How Long Is Norovirus Contagious? UK

Norovirus, commonly known as the winter vomiting bug, is a highly contagious virus that can cause severe vomiting and diarrhoea. It's a common illness in the UK, especially during the winter months. Knowing how long the virus is contagious is crucial for preventing its spread and protecting yourself and others.

How Long Can You Spread Norovirus?

You can spread norovirus from the moment you become infected until at least two days after your symptoms have stopped. This means you can be contagious even if you feel completely well.

Here's a breakdown of the infectious period:

• Pre-symptomatic: You can be contagious before you experience any symptoms, typically for around 12 to 48 hours.
• Symptomatic: You're highly contagious while you are experiencing symptoms, which typically last 12 to 60 hours.
• Post-symptomatic: You can still be contagious for up to two days after your symptoms have stopped.

How Norovirus Spreads

Norovirus is spread through contact with an infected person, their vomit or faeces, contaminated surfaces, or contaminated food and water.

Here are some common ways the virus can spread:

• Direct contact: Touching an infected person or their vomit or faeces.
• Indirect contact: Touching contaminated surfaces such as door handles, toys, or phones.
• Food and water: Consuming food or water contaminated by an infected person.
• Airborne transmission: Norovirus can spread through the air in tiny droplets released when an infected person vomits or coughs.

Protecting Yourself and Others

Knowing how long norovirus is contagious helps you take steps to prevent its spread:

• Wash your hands frequently: Wash your hands thoroughly with soap and water, especially after using the toilet, changing diapers, and before eating.
• Clean and disinfect surfaces: Regularly clean and disinfect surfaces that may have come into contact with vomit or faeces.
• Avoid close contact with infected individuals: Stay away from people who are sick with norovirus, especially during the early stages of the illness.
• Wash contaminated laundry separately: Wash clothing and bedding that may have come into contact with vomit or faeces in hot water and bleach.
• Don't prepare food if you are sick: If you have norovirus, avoid preparing food for others to prevent spreading the virus.

When to See a Doctor

While most people recover from norovirus within a few days, it is important to contact your doctor if:

• Your symptoms are severe or prolonged.
• You are concerned about dehydration, especially in children and the elderly.
• You have underlying health conditions.

Takeaway

Norovirus is highly contagious and can spread easily. Understanding its contagious period and taking preventive measures can help you stay healthy and prevent the spread of this common illness.
