A recent UK Health Security Agency (UKHSA) report has revealed a 60% increase in norovirus cases over the past two weeks, highlighting a rapid spread of the virus across the UK. As colder weather persists, health experts are urging the public to stay vigilant, as norovirus thrives during the winter months.
Often referred to as the “winter vomiting bug”, norovirus is highly contagious and can spread quickly through communities, workplaces, schools, and healthcare settings.
What Is Norovirus?
Norovirus is a common stomach bug that causes sudden and severe gastrointestinal symptoms. It spreads easily through close contact with infected individuals, contaminated surfaces, and infected food or drink.
Cases tend to spike during winter because:
- The virus can survive longer on surfaces in colder temperatures
- People spend more time indoors in close contact
- Immune systems may be weaker during the colder months
These factors create the perfect environment for infections to spread.
Norovirus Symptoms
Symptoms usually begin suddenly and can be intense. The most common symptoms include:
- Vomiting
- Diarrhoea
Other symptoms may include:
- High temperature
- Headaches
- Stomach cramps
- Muscle or body aches
- Fatigue, which may last longer even after other symptoms improve
Due to the severity of vomiting and diarrhoea, dehydration can be a concern, particularly for young children, older adults, and vulnerable individuals.
Can You Catch Norovirus More Than Once?
NYes, you can catch norovirus multiple times. This is because norovirus is not a single virus, but a group of different strains. Immunity to one strain does not protect you from others.
If you find yourself repeatedly affected, it’s important to:
- Improve hygiene and cleaning routines
- Disinfect commonly touched surfaces
Seek medical advice if symptoms are frequent or severe
How Long Does Norovirus Last?
Although norovirus is extremely unpleasant, the good news is that most people recover within 2 to 3 days with rest and home care. In most cases, medical treatment is not required unless symptoms become severe or dehydration occurs.
How to Prevent Norovirus?
The best way to treat norovirus is to avoid catching it in the first place. Simple daily habits can significantly reduce your risk.
Practise Good Hygiene
- Wash your hands thoroughly with soap and water, especially after using the toilet and before eating
- Regularly disinfect hard surfaces
- Wash clothing and bedding frequently at high temperatures
It’s important to note that hand sanitiser and alcohol wipes do not kill norovirus. Always use antibacterial soap for hands and a bleach-based cleaner for surfaces.
Stay at Home If You’re Ill
If you have norovirus:
- Do not go to work, school, or social events
- Stay at home to prevent spreading the infection
If you live with someone who has norovirus:
- Avoid close contact where possible
- Do not share food, towels, or cutlery
- Ensure surfaces and shared spaces are cleaned regularly
Norovirus remains contagious for 48 hours after symptoms stop, so it’s essential to continue precautions even when someone starts to feel better.
Stay Hydrated

- Do not go to work, school, or social events
- Stay at home to prevent spreading the infection

When to Seek Medical Advice
While norovirus usually clears up on its own, some people may benefit from speaking to a GP for reassurance or advice, particularly if symptoms feel severe or difficult to manage at home.
You may wish to consult a GP if:
- Symptoms persist beyond a few days
- Vomiting or diarrhoea is preventing you from staying hydrated
- You’re experiencing worsening fatigue or weakness
- A child, older adult, or someone with an underlying health condition is affected
At Midland Health, our experienced GPs can offer advice on managing symptoms, staying hydrated, and knowing when further care may be needed. If you’re concerned or would like reassurance, a GP consultation can provide helpful guidance.
