Measles is a disease of close association; hence its increase during the
colder months.

Frequently a child will go to a party and engage in innocent games in
which children are brought in close contact with one another. Perhaps
among the guests there is one with reddened, watery, eyes, which are
sensitive to light. The eyelids are perhaps a little puffy, and the guest
has a hard, high-pitched cough. The other children pay no attention to
this, and the games go on uninterruptedly. In this way a single child in
the beginning stages of measles may easily affect 15 or 20 others. This is
frequently the case when kissing games are played.

About 10 days later the children who have exposed themselves to the
disease begin to sicken. They, too, have red, watery, sensitive eyes and
puffy eyelids. In fact, in rather severe cases the whole face has a rather
swollen, puffed appearance. The throat feels parched and a dry, irritating
cough increases the discomfort. The child is apt to come home from school
feeling drowsy and irritable, not infrequently complains of chilly
sensations, and may even have a chill. At night the irritation increases,
the child is feverish, the whites of the eyeballs show little red lines
upon them, and the little sufferer has the appearance of being just ready
to cry.

If the anxious mother takes the child to the window in the morning, raises
the curtain, and examines the little one's throat she will see that the
hard palate and back of the throat are a dull, angry red. Perhaps there
are a few little red spots on the hard palate, and if the mother will look
closely at the lining membrane of the cheek she will see some small
white-tipped, reddish spots. These are called "Koplik's" spots, and are
one of the signs of measles.

The child is kept from school that day, and that night his fever is higher
than it was the night before. He rolls and tosses about the bed and wakes
up his mother a good many times to ask for a drink of water. This sort of
thing continues for 3 or 4 days; then, one morning when the child is
having its bath the mother sees some little dusky red spots along the hair
line. They look a good deal like flea bites. Within 24 hours this rash is
spread over the body and the child looks very much bespeckled and swollen.
In from 5 to 7 days the rash begins to fade, and within 3 or
