Introduction: Within 48 hours after infection with Norovirus, patients will experience symptoms of acute gastroenteritis such as vomiting, diarrhea, and more frequent vomiting. In the winter, it is also a period of high prevalence of norovirus outbreaks, so Norovirus infectious diarrhea is also called "winter vomiting." Things passed On December 1, an outbreak of suspected norovirus infection occurred in Luofang kindergarten in Luohu District, Shenzhen. As of 14:00 on December 1, a total of 44 cases were found in the park, involving 42 children and 2 teachers. The main symptoms were abdominal pain, vomiting, and diarrhea.

Norwalk virus is a prototype strain of Norovirus in the human calicivirus family. Norovirus was first isolated from the feces of an acute diarrhoea patient outbreak in the city of Nova in the United States in 1968. The first was called the small round structure virus, later called the Norwalk-like virus, until the eighth International Nominating Committee of the Virus in August 2002 approved the name Norovirus. Within 48 hours after infection with Norovirus, the patient will experience symptoms of acute gastroenteritis such as vomiting and diarrhea, with more vomiting symptoms. In the winter, it is also a period of high prevalence of norovirus outbreaks, so Norovirus infectious diarrhea is also called "winter vomiting." This is a highly infective virus that requires only 10 - 100 virus particles to cause disease. You know, one vomit can expel hundreds of millions of virus particles. The virus spreads through the air in the air, causing an outbreak of clustered outbreaks. If someone at home is infected with norovirus, vomiting or diarrhea, remember to disinfect the contaminated furniture, floors, and clothing in a timely manner in the right way. Disinfection method: First sprinkle with a chlorine-based disinfectant such as “84â€. The vomitus should be covered with disinfectant powder for 30 minutes and then cleaned. At this time, medical alcohol is not effective. Family precautions 1. Pay attention to personal hygiene, wash your hands frequently, and develop good habits before and after meals. 2. Do not eat cold foods and undercooked foods and try to minimize dining out. 3. Try to avoid activities in densely populated places and eliminate the channels of transmission. 4. In order to prevent Norovirus infection, oysters and other shellfish seafood should be consumed after deep processing, try not to eat raw. 5. If there is a Norovirus infection in the family, the family member should wear a mask when handling vomitus, and use chlorine bleach to disinfect the surface contaminated by vomit or feces of the patient in time to prevent the disease from entering the mouth. Xiaomi said: At present, there is no vaccine for Norovirus listed. At present, there are several small companies in the United States in the development of vaccines, the market will take some time.
