Abstract


Many infectious diseases can be transmitted through direct contact. If hands are contaminated with pathogens, especially when they are soiled with respiratory discharge or faecal matters, diseases include dysentery, cholera, hepatitis, influenza, and hand, foot and mouth disease can be spread easily. Observance of hand hygiene is the prerequisite of the prevention of the spread of communicable diseases. Using soap and water or rub hands with alcohol-based handrub can achieve hand hygiene.
Hand hygiene is the single most important measure of reducing the spread of diseases. Members of the public are advised to clean hands with liquid soap and water when they are visibly soiled or likely contaminated with blood and body fluid. When hands are not visibly soiled, could be cleaned them with 70-80% alcohol-based handrub.
In general, we should wash hands with soap and water when hands are visibly dirty or visibly soiled with blood, body fluid, after using the toilet or changing the diapers. When hands are not visibly soiled, 70-80% alcohol-based handrub is also an effective alternative.
According to the World Health Organization’s recommendation, most alcohol-based handrubs contain either ethanol, isopropanol or n-propanol, or a combination of two of these products.
How can we ensure hand hygiene performance are being conducted up to recommendation? How about night duties clinical colleagues, or in-a-hurry manner? A specially designed water basin with 7 steps reminder liquid-crystal display plus at least of 20 seconds hand washing times counting would be a better alternative to remind on good hand hygiene along with proper performance. Generalization of proper hand hygiene altitude by installing such on city around and all health care areas can reinforce the hand hygiene compliance.
