Health officials are reporting a seasonal increase in norovirus cases across the United Kingdom as winter approaches. The highly contagious virus, often called the winter vomiting bug, is currently showing its highest infection rates in children under four years old.
Understanding the Norovirus Threat
Norovirus activity has remained within expected levels in recent weeks, according to Amy Douglas, Lead Epidemiologist at the UK Health Security Agency (UKHSA). However, she emphasizes the importance of taking simple steps to prevent the virus from spreading as temperatures drop.
The virus is known for its rapid onset, with an incubation period of just 12 to 48 hours. Early symptoms typically include sudden vomiting and diarrhoea, often followed by a high temperature, headache, and general aches and pains.
Protecting Vulnerable Groups and Preventing Spread
Norovirus can be particularly serious due to the risk of dehydration, especially for vulnerable groups including young children, older people, and those who are immunocompromised.
"At the moment, the highest rate of cases is in children," stated Ms Douglas. "If your child has any symptoms, please keep them off school or nursery until 48 hours after their symptoms stop."
She also advised that adults who become unwell should not go to work or prepare food for others until 48 hours after their symptoms have ended. Additionally, people should avoid visiting hospitals and care homes to prevent spreading the infection to vulnerable residents.
Effective Hygiene Practices
Contrary to popular belief, alcohol-based hand gels are not effective against norovirus. The UKHSA stresses that washing hands with soap and warm water is the crucial first line of defence.
If someone in your household contracts the virus, health experts recommend:
- Using disposable gloves when handling contaminated items
- Cleaning surfaces with bleach-based disinfectants
- Washing contaminated clothing or bed linens at 60°C
Norovirus spreads easily through close contact with infected individuals, touching contaminated surfaces, or eating food handled by someone with the virus. By following these guidelines, you can help prevent the spread of this unpleasant illness in your community this winter.
