Health authorities in the United Kingdom have issued a stark warning that people can contract a common and unpleasant winter illness more than once during the current season. The UK Health Security Agency (UKHSA) has stressed that even if you have already suffered from norovirus, you remain vulnerable to catching it again.
Understanding the Norovirus Threat
Norovirus, often dubbed the 'winter vomiting bug', is a stomach infection known for its rapid onset and highly contagious nature. Primary symptoms include forceful vomiting and diarrhoea, which can lead to dehydration. The NHS notes that while the illness typically resolves within two to three days, the symptoms during this period can be severe and debilitating.
Other signs of infection may encompass a high temperature, aching limbs, stomach cramps, and headaches. The health service emphasises that the most crucial step in recovery is to consume plenty of fluids to counter the risk of dehydration caused by fluid loss.
Critical Advice to Curb Transmission
To protect the wider community, especially vulnerable individuals in healthcare settings, strict isolation rules are in place. The NHS advises that anyone experiencing symptoms must avoid attending school, work, hospitals, or care homes until 48 hours after their symptoms have fully stopped.
In a social media post on platform X, the UKHSA reinforced this message, stating: "If you have recently knocked norovirus out of your system, the last thing you want is to catch it again." An accompanying infographic clearly explained that prior infection does not grant immunity for the rest of the season.
How to Prevent Infection and Spread
Norovirus spreads easily through contaminated surfaces, food, water, and close contact with an infected person. Key preventative measures recommended by the NHS include:
- Washing hands frequently with soap and warm water, as alcohol gels are ineffective against norovirus.
- Thoroughly cleaning contaminated surfaces like toilet handles, taps, and door knobs.
- Washing any clothing or bedding soiled with vomit or faeces separately on a hot cycle (60°C).
- Avoiding preparing food for others while symptomatic and for 48 hours afterwards.
By adhering to this guidance, the public can help limit the impact of this disruptive seasonal bug and protect those most at risk.
