INFECTIOUS DISEASE PROPAGATION.

In view of the alarming prevalence of scarlet fever in many parts of

the country, the following hints by the _British Medical Journal_ are

wholesome warnings: "There are three common ways by means of which

infectious diseases may be very widely spread. It is a very usual

practice for parents to take children suffering from scarlet fever,

measles, etc., to a public dispensary, in order to obtain advice and

medicines. It is little less than crime to expose, in the streets of a

town and in the crowded waiting room of a dispensary, children

afflicted with such complaints. Again, persons who are recovering from

infectious disorders borrow books out of the lending departments of

public libraries; these books, on their reissue to fresh borrowers,

are sources of very great danger. In all libraries, notices should be

posted up informing borrowers that no books will be lent out to

persons who are suffering from diseases of an infectious character;

and that any person so suffering will be prosecuted if he borrow

during the time of his illness. Lastly, disease is spread by tract

distributors. It is the habit for such well meaning people to call at

a house where a person is ill and to leave him a tract. In a week or

so the tract is called for again, another left in its place, and the

old one is left with another person. It needs not much imagination to

know with what result to health such a practice will lead if the first

person be in scarlet fever or smallpox."

Dr. Hutton offers "a warning on the reckless manner in which parents

allow their healthy children to run into the houses of acquaintances

who have members of their families suffering from scarlatina, etc.,

and states that he has seen the infection thus carried from the

patient, and several families attacked."
