sons often get and spread the disease, and sometimes
die from it. Mild cases in adults may cause fatal cases among children.
Unless your services are needed keep away from the disease yourself. If
you do visit a case, bathe yourself and change and disinfect your clothing
and hair, beard, if any, and hands before you go where there is a child.
Do not permit any person or thing or a dog or cat, or other animal to come
from a case of scarlet fever to a child. No cat or dog should be permitted
to enter the sick room.

Do not permit a child to wear or handle clothing worn by a person during
sickness or convalescence from scarlet fever.

Beware of any person who has sore throat. Do not kiss or come near to such
a person. Do not drink from the same cup, blow the same whistle, or put
his pen or pencil in your mouth. Whenever a child has sore throat and
fever, and especially when this is accompanied by a rash on the body, the
child and attendant should immediately be isolated until the physician has
seen it and determined whether it has scarlet fever. Strict quarantine
should be established and maintained throughout the course of the disease.
Exposed persons should be isolated until such time has elapsed as may
prove that they are not infected. The period of incubation, that is the
interval of time between exposure to the contagion of scarlet fever and
the first sign of the disease in the person so exposed, varies. In many
cases it appears in seven days, in some cases in fourteen days, and in
some cases twenty-one days; the average period is about nine days.
Quarantine of persons exposed should not be raised under four weeks.

Children believed to be uninfected may be sent away from the house in
which there is scarlet fever to families in which there are no persons
liable to the disease, or to previously disinfected convalescent wards in
hospitals; but in either case they should be isolated from the public
until the expiration of the period of incubation. This time may vary, but
for full protection to the public isolation should be observed for four
weeks.

Persons who are attending upon children or other persons suffering from
scarlet fever, and also the members of the patient's family, should not
mingle with other people nor permit the entrance of children into their
house.
