The importance of hand washing
Hand washing is the easiest and the most effective way to prevent the spread of infection.
Proper hand washing requires the use of an antimicrobial soap. With vigorous friction and use of antimicrobial soap, 10-20 seconds is sufficient. The CDC(centers of disease control) recommended washing the hands for at least 10 seconds.
Disinfection is the process of destroying pathogens on non-disposable items that become contaminated. An object is usually cleaned with soap and water before disinfection.
Sterilization: The most common sterilization method requires bringing the object to a very high temperature, under pressure, for a period of time. The objective is to kill all microorganisms.
