Whatever the nature of a malady, so soon as it is pronounced to be infectious the same precautions should in all cases be taken. Let it at once be decided who is to nurse the patient, and make all arrangements by which nurse and patient may be isolated from the rest of the household. If possible, 2 rooms communicating should be given up to them, and over the outer doors of these rooms sheets should be hung, which must be kept constantly saturated with disinfectants, either Condy’s fluid or carbolic acid in water. No servant in communication with the rest of the household must enter the sickroom; if she does so, she should be isolated like the nurse, and any message that may require to be given must be spoken through the sheet. The best plan is to have a regular nurse from one of the many excellent institutions which provide them; they make the patient more comfortable, take entire charge of the arrangement of the sickroom, and know exactly what is required to be done in an emergency, and for disinfection. At the very commencement all curtains should be taken down, and at once sent out of the house to be disinfected by properly qualified persons; the same course should be pursued with the carpets (woollen articles hold infection beyond any others), and then the floors can be kept sprinkled with disinfectants, besides having a broom steeped in them passed over every morning. Linen used in the sickroom should always be put into water with either carbolic or Condy, before leaving the room; but, even with this precaution, it is far better to send it to be disinfected than to allow it to go to a laundry. The windows should be open, top and bottom, but more especially at the top, during the entire day, and if possible at night also; a thorough draught through the room is most desirable, if the patient can be kept out of the direct line of it. As much as possible, all cups, basins, jugs, and glasses should be kept upstairs; but those that must occasionally be sent down should be carefully washed in Condy and water, and at once placed outside the door, and again passed through disinfectant on their arrival downstairs. The clothes that may have been worn for the day or two before the disease absolutely declared itself should be sent for disinfection, but those which have only been in casual contact may be disinfected at home. A small room should be chosen for the purpose, and the dresses, petticoats, shawls, or other articles hung up, so as to be fully exposed. The doors, windows, and all other apertures must be kept closed, and the disinfection may be effected either by chlorine, which is formed by pouring hydrochloric acid on chlorate of potash, or else by burning sulphur. In either case the quantity must be sufficient to render the atmosphere of the room unbearable to a human being, or otherwise the disease germs will not be destroyed. The bedding and blankets must be sent for proper disinfection at the close of the illness. Nothing should be kept in the room except for use. Clothes in a wardrobe under such circumstances have been known to spread infection 10 years after. Handkerchiefs should be replaced by rags, burnt when used. Letters from the patient should be backed, or written on postcards dipped in carbolic; they are capable of spreading disease otherwise. A thing in which people are often lamentably careless is in allowing books that have been used by the patient to be afterwards used by others. It cannot be too often impressed on the minds of those who have to do with illness, that every book, paper or magazine used by an infectious patient must be burnt without leaving the sickroom. Infection is very often spread by allowing books from a circulating library to be returned to it after use by a person suffering from an infectious disorder.
Infection ceases in the individual as soon as the skin has thoroughly peeled—a process which takes a longer or shorter time in different individuals. The danger after this lies in the clothes, furniture, and rooms, and if these are at once thoroughly disinfected all danger is absolutely at an end. It is impossible to reprobate too strongly the conduct of those who wish and endeavour to shirk the expense and trouble of proper disinfection. It would be well if in such cases doctors would always avail themselves of their power to report the existence of a case of infectious disease to the sanitary officer of the district, when official pressure would at once be brought to bear, and all that is necessary be effected under compulsion.
The cured patient on the day of leaving home should go into a fresh room to dress, and put on things either new or disinfected, not returning to the sickroom. Brushes and sponges, as coming most in contact with hair and skin, are best destroyed. While a patient is in the infectious stage it is best that no letters should be written; but if, as is sometimes the case, some communication in writing must be made, danger is obviated by holding the paper and envelope in the fumes of chlorine.
A few words would not be amiss respecting those in the house who do not enter the sickroom. However great the precautions taken, the air of a house in which there is a case of infectious disease can never be absolutely safe, and it is far better to err on the side of caution than the reverse. Visitors should not be allowed to enter the house, and it is far better and more honest for the servants to state clearly at the door what disease is in the house. Special attention should be paid to the health of each member of the household. Any slight disorder is liable to predispose to infection.
There is a great variety of good disinfectants, and as many different ways of using them. A good plan, both effective and economical, is as follows:—Freely use moistened chloride of lime all through the house, and even in the sickroom, if the fumes are not found to be irritating; secondly, place in various parts of the room 5 or 6 soup-plates, or other flat vessels, containing Condy’s fluid; or hang about in the room as many perforated boxes filled with solid iodine; thirdly, keep the windows opened freely but the doors as seldom as possible; guard it both inside and outside with a large sheet, hung up to at least the height of the door, and at about 1 ft. distant from it, and kept constantly well moistened with a solution of carbolic acid (strength, about 1 of the acid to 40 of water); and, most important of all, receive as soon as possible all discharges, excreta, soiled linen, and all such matters, in vessels containing a strong solution of Condy’s fluid, chloralum, or carbolic acid. Many infectious diseases have (in addition to their common property of infecting the air through the effete products of respiration from the lungs and skin) some special channel of transmission. In cholera, typhoid (enteric) fever, and, in a less degree, typhus and relapsing fevers, it is principally by the excreta from the bowels and kidneys. These should be received at the very moment of their issue from the body into vessels fully charged with disinfectants. In diphtheria, it is by the throat. In erysipelas, hospital gangrene, and puerperal fever, by discharges peculiar to each. In smallpox, by pustular exudation from the skin. In scarlet fever, measles, &c., by desquamation (peeling off of the skin), rendered harmless by slightly moistening the surface of the body once or twice a day with ordinary olive oil or camphorated oil, or a weak solution of glycerine and carbolic acid. Never mix disinfectants; for instance, Condy’s fluid and carbolic acid act in precisely opposite ways, and might decompose each other.
The nurse must not neglect proper precautions for her own safety. She should use disinfectants freely about her own person, be sure that she has a sufficient quantity of undisturbed rest and regular meals, and avoid coming into unnecessary close contact with the patient. She should at once give up the occupation if she feel her general health at all injured. She must also be careful not to undertake a non-infectious case after being in attendance upon an infectious one for a considerable time; and until she has put herself through a complete process of disinfection, and done the same with all clothes worn at the time which she has not discarded altogether. Nothing must induce her to go near a confinement for several (at least 3) months.
Disinfection.—The most useful agents for the destruction of spore-containing infectious materials are:—
(1) Fire: Complete destruction by burning.
(2) Steam under pressure: 230°F. for 10 minutes.
