- after using the toilet or changing a nappy
- before and after handling raw foods like meat and vegetables
- before eating or handling food
- after blowing your nose, sneezing or coughing
- before and after treating a cut or wound
- after touching animals, including pets, their food and after cleaning their cages
Washing your hands properly removes dirt, viruses and bacteria to stop them spreading to other people and objects, which can spread illnesses such as food poisoning, flu or diarrhoea.
It can help stop people picking up infections and spreading them to others.
It can also help stop spreading infections when you're visiting someone in hospital or another healthcare setting.
