What are the symptoms of Norovirus?

Norovirus can be said to be a relatively common acute gastroenteritis virus. It should be noted that this virus is extremely contagious and can be transmitted through oral and hand contact, food, air and other media. Especially in public places, prevention of these viruses should be more cautious. Once infected, patients will experience vomiting and diarrhea, accompanied by fever, muscle aches and other obvious symptoms.

1. Symptoms

1. The main symptoms of infection with this virus are vomiting and diarrhea, and some cases are also accompanied by nausea, abdominal pain, fever and muscle aches. The disease is a self-limiting disease and usually recovers within 2 to 3 days.

2. If parents or teachers find that the child has symptoms such as vomiting and diarrhea, they should send the child to a doctor in time and the doctor should treat the symptoms accordingly. If it is confirmed to be norovirus, the child should stay at home during the illness and avoid crowded places to prevent infection to other people.

2. How to prevent Norovirus?

(1) Pay attention to hand hygiene. Wash your hands thoroughly with soap and water, especially after using the toilet and changing diapers, and before eating, preparing, and handling food.

(2) Pay attention to food hygiene and drink boiled water. Collective units should maintain a clean and sanitary environment, pay special attention to ensuring the safety of drinking water, and not drink raw water; units that use direct drinking water should regularly clean and maintain direct drinking water machines. Fruits and vegetables should be carefully washed before eating, and oysters and other shellfish should be deeply processed before eating.

3. Schools, childcare institutions and other densely populated places should strengthen prevention:

(1) Morning inspections should be strengthened. Ask students if they have any symptoms of vomiting or diarrhea. If a suspected patient is found, isolate and treat him/her immediately;

(2) Strengthen publicity and education on food hygiene. Educate students not to eat raw or cold food or undercooked food, especially prohibit eating raw shellfish and other aquatic products, to prevent the spread of diseases through food and water;

(3) If vomitus from a patient is found on campus, it must be disinfected and disposed of promptly. If there are a large number of cases, the Social Development Bureau or the Centers for Disease Control and Prevention must be notified in a timely manner.
