Nova virus infection in children: comprehensive analysis and response strategies
Introduction
In the area of children ‘ s health, the disease of the virus is an issue that cannot be ignored. As children are not yet fully mature in their own immune systems, they are more vulnerable to the virus, which causes a series of symptoms of discomfort that affect their lives and development. Knowledge about children ‘ s positive HIV infections, including the characteristics of the virus, the symptoms of infection, the means of transmission, diagnostic methods, preventive measures and response measures, are essential for safeguarding children ‘ s health.
II. Characteristics of the virus
(i) Structure and type of virus
It’s a single-chain RNA virus without a membrane. It’s a corset-like. Its viral particles are spherical, about 27 – 40 nanometres in diameter. It’s like a tiny, complex little monster with a unique structure in the microworld. The virus has multiple genomes, of which GIG, GII and GIV can infect humans, and GII is the most common type of infection among children. These different genomes determine some of the characteristics of the virus and its pathogenicity to the human body.
(ii) Environmental stability
The virus is very stable in the environment, like a resilient “survival”. The body of water, the surface of the object, etc. can survive for a longer period of time. For example, in low-temperature environments, it can better maintain activity. Moreover, it has some resistance to heat, acid and commonly used disinfectants. Ordinary clean-up methods may not be able to effectively remove them and remain sustainable for 30 minutes at 60°C and can survive for three hours in pH2.7 environments, making them vulnerable to residues in the environment in which children live and increasing the risk of exposure and infection.
III. Symptoms of HIV infection in children
(i) Gastrointestinal symptoms
Gastrointestinal symptoms tend to be prominent when children become infected with the virus. First of all, vomiting, which is probably one of the symptoms that most bothers parents. Children may suddenly start vomiting without warning, and vomiting is more intense and sometimes sprayed. Such vomiting can be frequent, seriously affecting the food and physical state of the child. At the same time, diarrhoea is a common symptom, and children ‘ s poop can become watery or thin, with a number of times or even dozens of times a day. Frequent vomiting and diarrhoea can lead to rapid dehydration and electrolyte disorders in children, which may be more serious than adults because of their relatively weak physical reserves.
(ii) All-body symptoms
In addition to gastrointestinal symptoms, the child has a series of overall symptoms. Heating is common and can rise to low, moderate or even high levels of heat, which can make children uncomfortable and restless. In addition, there are symptoms of headaches, muscular acidity and inactivity. Young children may not be able to express an accurate feeling of headaches or muscular sourness, but may display acts such as crying, reluctance to move. These systemic symptoms further weaken the physical and mental state of the children and affect their normal play and rest.
(iii) Special performance and pathological characteristics
Among children, there may also be some particular manifestations of the virus. For example, because of frequent vomiting and diarrhea, children may suffer from hunger and lack interest in the food they normally like. Some babies may cry because of abdominal discomfort. Moreover, children are generally less likely to be infected with the virus, mostly in 1-3 days, but during this period their bodies will experience greater testing. After rehabilitation, the virus may still be present in excreta for some time and still be contagious and require parental attention.
IV. Children ‘ s ways of transmitting the virus
(i) Manure – oral transmission
This is one of the main routes for children to become infected with the virus. Children may be exposed to contaminated environments in their daily lives, such as the ground in public places, toys, etc. If these sites are contaminated with the faeces containing the virus, the children touch their mouths, eat, etc. without washing their hands after playing, the virus enters through the mouth. For example, in the toilets in kindergartens, children are vulnerable to infection when they use them if they are not cleaned and virus residues are found around the toilets.
(ii) Food dissemination
Children prefer to eat a variety of foods, especially cold, uncooked foods, which increases the risk of food transmission of viruses. For example, children may become infected when they eat extra meals in kindergartens with fruits, salads, etc. contaminated with the virus. In addition, home-made foods that are contaminated during processing can also be a source of transmission of the virus. For example, parents do not wash their hands before they process their food, and when they carry their own Noma virus, they may transmit the virus to food, thereby infecting children.
(iii) Exposure dissemination
Close contact between children is an important way of transmitting the virus. In places where children gather, such as kindergartens, schools, children play together, share toys, embrace each other, etc., which can lead to the spread of the virus. If a child is infected with the Noura virus, he may have the virus on his hands and on his body and when he is in contact with other children, the virus is transmitted to the other child. Moreover, children often touch the surrounding objects and their bodies with their hands, such as eyes, noses, mouths, etc., which also creates conditions for the virus to enter the body.
(iv) Aerosol dissemination
In some special cases, e.g., aerosols produced when children vomit may contain a Norovirus. Other children may be infected when they inhale these aerosols, which contain viruses. In relatively closed spaces such as classrooms and dormitories in kindergartens, children are at risk of infection if they vomit and are not treated in a timely manner. Such transmission channels increase the likelihood of rapid transmission of the virus among children.
V. Diagnosis of HIV infection in children
(i) Clinical diagnosis
When diagnosing a child with a virus, the doctor first makes a diagnosis based on clinical symptoms. If children experience typical acute gastrointestinal conditions such as vomiting, diarrhoeal diseases, fever, especially in the case of the norovirus epidemic season or in the case of exposure history, there is a high level of suspicion that it is notovirus infection. However, diagnosis on the basis of symptoms may be confused with other gastrointestinal diseases and further laboratory tests are required for diagnosis.
1. Nucleic acid testing
Nucleic acid testing is an important method of diagnosing a child ‘ s Novovirus infection. By collecting samples of children’s faeces, vomiting or anal swabs, the RNA was tested using the PCR technique. This method, which is highly sensitive, allows for the accurate detection of viruses and enables the identification of their genomes and genotypes, is of great assistance in understanding their origin and prevalence. This can be done in better-off hospitals or CDCs. 2. Antigen detection
Antigen testing is relatively simple and fast and can be used in primary health-care facilities. It determines whether the child is infected by testing the antigen of the virus in the sample. However, antigen testing may not be as sensitive as nucleic acid testing, and false negative results may occur in samples with lower viral loads, so other detection methods need to be combined when necessary. 3. Seroscopy
The serology tests are mainly for specific antibodies in children’s serums. After the infection of the virus, a corresponding antibody is produced in the child, which can be diagnosed by testing changes in IgM and IgG antibody levels. However, serological tests are generally used for retrospective diagnostics or epidemiological studies and have limited value for early diagnosis of acute infections, as antibody creation takes some time.
VI. Prevention of HIV infection in children
1. Handwashing practices
The development of good hand-washing habits for children is key to preventing the transmission of the virus. Parents and teachers are required to teach children to wash their hands carefully with soap and running water for a period of not less than 20 seconds after meals, after contact with public goods, after outdoor activities, etc. Children can learn to wash their hands in the right way through their children ‘ s songs, games, etc., such as rubbing their hands on their backs, sewping their fingers, etc., so that they become conscious behaviour in their daily lives. 2. Dietary hygiene guidance
Children are taught to be healthy and not to eat raw and cold food, such as unwashed fruit, raw water, uncooked meat and seafood. In kindergartens and families, safe and healthy food is provided for children. For younger children, parents should be careful to feed and keep their food safe. For example, when eating fruit for a child, the virus should be thoroughly cleaned and removed from the surface. Avoiding exposure to sources of infection
Children are taught to avoid exposure to people with vomiting and diarrhoea. Reduction in the number of children reaching densely populated and poorly ventilated public places during the Norte virus epidemic. If a kid gets sick around, keep a distance. At the same time, parents and teachers take care to observe the environment around children and to identify possible sources of infection in a timely manner.
1. Clean household environment
The family is the main place of life for children, and it is important to maintain a clean and healthy family environment. The ground, furniture, toys, etc. are regularly cleaned and disinfected, especially where children are frequently exposed. Chlorinated disinfectants can be used to wipe, but care is taken to avoid harm to children by using appropriate concentrations in accordance with the instructions. Good indoor ventilation is maintained, with regular daily windows open and fresh air entering the room to reduce the presence of the virus. 2. Environmental management in schools and kindergartens
In schools and kindergartens, environmental health management needs to be strengthened. Every day, classrooms, dormitories, canteens, toilets, etc. are cleaned and disinfected, and public toys, tables and chairs, etc. are regularly disinfected. Establish a sound health management system, such as the establishment of a person responsible for hygiene and cleaning, training of cleaners and ensuring the quality of disinfection. Following vomiting or diarrhoea in children, specialized treatment of contaminated areas is conducted in a timely manner to prevent transmission of the virus.
1. Food security
School and kindergarten canteens are required to comply strictly with food hygiene standards and to ensure the safety of food procurement, storage, processing and supply. The procurement of fresh, virus-free food products requires rigorous testing of vulnerable foods such as meat and seafood. Food is stored in a manner that is sensitive to temperature and humidity control and prevents food deterioration and contamination. During the process, the food must be cooked and cooked to avoid cross-contamination of raw and cooked food. 2. Drinking water sanitation
Drinking water for children is guaranteed and disinfected water is provided. In kindergartens and schools, drinking water equipment such as drinking water machines are regularly cleaned and disinfected to ensure safe drinking water. For bottled water, care should be taken to check its origin and quality and to avoid the consumption of contaminated water by children.
VII. Children ‘ s response to the virus
1. Symptoms observation and initial treatment
Parents and teachers closely observe the symptoms of children and take timely measures if they are found to have such symptoms as vomiting, diarrhoea and fever. For light vomiting and diarrhoea, children can be given first rest and a small number of oral rehydration salts to prevent dehydration. If the symptoms are serious, such as continuous vomiting, unheated fever, mental infirmity, etc., medical attention is required in a timely manner. At the same time, information on symptoms, vomiting and the frequency of diarrhoea in children should be recorded for medical diagnosis. 2. Segregation and psychological peace
When children are found to be infected with the virus, they should be isolated in a timely manner, avoiding contact with other children and preventing the transmission of the virus. During the isolation period, the parents are accompanied by the child and are given psychological peace. For younger children, fear may arise from physical discomfort, and parents need to alleviate their fear through gentle language, embraces, etc. Teachers are also concerned about the psychological state of other children in kindergartens or schools, so as to avoid panic caused by the illness of their classmates.
(ii) Medical treatment and care
In hospitals, doctors treat children with symptoms. For children with severe vomiting and diarrhoea, water and electrolytics are replenished by intravenous or oral rehydration to maintain the water-salt balance of the body. For children with fever, appropriate deheating drugs are used depending on the temperature. At the same time, changes in the condition of children are closely observed to prevent complications. 2. Care points
Care should be taken to keep children clean when caring for infected children. Replacement of clothing and sheets contaminated with vomiting or excrement in a timely manner, and the use of warm water to wipe children ‘ s bodies and keep their skin clean. In terms of diet, depending on the child ‘ s recovery, the amount of diet is gradually increased, starting with fresh, digestible foods such as rice soup, noodles, etc., so as not to overburden the gastrointestinal tract.
1. Epidemic reporting and monitoring
Children in schools, kindergartens, etc. should report cases of HIV infection in a timely manner to the local health sector and the CDC. At the same time, there is a need to establish an internal epidemic monitoring mechanism to follow closely the health status of other children and to detect potential cases in a timely manner. The health sector and CDC investigate and analyse reported outbreaks, understand the spread of the virus and trends in the epidemic, and provide a basis for prevention and control measures. Public health emergency response
Public health emergency response is initiated in the wake of the Novartis outbreak. Control of the source of the infection, such as disinfection and isolation of classes, dormitories, etc. of sick children. Strengthening health monitoring of other children, conducting health education activities and educating parents and children about the prevention of the virus. At the same time, health resources should be coordinated to ensure that sick children receive timely treatment. During the epidemic, the teaching and activities of schools and kindergartens were adapted to the situation to reduce the concentration of people and prevent further spread of the epidemic.
Conclusions
Children ‘ s no-virus infection is a public health issue involving children ‘ s health, families, schools and society. Understanding the characteristics, symptoms, transmission pathways, diagnostic methods, preventive measures and coping strategies of the virus is essential to protect children from the virus. Through the joint efforts of parents, teachers and all sectors of society to strengthen health education for children, to maintain environmental and food hygiene and to respond to the epidemic in a timely manner, we can effectively reduce the incidence and harm of HIV-related infections among children and ensure their healthy development.
