If it is necessary to enter a sick room, particularly where there is
fever, these simple rules should be observed to avoid contagion. Never
enter fasting. At least take a few crackers or some such simple food
before going in. Do not stand between the patient and the door where the
current of air would naturally strike you. Avoid sitting on or touching
the bed clothes as much as possible, and do not inhale the patient’s
breath. The hands should always be washed in clean water before leaving
the room, in order not to carry infection by them to other people or
things you may need to touch. After visiting a fever patient change the
clothes if possible. As soon as a fever is over and the patient is
convalescent, the dress which has been used by the nurse should be
fumigated in the same manner as the bedding, as already explained.
