Influenza is spread by droplet infection/' that is, by little drops swarming with germ9 scattered by infected persons who sneeze, spit or cough in public places. One sneeze in a street car may infect a whole city. In order to guard against infection, therefore, it is necessary to keep the mouth and nose clean and healthy by means of some mild antiseptic and to treat all colds promptly. A wash composed of one teaspoonful boric acid, one teaspoonful bicarbonate of soda and one teaspoonful of common salt will be found very useful in keeping nose and throat clean. Treatment of the disease is simple. Surgeon-General Blue, of the United States Public Health Service, summarizes it as follows: Rest in bed, fresh air, abundant food, free action of intestines, with Dover's powder for the relief of pain. Every case with fever should be regarded as serious and kept in bed.
