At present, it is the season of high incidence of norovirus infection. While preventing COVID-19 from "resurgence", we should also be alert to norovirus gastroenteritis. The virus that this population is generally susceptible to increases with the opening of primary and secondary schools in the city. Experts from the Beijing Center for Disease Control and Prevention will teach you how to prevent norovirus. The symptoms of adults and children "recruited" are different. Norovirus has strong infectivity and rapid transmission ability. The whole population is generally susceptible, and the immune protection time after infection is short. It is the main pathogen causing acute gastroenteritis epidemic, and often causes transmission in schools, kindergartens, hospitals, nursing homes and other crowded places. People infected with norovirus can cause acute gastroenteritis. Symptoms usually appear 12-48 hours after ingestion of the virus. The most common symptoms are diarrhea and vomiting, followed by nausea, abdominal pain, headache, fever, chills and muscle soreness. Children mainly vomit, and adults mainly diarrhea. Norovirus acute gastroenteritis is a self-limited disease, which is mild and usually lasts for 2-3 days. The prognosis is good, but it does not rule out that some elderly people or children have severe symptoms, and the duration is longer. This kind of "small seafood" should be fully processed. Norovirus is mainly transmitted through feces and mouth. The specific modes of transmission are diverse: ingesting contaminated food and water; Contact with patient excreta or vomitus; Contact with contaminated hands, objects or appliances; Contact with aerosol produced by vomiting can cause norovirus transmission. In addition, most outbreaks caused by foodborne transmission are caused by food contamination by kitchen workers infected with norovirus. However, the experts of the Municipal Center for Disease Control and Prevention in the Institute of Epidemiology specially reminded that bivalves such as oysters can enrich the norovirus in the sea water and become high-risk food. It is difficult to blame the six viruses to develop good dietary hygiene habits. Do not drink raw water, drink boiled water or choose barreled water that is hygienic and qualified. Wash the fruits and melons before eating raw, and oysters and other shellfish must be fully heated and cooked before eating. Keep good hand hygiene. Wash hands with soap and flowing water before meals, after defecation, and before processing food. Disinfection paper towels and hand sanitizers cannot replace hand washing. Patients should avoid close contact with others. The transmission of norovirus is strong. Patients should use their own food utensils and daily necessities, try not to contact with others closely, especially pay attention not to make food, and do not care for the elderly and infants. At the same time, strengthen the disinfection of the family environment to avoid infection to the family. During the illness, the patients were isolated at home until 3 days after the symptoms disappeared. In particular, food processors, nursing workers, kindergartens and other patients engaged in service work should immediately leave their jobs and resume work only after they are tested negative for two consecutive times. Do a good job of disinfection. The environment and articles contaminated by vomitus or feces of patients need to be disinfected with chlorine-containing agents (disinfectants with alcohol as the main component have poor disinfection effect). When cleaning up articles contaminated by vomitus, plastic gloves and masks should be worn to avoid direct contact with pollutants. Food utensils can be sterilized by boiling for 30 minutes. Parents should take personal protection when handling pollutants. Don't worry too much after the illness. Don't worry too much after the illness.
