Several infectious diseases can be spread by contaminated hands. Hand washing, also referred to as hand hygiene, is the basic requirement for an individual to lead a healthy life. The simple act of washing hands properly and regularly can help prevent the spread of many diseases, especially among children, and is the basic form of prevention against any infection. Hand washing with soap consistently at critical moments during the day prevents the spread of diseases like diarrhoea and cholera. Sustaining a hand-wash practice is very important, and consistency leads to efficiency. Studies have shown that improved hand-washing practices can lead to improvements in growth in children under the age of five. Therefore, irrespective of whether one is in India or anywhere else in the world, the importance of inculcating a hand-wash culture is a top priority for everyone.
