town who used daily to astound the neighbors by the "shower of snow" she produced by shaking the bedding of her sick child out of the window. Their astonishment was soon changed to panic when that shower of snow resulted in a deadly epidemic of scarlet fever. Medical inspection of New York City's schools was begun after an epidemic of scarlet fever was traced to a popular boy who passed around among his schoolmates long rolls of skin from his fingers.

Much of the care exercised at school to prevent children's diseases is counteracted because children are exposed at home and in public places to contagion, where ignorance more often than carelessness is the cause of uncleanliness. By hygiene lessons, illustrating practically the proper methods of cleaning a room, much may be done to enlist school children in the battle against germs. Through the enthusiasm of the children as well as through visits to the homes parents may be instructed as to the danger of letting well children sleep with sick children; the wisdom of vaccination to prevent smallpox, of antitoxin to prevent serious diphtheria, of tuberculin tests to settle the question whether tuberculosis is present; why anything that gathers dust is dangerous unless cleansed and aired properly; and why bedding, furniture, floor coverings, and curtains that can be cleansed and aired are more beautiful and more safe than carpets, feather beds, upholstery, and curtains that are spoiled by water and sunshine; how to care for the tuberculous member of the family, etc. Anti-social acts may be prevented, such as carrying an infected child to the doctor in a public conveyance, thereby infecting numberless other people; sending infected linen to a common laundry; mailing a letter written by an infected person without first disinfecting it; sending a child with diphtheria to the store; returning to the dairy unscalded milk bottles from a sick room.

The daily inspection of school children for contagious diseases by the school physician has, where tried, been found to reduce considerably the amount of sickness in a town. Such inspection should be universally adopted. Moreover, the teacher should be conversant with the early symptoms of these diseases so that on the slightest suspicion the child may be sent home without waiting for the physician's call. Like the little girl who never stuttered except when she talked, school children and school-teachers are rarely frightened until too late to prevent trouble. The "easy" diseases such as measles, whooping cough, etc., cost our communities more than the more terrible diseases like typhoid and smallpox. During one typical week ending May 18, 630 new cases of measles were reported to one department of health. Obviously the nineteen deaths reported give no conception of the suffering, the cost, the anxiety caused by this preventable disease. The same may be said of diphtheria and croup, of which only thirty-two deaths are reported, but 306 cases of sickness. Yet no one to-day will send a child to sleep with a playmate so as to catch diphtheria and "be done with it."

The most strategic point of attack is almost universally unrecognized. That is the child's mouth. Here the germs find lodgment, here they find a culture medium—at the gateway of the human system. The mouth is never out of service and is almost never in a state of true cleanliness. Solid particles from the breath, saliva, food between the teeth, and other débris form a deposit on the teeth and decompose in a constant temperature of ninety-eight degrees Fahrenheit. In the normal mouth from eight to twenty years of age the teeth present from twenty to thirty square inches of dentate surface, constantly exposed to ever-changing, often inimical, conditions. This bacterially infected surface makes a fairly large garden plot. Every cavity adds to the germ-nourishing soil. Dental caries—tooth decay—is a disease hitherto almost universal from birth to death. Thus the air taken in through the mouth becomes a purveyor of its poisonous emanations and affects the lung tissues and the blood. Food and water carry hostile germs down into the stomach. Thence they may be carried into any organ or tissue, just as nourishment or poison is carried.

Moreover, the child with an unclean mouth not only infects and reinfects himself but scatters germs in the air whenever he sneezes or coughs. In a cold apartment where there is no appreciable current of air a person can scatter germs for a distance of more than twenty-two feet. Germs are also scattered through the air by means of salivary or mucous droplets. It is this fact that makes colds so dangerous.
