It is essential that everyone washes their hands more often, using soap and water for at least 20 seconds. Hand washing with soap employs mechanical action that loosens bacteria and viruses from the skin, rinsing them into the drain. Drying hands afterwards makes the skin less hospitable to the virus. Hand sanitiser can be effective if soap is not available or the situation makes using soap less feasible (i.e. when utside) but using hand sanitiser provides none of the virus-destroying friction that rubbing your hands together and rinsing with water provides.
Please see the latest guidance and video on handwashing from the NHS.
The e-Bug project is led by Public Health England and has a dedicated webpage for learning resources on hand washing and respiratory hygiene. E-Bug has published posters on hand hygiene, and covering coughs and sneezes, to display in bathrooms, classrooms and shared spaces.
