Diseases Caught by Breathing in the Germs

=1454. The more common diseases.= The following are some of the more
common diseases caught by breathing in the germs: Colds, diphtheria,
tonsilitis, grippe, scarlet fever, pneumonia, and consumption.

The germs that cause these diseases grow well in the dark, warm, moist
lining of the nose, throat, windpipe and lungs, and they are coughed
or sneezed out or blown out and float in tiny bubbles in the air or
fall to dry into dust which is blown about with the wind, and so are
breathed in, or they may be transferred directly by kissing invalids
and sick children.

=1455. How to avoid breathing in sickness.= Do not visit sick people
or a house where the children are sick.

Do not let other people cough or sneeze over your food or in your
face.

Do not allow others to spit on the floor of your squadron or tent.

Do not do these things yourself.

Blow your nose into a handkerchief that can be boiled or into a piece
of paper that can be burned.

[Illustration: Fig. 2

_Distributing sickness_]

Put your hand before your face when you cough or sneeze.

Rinse out the nose with hot, weak salt water at night and especially
if you have been inhaling dust.

Brush the teeth after each meal and before going to bed.

Do not pick the nose with the finger nails; it makes sore spots in
which germs grow.

On dusty hikes tie a handkerchief across the nose and mouth.

Never sweep the floor with a dry broom. Use a damp mop and so pick the
germs up and carry them out instead of driving them up in the air as
dust.

Diseases Caught by Swallowing the Germs

=1456. The more common diseases.= The following are some of the more
common diseases caught by swallowing the germs: Typhoid fever,
dysentery, cholera, and ptomaine poisoning.

=1457. Water as a distributer of disease.= Impure water is one of the
most common distributers of disease that there is. Therefore, water
from sources unknown or soiled by sewage, should be avoided as deadly
and should not be used, _unless boiled_, for drinking, brushing the
teeth or rinsing mess kits.

You can not always tell polluted water by its appearance, smell or
taste. Unless from a sewer or drain, it may look clear and sparkling,
with no smell and have a pleasant taste, so, w
