Cold season is just around the corner, are you prepared? Do you have your cough and cold remedies, cough drops, facial tissue, etc.? These are commonly thought of as the goto's, while a more common and effective treatment simply stopping the spread of germs by proper hand washing.
"According to the CDC, the simple act of handwashing is the single most important means of preventing the spread of viral and bacterial infections." Long before the CDC made this statement, Ignaz Semmelweis postulated that by washing hands before delivering a baby, the incidence of childbed fever (septaceamia fever) reduced significantly. Semmelweis, a 19th century hungarian physician, believed that aseptic techniques could help prevent the spread of sickness, and he was right. Louis Pasteur released his germ theory of disease which was influenced from Semmelweis.
Amazingly 80% of infectious diseases are transmitted by touch. Many Americans use a public restroom and do not wash their hands before leaving. They forget to wash before preparing meals and they forget before having a snack. A simple hand shake transmits germs to others, and the spread of infectious disease(s) occurs.
What can we do to prevent the spread of infectious disease such as colds? Well, we can all start off by washing our hands in warm soapy water. A traditional hand soap is fine. Through the friction of rubbing your hands together in warm soapy water, you will greatly decrease the number of bacteria, thus greatly reducing your chances of infection.
In addition to traditional handwashing, the CDC recommends the use of alcohol-based hand rubs. These rubs greatly decrease the number of microbes on our skin and do so in a rapid manner causing less skin irritation from rubbing. Though they smell and may cause dryness, hand sanitizers are a great way for us to combat microbes and the spread of infectious disease.
Remember, we all have bacteria resident on our skin. These bacteria, for the most part, are unharmful to us. The ones we should be concerned about, transient bacteria, reside above the layer of oil our body secretes, and these can raise our chances of contracting illness as they can be transferred with ease. The easiest and best sense way to remove transient bacteria is to wash your hands.
