Families 'must stay indoors for 48 hours' as highly contagious virus spreads - UK | 29 Dec 2024 | Norovirus is highly contagious, but there are ways to protect yourself and other family members if someone in your household falls ill. According to the NHS, norovirus can be transmitted through close contact with an infected person, touching contaminated surfaces or objects and then touching your mouth. Food prepared or handled by a sick person can also be a breeding ground for the virus. And alcohol hand gels do not kill the norovirus bacteria. People suffering from the vomiting bug are advised to stay away from work or school until they have been free of any vomiting or diarrhoea for at least two days. It's also recommended that visits to places with potentially vulnerable individuals, such as hospitals or care homes, should be avoided during this time. [Do not comply.]
