What is Norovirus?

Norovirus is a viral infection that primarily affects the stomach and intestines, causing inflammation known as gastroenteritis. It is infamous for its ability to spread rapidly, especially in crowded places like schools, hospitals, and cruise ships.

Key Symptoms of Norovirus

If you come into contact with norovirus, symptoms usually appear within 12 to 48 hours. Common signs include:

• Nausea and vomiting
• Diarrhea
• Stomach cramps
• Fever or chills
• Headaches and muscle aches
• Fatigue

These symptoms typically last one to three days, but the virus can still spread even after you feel better.

How Does Norovirus Spread?

Norovirus spreads through contaminated food, water, or surfaces. It can also pass from person to person through direct contact. Key sources include:

• Eating or drinking contaminated food or beverages
• Touching contaminated surfaces and then touching your mouth
• Being in close contact with an infected person

Even a tiny amount of the virus is enough to cause illness, making it one of the most contagious stomach bugs.

Preventing Norovirus Infections

While there’s no vaccine for norovirus, there are simple steps you can take to reduce the risk of infection:

1. Wash Your Hands: Use soap and water for at least 20 seconds, especially before eating or preparing food.
2. Clean Surfaces: Disinfect high-touch areas, especially if someone in your household is sick.
3. Handle Food Safely: Cook food thoroughly and avoid cross-contamination.
4. Stay Home When Sick: If you’re unwell, avoid preparing food for others to prevent spreading the virus.

When to Seek Medical Help

Most cases of norovirus resolve on their own, but dehydration can be a serious concern, particularly for young children, the elderly, and those with weakened immune systems. Seek medical attention if you or a loved one experience:

• Severe dehydration (dry mouth, dizziness, decreased urination)
• Symptoms lasting longer than three days
• Bloody stools or high fever

What Experts Are Saying

Health officials are urging the public to remain vigilant. The Centers for Disease Control and Prevention (CDC) emphasize that proper hygiene is the best defense against norovirus. Experts also recommend staying hydrated and resting during recovery.
