In The Following Diseases Only The Affected Child Is Excluded

Erysipelas. Child should not return till all swelling and peeling of skin has disappeared.Ringworm on Scalp. Child should be excluded till cured. Very difficult to cure and often takes a very long time.
Ophthalmia. Child should not return till all traces have disappeared.Phthisis (Consumption). If in advanced stage and coughing much or spitting, child should be excluded. (Infection from breath and dried spit floating in the air as dust.)
Scabies or Itch. Child should be excluded until cured.
Ringworm on Skin. Child should be excluded till cured. This takes only a few days if properly treated.Impetigo (Contagious Sore). Child should be excluded until cured. A week or ten days should suffice.

Most people still think that colds are due to cold air or draughts rather than to a cold germ, which finds a body unequipped with resisting power, with its germ police off guard, exhausted from overwork, or disaffected and ready to turn traitor if the enemy seems stronger than our vitality. Sometimes it seems as if we contracted it from a sneezing fellow-passenger, sometimes from a draught from an open car window. An uninformed opponent of the theory that colds are a germ disease wrote the following letter last winter to a New York newspaper:

In addition to the Society for the Suppression of Noises there should be in this town a Society for the Suppression of "Fresh-Air" Fiends. The newspapers report an epidemic of pneumonia, grippe, and colds. It is almost entirely due to the fact that the average New Yorker is compelled to live, move, and have his being from daylight to midnight in a succession of draughts of cold air caused by the insanity of overfed male and female hogs, who, with blood almost bursting through their skins, demand "fresh air" in order to keep from suffocating. Everywhere a man goes, day or night, he is in a draught caused by the crazy ideas about fresh air.

Our wise ancestors, who as a rule lived much longer than we do, and had much better health, said:

"If the wind should blow through a hole, God have mercy on your soul."

After the correspondent has learned that our ancestors had more colds than we, had poorer health, and died twenty years younger, perhaps he will listen to proof that his unclean warm air weakens the body and makes it an easy prey to cold germs.

Many physicians preach and practice this fallacy as to fresh air and colds, but few physicians now deny that influenza is a germ disease or that a nose so irritated and so neglected as to secrete large quantities of mucus is a better place for breeding disease germs than a nose whose membranes are clean and not thus irritated.

Until medical specialists are agreed, and until they have definitely located the cold germ, we laymen must choose for ourselves a working theory. The weight of opinion at the present time declares that colds are due to germs. Strong membranes with good circulation and drainage provide poor food for germs. Congested membranes furnish proper conditions for propagation. The germ theory explains the spread of germs from the nose to the passages of the head, and from head to arteries and lungs.
