"The school has recently experienced gastrointestinal discomfort symptoms. The sampled specimens have been tested by the laboratory of the Centers for Disease Control and Prevention and have been confirmed as 'norovirus type 2'. Considering that the virus is highly contagious and has a certain incubation period, in order to avoid cross-infection, the school decided to adjust a day off and suspend collective activities such as class classes next week."
It is reported that several primary and kindergartens in Ningbo have suspended classes in the past half month because students have been infected with norovirus . Recently, disease control departments in various places have also received many reports of norovirus clustered epidemics, with most of them occurring in kindergartens and primary and secondary schools.
The Center for Disease Control and Prevention has also issued a health warning
reminding citizens to pay attention to norovirus infection
Health
warning
In April, norovirus infection is still in the high incidence period, and its incubation period is mostly 1 to 2 days. The main symptoms are nausea, vomiting, fever, abdominal pain and diarrhea, which often cause collective outbreaks in communities, schools, restaurants, hospitals, nurseries, etc. Norovirus is mainly transmitted through the digestive tract and is extremely contagious. Eating or drinking food or beverages contaminated by norovirus, contacting objects contaminated by norovirus, and directly contacting infected people may be infected. Shellfish is an important vector for food-borne norovirus infection. Frozen or refrigerated shellfish can help the virus prolong its survival time.
Understanding Norovirus
Norovirus, also known as norovirus , nowalk virus , is a virus that causes non-bacterial acute gastroenteritis. Norovirus causes infectious diarrhea of and is highly contagious. It is a self-limiting disease. Generally, special treatment is not required, and there is currently no special medicine.
Infection Symptoms 1
Norovirus sounds a bit terrifying, but it is actually a common virus, not a new type of virus.
From October to March of the following year, is the peak season for the outbreak of norovirus. The main infection targets of are the elderly and children with poor resistance. After infection, people will experience acute gastrointestinal inflammation such as vomiting and diarrhea within 48 hours. is more common because of vomiting. Therefore, it is also called "winter vomiting disease".
transmission route 2
Norovirus is highly infectious and can be transmitted through feces-oral routes. It can be transmitted through contaminated water sources, food, items, air, etc. It often causes collective outbreaks in communities, schools, restaurants, hospitals, nurseries, nursing homes and the army. The main causes of infection are:
1. Eat or drink food, water or beverages contaminated by norovirus;
2. contacts objects or surfaces contaminated by norovirus, and then contacts the mouth with hands;
3. directly contacts infected people, such as taking care of patients, eating with patients, or using the same tableware, etc.
extremely infectious 3
This is a highly infectious virus that only requires 10-100 viral particles to cause disease. You should know that hundreds of millions of virus particles can be excreted by vomiting in one go. The virus spreads in the air through aerosols, causing a clustered outbreak.
Provincial disease control experts introduced that norovirus is currently in an active period in the country. Including our province, there have been norovirus infectious diarrhea in schools in , including in our province.
If someone at home is infected with norovirus , vomits or has diarrhea, remember to disinfect contaminated furniture, floors and clothes in time according to the correct method - first sprinkle a chlorine-containing disinfectant such as "84". It is best to cover the vomit with disinfectant powder for 30 minutes before cleaning it.
antibiotics are ineffective 4
There is no specific drug after infection with norovirus. After infection with norovirus, we will have diarrhea and vomiting. Sometimes we will take antibiotics on our own. This is the wrong method. antibiotics are ineffective against Norovirus. , which will only cause the abuse of antibiotics.
It is a self-healing disease, just like a cold. Just symptomatic treatment is needed. If a fever decreases, diarrhea stops diarrhea.It is worth noting that within 3 days after the symptoms disappear, the virus carried on the body still has strong transmission power. Therefore, it is best not to go to the crowded places 3 days after is cured, so as not to cause the virus to spread again.
No vaccine 5
Like influenza, norovirus is very easy to mutate. Even if you have been infected with this virus, there is still no exemption. The next time the virus hits in a new form, your immune system is still a piece of paper in front of it. The bad news is that there is no vaccine for it yet. There are currently several small companies in the United States that are developing vaccines, and it will take some time to go public.
