Do not forget to prevent flu!

Recently, the children of our relatives came to me because of the fever. At first, the children only had fever and sore throat, but as the child developed a child cough, sneezing, and a high fever, parents began to fear whether the child would be a new crown. , But there is no epidemic in the city, so parents come to ask me what to do?

I asked if there were similar symptoms around the children recently? According to children's mother's memories, there are several students in the next class of children's kindergartens that have a cold, which may be transmitted when playing together. I asked my parents to take the child to send a popular kidney as nuclear acid. Sure enough, the child was diagnosed with flu.

Starting from the raging epidemic of the new crown, the flu virus seems to be unrealistic. After all, everyone needs to maintain a social distance, and the children also bring a mask, but this year may change. This year The Lord's influenza virus is fierce.

The latest monitoring data released by the China Influenza Center shows that in the 23rd week of 2022 (June 6, 2022-June 12, 2022), the positive rate of influenza virus detection in the southern province continued Compared with (ILI%) 5.8%, higher than the level of the previous week (5.1%), and higher than the same period of 2019-2021 (4.4%, 3.0%, and 4.3%) [1].

Coincidentally, the latest data of the World Health Organization (WHO) global influenza monitoring and response system also shows that since 2022, the incidence of influenza in the north and south hemisphere has rebounded significantly. It became the top priority.

How do we recognize whether children have influenza?

How can ordinary parents identify flu, and what kind of symptoms should start to doubt that children may have flu?

Let's take a brief understanding of flu. The influenza is a infectious disease caused by influenza virus.

Symptoms of flu can be mild or severe. The most common symptoms are high fever, runny nose, sore throat, muscle soreness, headache, cough and fatigue [2]. Influenza patients and hidden infections are the main sources of influenza. They are mainly transmitted through the droplets of their respiratory secretions. They can also be transmitted directly or indirectly through mucous membranes and other mucosa of the mouth, nasal cavity, and eyes. In the annual influenza epidemic seasons, children's influenza incidence is 20%to 30%, and the annual infection rate of some high -end season can be as high as about 50%[3].

Symptoms of influenza are similar to ordinary colds and new crown pneumonia. Although many symptoms are the same, there are still some differences:

The difference between influenza and ordinary colds

Ordinary colds can basically occur at any time throughout the year, and influenza often has obvious "seasonal limits", which is generally good in summer and winter.

The symptoms of ordinary colds are relatively mild, generally not fever or only low (<38 ° C). The main symptoms are sneezing, nasal congestion, runny nose, sore throat, and cough. Although many symptoms are the same as it, the flu is often accompanied by high fever (39 ° C to 40 ° C), and the symptoms of influenza will be significantly serious than normal colds, sore muscle, fatigue, and loss of appetite during the flu.

The difference between influenza and new crown pneumonia

There are many similarities in the symptoms of these two diseases, and they will have fever, cough, shortness of breath or dyspnea, fatigue, sore sore, runny nose or nasal congestion, muscle pain, headache, nausea or vomiting, but the new crown may be accompanied by a sense of smell. The loss of taste, while influenza patients will not have this symptom.

Generally, the influenza disease is relatively short. Most of the symptoms of influenza children with non-complications are alleviated at 3-7D, but cough and physical recovery often take 1-2 weeks. New crown pneumonia may grow in influenza, especially patients with severe illnesses.

Through research, a disease was also found to be on the disease with children with a new crown-children's multi-system inflammatory syndrome (MIS-C). The disease occurs in children under the age of five. The main symptoms are systemic inflammation and organ failure. It will also be accompanied by conjunctivitis, rash, lymph nodes, etc. [4].

As ordinary parents, if the child has a fever and a systemic symptoms, the best way is to go to a popular kidney consultation, conduct new crown testing and influenza testing to confirm the disease.

Influen

Can we ignore it?

The answer is no! Especially in children under 5 years of age, children in this age are more risk of severe and hospitalized after infection of influenza viruses. It is estimated that about tens of thousands of children under the world died of influenza -related respiratory diseases every year. [5]

Influenza can cause a lot of complications. The most common is pneumonia. Pneumonia is more common in infants and young children under the age of 2. Generally, 2-3 days after the flu. , Difficult to breathe. Influenza pneumonia can be combined with different pathogen infections such as other viruses and mycoplasma, and combined with bacterial infection is one of the main causes of severe diseases and death.

Influenza can also cause other respiratory complications such as pharyngitis, bronchitis, bronchitis, etc. If children have bronchial asthma, influenza may increase bronchial asthma.

In addition to affecting the respiratory system, influenza can also cause complications of nervous system (such as meningitis, spinalitis, etc.), heart damage, otitis media, etc. Figure 3 Influenza virus (derive from the Internet)

How to treat influenza?

Influenza can cause so many complications, so it is very important to regulate correct treatment. We generally evaluate the general status of children (sleep, diet, urination), and then choose suitable treatment based on the severity of the disease. Children with severe influenza start to fight anti -influenza virus drug treatment as soon as possible within 48H. Early treatment can obtain better clinical results, but this does not mean that it is meaningless for more than 48h treatment. It is helpful to alleviate clinical symptoms [6].

The anti -flu virus drugs currently approved by my country are mainly neurophanine inhibitors, including Oaswavir, Paramine, and Zamil. According to the central influenza center, the influenza monitoring data in the 23rd of the influenza monitoring of 100 influenza strains is shown that all type B influenza strains are sensitive to neuropine inhibitors.

In addition to drug treatment, other symptomatic treatment is also very important. Fever causes a large amount of water in the body, timely replenish sufficient water, avoid water shortage and cause shock, and it is also important to provide children with a quiet and comfortable rest environment.

Prevention is always the first!

Vaccination of flu vaccines every year is the most effective means to prevent flu, which can significantly reduce the risk of influenza and severe complications.

Maintaining good personal hygiene habits is an important means to prevent respiratory infectious diseases such as influenza. To tell children, when you go home, you must wash your hands and wash your face. Before meals, you need to wash your hands before and after the toilet. If there are more than one child in the family, one of the children suffer from flu, then they must take a good job of isolation to avoid cross -infection.

Conclusion:

This year's influenza virus infection has an upward trend in the world. Many cities in the southern region of my country have issued influenza warnings. We must be alert to infection with new crowns and influenza. Children should inoculate influenza vaccines as soon as possible to obtain immune protection as soon as possible.
