China's Ministry of Health has ordered health organizations across the country to strengthen its prevention and control of the norovirus infection, commonly known as "stomach flu". The capital city, Beijing is on high alert to the Norwalk Virus, which is one of the original forms of norovirus.

Health experts say the rate of infection is about average for this time of year in China. However, there is still a likely chance of the virus spreading after recent outbreaks in Japan, Europe and the United States.

Norovirus is one of the most common gastrointestinal viruses affecting humans and is highly contagious. Symptoms include nausea, diarrhea, vomiting and abdominal cramps.

Since last July, outbreaks of stomach flu have hit Japan, Singapore and Italy as well as in South China's Guangdong Province.

Beijing is never complacent. The local health authority has warned the public to be aware of food safety, especially when eating raw seafood.

Symptoms usually appear within 9 to 96 hours of infection.

Wu Jiang, official Beijing disease control and prevention, said, "Many patients who get the virus usually find the major symptoms are nausea, vomiting, which are not so severe. This kind of stomach flu usually passes after 48 hours."

Winter often brings with it many gastrointestinal cases, especially in children. Doctors say the Norwalk Virus is just one that can cause these symptoms and parents of those with severe symptoms should take their children to hospital.

Doctor, said, "Segregation is necessary if children get infected. Patients need to see a doctor for diagnosis. Drinking plenty of water is important. If symptoms are severe, they will need an intravenous injection."

The main ways of contracting the virus is from eating seafood that has not been cooked properly and poor hygiene standards. The health ministry requires hospitals to report abnormal increases in cases quickly.

Despite the health ministry's warning on eating uncooked seafood, some restaurants in Beijing seem unaffected. Raw seafood is still widely available.

Waiter, said, "About 200 customers eat sea food daily."

When asked about how the Norovirus' infection could affect their business, they expressed cautiousness.

Waiter, said, "We have imposed more restrictions when replenish our stock."

Experts say all restaurants should be on high alert. They should implement strict disciplines during the cooking process, such as separating raw and cooked food, and carry out continuous disinfection of kitchen equipment.

If chefs or waiting staff show signs of infectious symptoms, they should go to the hospital immediately. Consumers should wash fruit carefully and cook seafood thoroughly.
