The most important tool to use for influenza prevention is Vitamin D in all ages, but especially in children and the elderly. The Sacramento Bee published a good list of useful tips for avoiding the flu. Using an aerosol machine can reduce the spread of viruses and bacteria. A small study involving 11 people found that some people exhale larger amounts of germs than the others when they are sick. A six-minute aerosol treatment using salt-water demonstrated that the numbers of viruses or bacteria being exhaled was sharply reduced—by a whopping 72 percent—for up to six hours. Researchers concluded that, even though the study was small, the administration of a nebulized saline solution could dramatically reduce spread of infection. Homeopathy is a wonderful tool for preventing – and treating – the flu. And of course, one of the most important ways to prevent the flu is to wash your hands.
In 1864, the first steam-driven nebulizer was invented in Germany. This inhaler, known as "Siegle’s steam spray inhaler", used the Venturi principle to atomize liquid medication, and this was the very beginning of nebulizer therapy. The importance of droplet size was not yet understood, so the efficacy of this first device was unfortunately mediocre for many of the medical compounds. The Siegle steam spray inhaler consisted of a spirit burner, which boiled water in the reservoir into steam that could then flow across the top and into a tube suspended in the pharmaceutical solution. The passage of steam drew the medicine into the vapor, and the patient inhaled this vapor through a mouthpiece made of glass.
