Spring is the season of high incidence of infectious diseases, warm spring flowers, all things recover, the growth and reproduction of various pathogenic bacteria, coupled with climate change, the temperature difference between morning and evening is large, leading to the decline of human resistance, and norovirus is one of the high incidence of infectious diseases in spring.
One: What is norovirus?
Norovirus often causes acute gastroenteritis and is a common cause of food poisoning.
The virus has a short incubation period, rapid mutation, strong environmental resistance, a variety of transmission routes and other characteristics, so it is easy to cause transmission between people, all people are generally susceptible to the virus.
Two: what are the symptoms after infection?
The incubation period for norovirus infection is usually 24-48 hours, with a minimum of 12 hours and a maximum of 72 hours.
Norovirus gastroenteritis is usually mild. The most common symptoms are vomiting and diarrhoea, followed by nausea, abdominal pain, headache, fever, chills and muscle aches.
Symptoms of norovirus infection vary between adults and children, with vomiting predominating in children and diarrhea more prevalent in adults.
The virus generally has an acute onset and is self-limited, with most patients recovering in 2-3 days after onset.
But for infants and the elderly, especially those with underlying medical conditions, norovirus gastroenteritis can cause more severe symptoms such as dehydration.
Three: What are the ways to be susceptible to norovirus?
Eating or drinking food or water contaminated with the virus;
Contact with vomit or faeces of a patient;
Contact with contaminated articles;
The virus is transmitted by a spray produced during vomiting.
Four: A treatment for norovirus?
If the symptoms are mild, there are treatments you can take:
1, a small amount of water or rice soup many times, let the stomach and stomach get a rest.
- Don’t eat foods that can easily cause abdominal distension, such as milk and soybean milk.
3, in case of dehydration, pay attention to hydration, oral rehydration if necessary.
Seek medical attention if the following symptoms occur:
1, repeated fever, high fever does not retreat.
- Frequent vomiting and inability to eat.
- The stool is mucinous or pus, and the smell is smelly.
4, abdominal pain is obvious, difficult to relieve after rest.
- Poor mental state, dry skin and lips, sunken eye socket or fontanelle, and significantly reduced urine volume.
Five: How to prevent norovirus infection?
- Maintain good hand hygiene.
Wash your hands properly and keep them clean, especially before handling food or eating and after going to the toilet. Follow the seven-step method before eating and after using the toilet.
- Maintain good food hygiene.
Wash fruits and vegetables carefully and cook food properly, especially if you eat shellfish and seafood that are at high risk of getting norovirus.
3, do a good job of disinfection.
Environments and objects contaminated by vomit or feces of patients need to be disinfected with chlorine-containing disinfectants.
When cleaning items contaminated by vomit, wear plastic gloves and masks to avoid direct contact with contaminants.
- If you have gastrointestinal symptoms such as fever, vomiting or diarrhoea, you should stay away from work or school and seek medical advice.
Be careful not to handle food or care for children, the elderly or people with weakened immune systems.
