Understanding Norovirus (Vomiting Bug), Also Known as the Winter Vomiting Bug: Symptoms, Prevention, and Treatment Options
Norovirus, often called the “winter vomiting bug,” is a very contagious virus that causes sudden vomiting and diarrhoea. It spreads easily in shared spaces like schools, workplaces, or households and is most common during the winter. Knowing how to spot the symptoms, prevent its spread, and care for yourself if you catch it can help protect you and your loved ones.
What Are the Symptoms of Norovirus?
If you have Norovirus, you might notice symptoms 12 to 48 hours after being exposed. Common symptoms include:
• Feeling sick or nauseous.
• Sudden vomiting, sometimes forceful.
• Watery diarrhoea.
• Stomach pain or cramps.
• Feeling tired or achy, sometimes with a mild fever, chills, or headache.
Most people feel better within a few days, but some may continue to have mild symptoms like diarrhoea for a little longer. While it’s usually not serious, dehydration can occur, especially in young children, elderly adults, or anyone with other health problems (NHS, 2023).
How Does Norovirus Spread?
Norovirus spreads incredibly easily. Here’s how it happens:
• Close Contact: Being near someone who has the virus.
• Contaminated Surfaces: Touching surfaces or objects that have the virus on them.
• Food and Drink: Eating or drinking something prepared by someone with the virus.
• Vomiting Particles: Breathing in tiny virus particles during vomiting incidents.
It can survive on surfaces for days, so keeping things clean is very important to stop it from spreading (NHS, 2023).
How Can You Prevent Norovirus?
The best way to avoid Norovirus is through good hygiene. Here are some simple tips:
1. Wash Your Hands
Often Use soap and water to wash your hands thoroughly, especially after using the toilet, changing nappies, or before handling food. Hand sanitiser isn’t as effective against Norovirus.
2. Keep Surfaces Clean
Disinfect surfaces with a bleach-based cleaner, especially in kitchens and bathrooms.
3. Handle Food Safely
Don’t prepare or handle food for others if you feel unwell or for at least 48 hours after your symptoms have stopped.
4. Wash Dirty Clothes and Linens
If clothing or bedding is soiled with vomit or diarrhoea, wash them at a high temperature (60°C or more) and use gloves when handling them.
By following these steps, you can help stop Norovirus from spreading to others.
How Is Norovirus Treated?
There’s no specific medicine for Norovirus, but most people recover at home within a few days. The main focus is on managing symptoms and staying hydrated:
• Drink Plenty of Fluids: Sip water, clear broths, or oral rehydration solutions to replace lost fluids and avoid dehydration.
• Get Rest: Rest is important to help your body recover.
• Eat Simple Foods: When you feel ready to eat, stick to bland foods like rice, bananas, and toast. Avoid alcohol, caffeine, and spicy or fatty foods.
If dehydration is severe (symptoms like dark urine, dry mouth, or dizziness), you should seek medical attention immediately.
When Should You Get Help?
While most people recover quickly, there are times when you might need to see a doctor. Contact a healthcare professional if:
• Your symptoms last more than a few days.
• Vomiting or diarrhoea is severe or continuous.
• You notice signs of dehydration, such as feeling very thirsty, producing little or no urine, or feeling faint.
Conclusion
Norovirus is unpleasant but usually short-lived. By practising good hygiene and avoiding close contact with sick people, you can reduce your chances of catching or spreading the virus. If you do get sick, focus on staying hydrated, resting, and following these simple steps to recover.
