When it comes to norovirus, many people may still be somewhat unfamiliar with this term. Norovirus is a virus that causes acute gastroenteritis. It is similar to rotavirus, which can make people vomit and diarrhea. People infected with norovirus will have symptoms of abdominal pain and vomiting, and a few people will also have symptoms of fever, runny nose and cough.
Children's resistance is weak, so children are more likely to be infected with norovirus. Normally, norovirus comes from contaminated water and food. If you eat these foods by mistake, you will have corresponding symptoms.
The large-scale diagnosis of norovirus by students is likely to be related to the food safety problems in restaurants on or off campus, so Baiyun District CDC immediately checked the food safety problems in schools, but the results were surprising. This result also points to the food safety problem of off-campus restaurants.
Most of the confirmed students recalled what they had done before, many of which included eating on campus and some students eating off campus.
It is worth noting that Norovirus is contagious, and students infected with Norovirus are likely to continue to infect others. Therefore, according to the survey results, if there is really no problem with food safety on campus, then maybe some students were infected with norovirus while eating in off-campus restaurants and passed it on to other students.
Food safety and water source safety are very important to human body. Only by working hard to solve these problems can we ensure human security.
