The UK Health Security Agency (UKHSA) has issued a stark public health warning as a highly contagious stomach bug spreads across the country. The agency is urging anyone who falls ill with norovirus to stay at home for a full 48 hours after their symptoms have stopped to prevent further transmission.
What is Norovirus and How Does It Spread?
Norovirus, often called the winter vomiting bug, is not flu or Covid-19 but is an extremely contagious virus causing vomiting and diarrhoea. The UKHSA alert, posted on social media platform X, emphasises that the virus spreads easily through multiple routes.
According to NHS guidance, it can be transmitted via close contact with an infected person, touching contaminated surfaces or objects and then touching your mouth, or consuming food handled by someone who is unwell. Crucially, alcohol-based hand gels do not kill norovirus, making thorough handwashing with soap and warm water essential.
Official Guidance to Curb the Spread
The agency's clear advice is designed to protect workplaces, schools, and vulnerable settings. Do not return to work or school until 48 hours after symptoms cease, as you can still be contagious during this period. Furthermore, the UKHSA strongly advises against visiting hospitals or care homes within this timeframe to avoid triggering serious outbreaks among those most at risk.
Regular handwashing with soap and warm water is the primary defence recommended to stop catching the virus and to avoid passing it on if you are already sick.
Symptoms, Home Care, and When to Seek Help
For most people, norovirus is an unpleasant but short-lived illness. Recovery typically occurs within two to three days with rest and by drinking plenty of fluids to stave off dehydration.
However, the NHS cautions that certain symptoms require immediate medical attention. You should seek urgent help if vomit resembles ground coffee, contains blood, or appears green or yellow-green. These can be signs of a more serious complication requiring professional care.
With the warning issued on Christmas Eve, the UKHSA hopes these measures will help limit the impact of the virus during the festive period, protecting families and health services alike.
