Be alert! This virus is designed to ＂start＂ children, which can seriously cause shock!

　　Recently, Niu Niu (a pseudonym), a 1-year-old child, developed symptoms of vomiting and diarrhea. On the third day, his symptoms did not improve, but he also had a seizure. His parents rushed him to the hospital. Combined with clinical manifestations and examination results, the doctor diagnosed that Niu Niu was suffering from "acute gastroenteritis with benign convulsion". The convulsion was caused by impaired digestive function, while vomiting and diarrhea were infected with rotavirus.

　　After testing, the child’s stool was positive for rotavirus. According to the doctor, rotavirus is mainly transmitted by fecal mouth, and infants with imperfect gastrointestinal function and low immunity are susceptible groups.

　　"Rotavirus is a common epidemic pathogen in children. It often causes gastrointestinal symptoms, such as vomiting and diarrhea. Severe diarrhea can lead to serious electrolyte imbalance and a symptom of dehydration. Rotavirus is also contagious." Jiang Jie, deputy director of pediatrics at Changsha Central Hospital, said.

　　The doctor reminded that families with infants should pay attention to prevention when entering the high incidence period of rotavirus.

　　What is rotavirus?

　　Rotavirus (RV for short) is the main cause of severe diarrhea in infants and young children. The main route of transmission is fecal-oral route, and it can also be spread through close contact or respiratory tract. Autumn and winter are the peak seasons of epidemic. Rotavirus is divided into eight groups, which are A, B, C, D, E, F, G and H respectively. Among them, group A is the most common one, and 90% of cases are caused by it.

　　Infants and young children are vulnerable to rotavirus because of their immature gastrointestinal tract and weak defense ability. Group A rotavirus is one of the most important causes of severe diarrhea in infants and young children all over the world, and it is also one of the main causes of death among children under 5 years old in developing countries. Almost all children under 5 years old have been infected at least once.

　　What are the characteristics of rotavirus?

　　1. Epidemic season: mainly in autumn and winter, but it can occur in all seasons.

　　2.
How to spread: Rotavirus is mainly transmitted through faecal mouth. There are a lot of rotavirus in the excrement or vomit of children infected with rotavirus. If food, drink and use are contaminated with viral excrement or vomit, such as hands, clothes and utensils, rotavirus will be directly or indirectly transmitted to others.

　　3.
Susceptible population: Rotavirus is a common cause of viral gastroenteritis in children. Therefore, the incidence population is mainly children, and the high incidence age is between 6 months and 3 years old. Infants and young children at this stage lack anti-bacteria and have poor anti-virus ability, so they need to be vigilant.

　　4. Sources of infection: patients (infectious in acute phase and 4-8 days after illness) and asymptomatic virus carriers (infectious without illness).

　　What is the performance of rotavirus?

　　Sick children will vomit at first, and then have different degrees of diarrhea, mostly accompanied by fever. In severe cases, they will have the clinical characteristics of large stool, more water, more times and less urine.

　　Infected children are generally not too serious. Proper rehydration can heal without medicine. However, when diarrhea (vomiting) is serious, it should not be ignored, and medical treatment should be sought in time.

　　Children will go into shock and even die because of severe dehydration, especially babies younger than 1 year old. A small number of babies infected with rotavirus will also be complicated with myocarditis, convulsions and pneumonia, etc., which should also be paid attention to and treated promptly.

　　Note: If the child’s symptoms do not improve within three days of treatment or any of the following symptoms appear, he should also seek medical attention immediately:

　　① The number and quantity of diarrhea increased;

　　② Frequent vomiting;

　　3 obvious thirst;

　　4 can’t eat normally;

　　⑤ fever;

　　⑥ Blood in stool.

　　How to avoid rotavirus infection?

　　Rotavirus enteritis is a self-limiting disease, which usually heals itself in about a week. The general treatment principle is to prevent and correct dehydration, use drugs rationally under the guidance of doctors and actively prevent complications.

　　How to prevent this disease? Pay attention to these five points:

　　1. At present, there is no specific anti-rotavirus drug. Therefore, vaccination against rotavirus is the most effective measure to prevent rotavirus acute gastroenteritis.

　　2. Babies and their caregivers should develop good hygiene habits, especially pay attention to hand hygiene, and do not touch mouth, eyes, nose and food with dirty hands; Don’t let the baby eat his hands, and clean them in time.

　　3. Pay attention to family hygiene, the room is often ventilated, and the baby’s utensils (bottles, bowls, spoons, etc.) need to be cleaned before use, and the clothes, quilts, toys, etc. should be changed frequently.

　　4. Encourage and insist on breastfeeding.

　　5. Items contaminated by rotavirus should be thoroughly disinfected by high temperature, disinfectant or sun exposure.
