The enemy of winter health — how can we prevent it?

Norovirus, one of the most common causes of winter food poisoning,

is extremely contagious, and one infected person can quickly spread it to many others.

Let’s learn more about norovirus, a leading cause of winter gastroenteritis, and prevent it effectively.

Norovirus is spread through contaminated food or water, or through contact with an infected person.

Symptoms appear about 1 to 2 days after infection, and the main symptoms include the following:

Severe vomiting

Diarrhea

Abdominal pain

Mild fever

These symptoms usually improve within 2 to 3 days,

but they can cause severe dehydration in older adults and young children, so extra caution is needed.

How is norovirus transmitted?

Ingesting contaminated food or water

You can become infected by eating food contaminated with the virus during the cooking process.

Contact with an infected person

It can also spread when you shake hands with, or use the same items as, a person infected with the virus.

Contact with virus-contaminated surfaces

The risk of infection is high if you touch an object handled by an infected person and then bring your hand to your mouth.

Prevention methods

Because there is no treatment or vaccine for norovirus, prevention is the best measure.

Wash your hands thoroughly

After going out, before meals, and after using the restroom, be sure to wash your hands with soap for at least 30 seconds.

Cook food thoroughly

In particular, shellfish such as oysters and clams should be cooked thoroughly to an internal temperature of at least 85°C for more than 1 minute.

Maintain cleanliness

Regularly disinfect food preparation tools and surfaces.

Avoid contact with infected people

If an infected person is present, isolate them and thoroughly disinfect the items they used and the surrounding environment.

Keep up fluid intake

If infection symptoms appear, you should drink plenty of water and sports drinks to prevent dehydration.
