Unlike Corona Viral Disease is Norovirus Common in China?


Unlike Corona, New Norovirus is very common in China, with symptoms similar to gastrointestinal colds

Recently, a message of “a new type of virus- Norovirus enters a high incidence period” has recently spread among parents and  friends, causing a lot of concern. The reporter learned that the so-called "new virus-Norovirus" is actually very common. The viral infectious diarrhea caused by it is distributed every year.

Southern is prone to winter

11In November 2014, the Guangdong Provincial Center for Disease Control and Prevention issued a risk alert: the seasonal peak of viral infectious diarrhea was killed and will continue until March of this year. Norovirus infectious diarrhea is one of them.

Prion diarrhea, also known as viral gastroenteritis, is a group of acute intestinal infectious diseases caused by a variety of viruses. Most of the clinical symptoms are acute, with symptoms such as nausea, vomiting, abdominal pain, diarrhea, drainage or loose stools, and fever and general malaise. Although these viruses spread faster, they have a lower impact and a shorter duration. The mortality rate is low.

According to He Waner, rotavirus is the most common form of viral diarrhea. Pathogens are mainly transmitted through the digestive tract. The susceptible population is mainly children under 2 years old.

The peak of the disease is in autumn and winter. The most typical symptoms are vomiting and pulling, most of which are accompanied by fever. Two to three days later, they start to pull watery stool.

The course of diarrhea caused by rotavirus infection is short, usually 3 to 5 days.

Another more common virus is adenovirus, which is more common in young children. Then there is the more frequent Norovirus, also known as Norovirus, which was discovered in the United States in 1968. In 1995, China reported the first case of Norovirus infection, which was considered an "old" virus.
Norovirus likes cold and heat, and winter is the season when norovirus and other viral infectious diarrhea are high.

People are generally susceptible to norovirus. Because of their low resistance and immunity, children over 2 years of age are more susceptible to infection. Similar to adenovirus, norovirus infection also has symptoms such as nausea, vomiting, diarrhea, and abdominal pain.

Prion-infected diarrhea is mostly a self-limiting disease

At the same time, Dr. He also said that although rotavirus, adenovirus, norovirus and other viral infectious diarrhea are more contagious, they are mainly distributed in groups, and they occur in concentrated places such as kindergartens and schools, but they are self-limited.

In general, no special treatment is needed for sexually transmitted diseases, mainly by rehydration and diet conditioning to control symptoms and other treatments. Parents should not take it lightly. They must do a good job in preventing dehydration, but they should not be too panic.

The chief physician of the Department of Pediatrics of a Maternal and Child Health Hospital said that in daily life, when a child develops diarrhea, some parents often blindly take antibiotics to their children without understanding the cause (the parents said "Anti-inflammatory drugs"), they feel that "you must use antibiotics if you have an infection." 

When you still have diarrhea for two or three days, you come to the hospital for treatment. In fact, this method is unscientific. Antibiotics can inhibit or kill pathogenic microorganisms, but it is not a "universal medicine". In the absence of bacterial infections, rush to use antibiotics. 

When the child actually develops a bacterial infectious disease, those real pathogens actually have Drug resistance makes treatment more difficult. In children, rotavirus enteritis is caused by a viral infection.

Antibiotics not only have no effect on it, but if abused, they will aggravate the intestinal flora imbalance, which will prolong the repair time of the damaged intestinal mucosa and prolong diarrhea. Parents who use antibiotics for rotavirus enteritis are not uncommon.

Therefore, Xie Danyu suggested that when children have diarrhea, parents should not rush to use antibiotics immediately. What parents need to do is to pay attention to the characteristics of their diarrhea and take them to the hospital in time so that they can be diagnosed as early as possible through the pathogenic examination. After a kind of diarrhea, a corresponding treatment plan is formulated to achieve symptomatic treatment without delaying the illness.

Do good sanitation

Prion diarrhea is mainly transmitted by feces and mouth, and can also be transmitted by droplets from diarrhea or vomit from infected people and inhaled patients. Therefore, the most effective way to deal with viral diarrhea is to prevent it, and "gate the entrance."

The Guangdong Provincial Health and Family Planning Commission recommends that people first develop healthy living habits such as washing hands frequently, not drinking raw water, and separating raw and cooked foods to avoid cross-contamination; secondly, strictly prevent illness from entering the mouth. Norovirus is commonly found in shellfish, vegetables and fruits, such as fresh vegetables and fruits and vegetables that are irrigated and washed with water contaminated by Norovirus, which can attach the virus to the surface. 

Shellfish are cultured in contaminated water. Filtered food gradually accumulates noroviruses. Therefore, before eating fruits, you must wash and peel; shellfish and seafood must be cooked thoroughly before consumption.

In addition, among the currently common viral diarrhea, only rotavirus has a corresponding vaccine. Xie Danyu said that for some frail infants or infants with poor gastrointestinal conditions, especially fragile premature infants, or children with congenital diseases (such as congenital heart disease), they can also be used in the epidemic season. Rotavirus vaccines are given orally to reduce the risk of developing the disease.

If your child has symptoms of vomiting or diarrhea, parents are advised not to force them to school to avoid spreading more children and causing collective illness, and they should seek medical treatment in a timely manner. Symptoms of norovirus infection are mainly abdominal pain, diarrhea, and vomiting, but they usually only last for two or three days. 

While cooperating with your doctor, keep a light diet, but do not fast. "Drink plenty of water and rest. The condition will be obvious. He Waner's special emphasis on drinking more water. Whether it is prevention before illness or recovery after illness, drinking water can help.

Drinking more water can promote toxin excretion in the body, which is beneficial to the functioning of the gastrointestinal tract. There is also cold weather to avoid cold food, so as not to increase the burden on the gastrointestinal tract.

Hunchun is approaching and gastrointestinal colds are common

It is worth noting that the clinical manifestations of norovirus infection are similar to those of a cold, so many patients have not been treated or diagnosed as "gastrointestinal cold". What kind of disease is "gastrointestinal cold"? Dr. Yu Tao, Deputy Chief Physician, Deputy Director of Gastroenterology, Sun Yat-sen Memorial Hospital, Sun Yat-sen University, said that the disease has also recently occurred, but the outpatients are mainly adults who eat and drink. 

Before and after the holidays, patients related to gastrointestinal clinics, emergency departments, acute gastroenteritis, and gastrointestinal colds increase significantly.

The patient vomits while having a runny nose

"Gastrointestinal cold" has both gastrointestinal reaction and cold symptoms from the name. Yu Tao introduced that most of the disease is caused by a type of coxsackie virus, which is caused by oral or respiratory infections, and sometimes accompanied by mixed infection with other bacteria. 

From the clinical point of view, most patients will have the same gastrointestinal symptoms as acute gastroenteritis, and may also be accompanied by the typical symptoms of colds, such as: sore throat, nasal congestion, runny nose, cough, sputum, fever and general soreness. This is why some patients come to the clinic and vomit while having a sore throat and coughing.

"Patients with acute gastroenteritis usually have a history of unclean diet before onset." Yu Tao said that the most common reason for this type of patients is eating cold dishes, barbecues, hot pots, leftovers, etc. These foods are susceptible to salmonella. Contamination with genus or Staphylococcus aureus causes acute inflammation of the gastrointestinal tract, and fever may occur in severe cases, but no respiratory symptoms similar to colds.

Wu Yutao showed that gastrointestinal symptoms are common to gastrointestinal colds and acute gastroenteritis, and are the most prominent manifestations. This broad category of symptoms is caused by inflammation, edema, or irritation of the gastrointestinal tract, and mainly includes nausea, vomiting, abdominal pain, diarrhea, and dehydration such as dry mouth, yellow urine, and dizziness.
Apart from Corona New Norovirus is common in China


"Anti-inflammatory drugs" are not effective against viruses

Wu Yutao reminded that patients with gastrointestinal colds and acute gastroenteritis mostly go to the outpatient department and emergency department of gastroenterology. Examination of blood routinely showing an increase in white blood cells and neutrophils and an increase in white blood cells found in stool can further verify the diagnosis of this disease. Severe patients can also find electrolyte imbalances during blood tests.

Some minor gastrointestinal colds and acute gastroenteritis can heal within a week, and some milder acute gastroenteritis can be relieved even within a day. However, gastrointestinal symptoms are obvious, and patients with severe fever and dehydration should still seek medical treatment as soon as possible. We often say "anti-inflammatory drugs" refer to antibiotics used to kill bacteria. They are not effective against viruses. Therefore, they are less commonly used in gastrointestinal colds caused by viral infections. The main symptomatic treatments are antidiarrheal and fluid supplement.

Acute gastroenteritis, especially the more severe patients, should be treated with antibiotics and the necessary symptomatic treatment mentioned above. One more thing to note is the problem with intravenous treatment. In fact, most patients, as long as they can drink water, can eat porridge and noodles, dehydration performance is not obvious, and intravenous fluid supplements are not necessarily required. Clinically there are some oral rehydration compound preparations. Replenishing electrolytes and water not only saves the pain of injections, but also saves medical costs, which is more convenient and economical.

Yu Tao finally suggested that you should drink plenty of water, eat more fresh fruits and vegetables and light and easily digestible foods, ventilate your residence, avoid crowded and closed public places, avoid unclean diets, and prevent the above diseases. of. The Spring Festival is approaching. I hope that when the Chinese people celebrate the Spring Festival, they must also take good care of their small intestines and stomachs, in case the "small intestines and stomachs" are in trouble!

What are the symptoms of a gastrointestinal cold? 

Symptoms of digestive tract are the most prominent manifestations of gastrointestinal colds. The specific manifestations are as follows:

1. Nausea and vomiting: Nausea is caused by stomach irritation. Serious irritation will cause strong contraction of stomach muscles and vomiting;

2. Abdominal pain: It is a common reason for patients to see a doctor. Gastritis can cause upper abdominal pain. Spasticity caused by inflammation of the small intestine will cause patients with colic around the navel. Frequent infestation, anal bloating and left colic often cause colic. Prompt colorectal inflammation;

3. Diarrhea: It is commonly known as "diarrhea", which is mainly caused by intestinal irritation and secretes a large amount of mucus. At the same time, intestinal edema affects the absorption of food and water, causing excessive water in the intestinal cavity, and intestinal peristalsis is enhanced. The stool that is finally discharged becomes sloppy or watery. Patients generally have abdominal distension before defecation, which is also caused by too much water in the intestine;

4. Performance of dehydration: due to loss of appetite, vomiting and diarrhea, a large amount of water is lost, resulting in dehydration. This is a serious condition and requires vigilance and attention. Patients with dry mouth, dry skin, dizziness, fatigue, deeper and yellower urine, reduced urine output, such patients should seek medical treatment without delay.
