Norovirus: Symptoms, Complications, and Prevention Tips

Norovirus, often referred to as “the stomach flu,” is a highly contagious virus responsible for most cases of gastroenteritis worldwide. Unlike the seasonal flu, Norovirus primarily affects the stomach and intestines, causing severe vomiting and diarrhoea. It spreads rapidly, especially in close-contact settings like schools, nursing homes, and cruise ships, making it a major public health concern. While the symptoms can be distressing, understanding Norovirus symptoms, complications, and prevention methods is crucial for managing its impact.

What Causes Norovirus?

The primary cause of Norovirus infections is exposure to contaminated food, water, or surfaces. This virus spreads easily through:

• Consuming food or beverages handled by an infected person.
• Touching contaminated surfaces and then touching your mouth.
• Close contact with an infected individual.

Given its highly contagious nature, even small amounts of the virus can cause illness. Outbreaks are common in places with shared spaces, such as hospitals, schools, and restaurants. The virus’s ability to survive on surfaces for days underscores the importance of stringent hygiene practices.

Common Symptoms of Norovirus

Norovirus symptoms typically appear 12 to 48 hours after exposure and include:

• Severe nausea
• Vomiting
• Watery diarrhoea
• Stomach cramps
• Fatigue and muscle aches

Symptoms usually last one to three days but can persist longer in vulnerable individuals. While the illness is unpleasant, most people recover without medical treatment. However, dehydration can occur quickly due to vomiting and diarrhoea, especially in young children and older adults.

Potential Complications of Norovirus

Although Norovirus infections are generally self-limiting, complications can arise, particularly in high-risk groups such as infants, the elderly, and those with weakened immune systems. The most common complication is dehydration, marked by:

• Dry mouth and throat
• Dizziness or lightheadedness
• Reduced urine output

In severe cases, dehydration may require hospitalisation for intravenous fluids. For those with preexisting health conditions, the virus can exacerbate underlying issues, underscoring the importance of early symptom management and hydration.

How to Prevent Norovirus Infections

Preventing Norovirus requires diligent hygiene and safe food-handling practices. Key prevention tips include:

1. Wash Hands Frequently: Use soap and water for at least 20 seconds, especially after using the restroom or before eating.
2. Disinfect Surfaces: Clean commonly touched surfaces with a disinfectant containing bleach to eliminate the virus.
3. Avoid Contaminated Foods and Water: Consume only properly cooked and stored food. Avoid raw shellfish, as they can carry Norovirus.
4. Isolate Infected Individuals: If someone in your household is infected, minimise contact and ensure they use separate utensils and towels.

These steps significantly reduce the likelihood of contracting Norovirus.

What to Do If You Get Norovirus

If you suspect you have Norovirus, follow these steps to manage the illness at home:

• Stay Hydrated: Drink plenty of fluids like water, oral rehydration solutions, or clear broths to replace lost electrolytes.
• Rest: Allow your body to recover by minimising physical activity.
• Avoid Solid Foods Initially: Start with bland foods like crackers or toast once vomiting subsides.

Seek medical attention if dehydration symptoms worsen or if vomiting and diarrhoea persist beyond a few days. While there is no specific Norovirus treatment, managing symptoms effectively can prevent complications.
