Norovirus UK: Symptoms & How Contagious It Is

Norovirus, commonly known as the winter vomiting bug, is a highly contagious virus that can cause severe vomiting and diarrhoea. It's a common ailment in the UK, particularly during the winter months. Understanding how the virus spreads, recognizing its symptoms, and taking preventive measures are crucial to protect yourself and others.

Norovirus Symptoms

The most common symptoms of norovirus infection include:

• Sudden onset of vomiting: This is often the first symptom and can be very intense.
• Diarrhoea: This can range from mild to severe and may be watery or bloody.
• Nausea: Feeling sick to your stomach is common before or after vomiting.
• Stomach cramps: These can be painful and debilitating.
• Headache: This is a less common symptom, but can still occur.
• Fever: A low-grade fever is possible, but not as common as other symptoms.
• Fatigue: Feeling tired and weak is typical after an infection.

These symptoms usually appear within 12 to 48 hours after exposure to the virus and can last for one to three days. In most cases, recovery is complete within a week.

How Contagious is Norovirus?

Norovirus is incredibly contagious. It can spread easily through:

• Direct contact with an infected person: This includes touching their vomit or faeces.
• Indirect contact with contaminated surfaces: The virus can live on surfaces for a long time and be picked up by touching objects like door handles, toys, or utensils.
• Breathing in contaminated air: Tiny droplets containing the virus can spread through the air when an infected person vomits or has diarrhoea.
• Consuming contaminated food or water: Norovirus can contaminate food and water, leading to infection when consumed.

Even small amounts of the virus can cause infection. This is why it can spread so quickly, especially in crowded places like schools, hospitals, and care homes.

How to Prevent Norovirus

While there is no specific cure for norovirus, there are ways to prevent infection and spread:

• Wash your hands frequently and thoroughly: Use soap and water for at least 20 seconds, especially after using the toilet, changing nappies, and before preparing food.
• Clean and disinfect surfaces: Use a bleach-based disinfectant on surfaces that may have come into contact with the virus.
• Avoid close contact with sick people: Stay away from anyone experiencing vomiting or diarrhoea.
• Wash contaminated clothing and bedding separately: Wash them in hot water with detergent.
• Stay hydrated: Drink plenty of fluids to prevent dehydration, especially when experiencing vomiting and diarrhoea.
• Prepare food safely: Wash fruits and vegetables thoroughly and cook food to the correct temperature.
• Practice good hygiene: Cover your mouth and nose when coughing or sneezing, and dispose of tissues properly.

Conclusion

Norovirus is a common and highly contagious virus, but it's not usually serious. Taking simple precautions and following the advice above can help prevent infection and protect yourself and others. If you experience norovirus symptoms, stay home and rest to prevent further spread. Seek medical advice if you have concerns about your symptoms or experience severe dehydration.
