Norovirus UK: How Long Does It Last?

Norovirus, commonly known as the winter vomiting bug, is a highly contagious virus that causes vomiting and diarrhoea. It is prevalent in the UK, particularly during the winter months. While most people recover quickly, understanding how long norovirus lasts can help you manage the illness and prevent its spread.

How Long Does Norovirus Last?

The symptoms of norovirus typically appear 12 to 48 hours after exposure, and they usually last 12 to 60 hours. In some cases, however, they can persist for up to 3 days.

Here's a breakdown:

• Nausea and vomiting: This is usually the first symptom and can last for 1 to 2 days.
• Diarrhoea: Diarrhoea can start at the same time as vomiting or a few hours later. It can last for 1 to 2 days.
• Other symptoms: Headache, muscle aches, fever, and chills may also occur. These symptoms are typically milder and shorter-lived than vomiting and diarrhoea.

Who is at risk for a longer duration?

While most people recover within a few days, some individuals may experience longer-lasting symptoms. These include:

• Young children
• Older adults
• People with weakened immune systems

It's crucial to seek medical advice if your symptoms persist or worsen.

How to Prevent the Spread of Norovirus

Norovirus spreads easily through contact with an infected person or contaminated surfaces. Here are some essential steps to prevent its spread:

• Wash your hands frequently: Wash your hands thoroughly with soap and water, especially after using the toilet, changing nappies, and before eating.
• Disinfect surfaces: Regularly clean and disinfect surfaces, especially in high-touch areas like door handles, taps, and toilets.
• Avoid close contact: Stay away from people who are ill with norovirus.
• Wash contaminated laundry: Wash contaminated laundry thoroughly and separately, using hot water and detergent.

When to See a Doctor

While norovirus is generally a mild illness, it's important to seek medical attention if you experience the following:

• Severe dehydration: Signs include excessive thirst, dry mouth, sunken eyes, and dark urine.
• Persistent vomiting: If vomiting continues for more than 2 days.
• High fever: A fever above 38°C (100.4°F).
• Blood in your vomit or stools:
• Severe abdominal pain:

Conclusion

Norovirus is a common and highly contagious illness. Most people recover within a few days, but some may experience longer-lasting symptoms. By understanding how long norovirus lasts and following preventive measures, you can minimize the risk of infection and spread. Remember to seek medical advice if your symptoms worsen or persist.
