The UK Health Security Agency (UKHSA) has issued a fresh alert concerning norovirus, the highly contagious stomach bug often dubbed the 'winter vomiting bug'. While current case numbers are reported to be within typical seasonal expectations, health officials are urging the public to remain vigilant.
What are the symptoms of norovirus?
Norovirus is an incredibly unpleasant illness that strikes suddenly. The most common signs include violent and sudden vomiting, as well as watery diarrhoea. According to official NHS guidance, these primary symptoms are often accompanied by a range of others.
Patients may also experience a high temperature, headaches, aching limbs and stomach cramps. The good news is that for most healthy individuals, the illness is short-lived, typically running its course and clearing up in about two days.
How does the winter vomiting bug spread?
Norovirus is notoriously contagious and spreads with alarming ease. The primary mode of transmission is through contact with an infected person or by touching surfaces contaminated with the virus.
The colder months create the perfect environment for its spread, as people spend more time congregating indoors. While most people make a full recovery, the virus poses a greater risk to specific groups. The very young, the elderly, and those with weakened immune systems are particularly susceptible to dehydration, which is the most common complication.
Essential steps for prevention and recovery
If you or a family member falls ill with norovirus, the illness can usually be managed at home. The single most important action is to ensure you drink plenty of fluids to stave off dehydration.
To prevent the virus from spreading through your household and community, follow this crucial advice:
- Wash your hands frequently with soap and warm water.
- Immediately wash any contaminated clothing or bedding at 60 degrees Celsius.
- Disinfect high-touch surfaces daily, including toilet seats, flush handles, taps, and door handles.
- Avoid preparing food for others if you are unwell.
- Do not share towels, flannels, cutlery, or utensils.
- Stay away from swimming pools for at least 48 hours after your symptoms have completely stopped.
It is also strongly recommended that you stay at home and avoid work or school for 48 hours after your symptoms have cleared to prevent passing the virus on to others.
