World Hand Hygiene Day takes place on May 05, 2015. The day is declared by the World Health Organization (WHO) and encoures patients and their family members to join health workers in their efforts to practice good hand hygiene. According to WHO, every year, hundreds of millions of patients around the world are affected by health care-associated infections. More than half of these infections could be prevented by caregivers properly cleaning their hands at key moments in patient care.
Hand hygiene is the act of cleaning ones hands with or without the use of water or another liquid, or with the use of soap, for the purpose of removing soil, dirt, and/or microorganisms. Medical hand hygiene pertains to the hygiene practices related to the administration of medicine and medical care that prevents or minimizes disease and the spreading of disease. The main medical purpose of washing hands is to cleanse the hands of pathogens (including bacteria or viruses) and chemicals which can cause personal harm or disease.
Hand hygiene is especially important for people who handle food or work in the medical field, but it is also an important practice for the general public. People can become infected with respiratory illnesses such as influenza or the common cold, for example, if they don't wash their hands before touching their eyes, nose, or mouth.
