Recently, the National Influenza Center released

usually

Influenza is more high in winter and spring

Why is there an anti -seasonal peak this year?

How can we effectively prevent it?

The reporter interviewed relevant experts

Fluid is not only popular in winter and spring

Influenza, that is, the abbreviation of influenza virus, is caused by influenza virus, with strong infectious respiratory diseases. In people's general impressions, the flu virus seems to be "scared", generally only spread in winter and spring, but this year it is "activity" in summer, which makes many people feel puzzled.

In this regard, Guo Wei, deputy chief physician of the respiratory department of Tianjin Children's Hospital, said in an interview with reporters that in fact, summer flu is not available this year. In 1918, the Spanish influenza began to start from May, and at that time, it also affected Guangzhou, Shanghai, Wenzhou and other places in my country.

"The reason why there are many summer influenza in southern my country this year, mainly related to the low temperature of these places." For example, in May of previous years, the temperature in Fuzhou, Xiamen and other places can reach about 33 degrees Celsius. The minimum temperature is only 13 degrees Celsius. In addition, due to the continuous rainfall in the south, the temperature also lowered. Such temperature conditions can prolong the time when influenza virus maintains contagious, and also creates a suitable environment for its large -scale communication.

The flow of A is more likely to cause a large -scale popularity than the B flow

The main influenza is A (H3N2) subtype influenza virus. It belongs to the type A influenza (hereinafter referred to as A flow) virus, which has the characteristics of strong infectious and fast transmission speed. Guo Wei said.

Not only is the transmission speed of A virus, but also the symptoms of their infected people are usually heavier. In addition to the general symptoms of upper respiratory tract infection (runny nose, sore throat, cough), the infected person will also have a high fever of more than 39 degrees Celsius, accompanied by discomfort such as tremor, headache and muscle pain.

"The statistical results show that the chance of occurring in A flow is three times that of the B flow. The reason why the flow of A can cause large -scale spread is mainly related to its" good change '. "Chen Chunqi explained that the flow of A virus can be further divided into various types of various types. The theoretically as many as 198 species.

In contrast, the variation speed of the B virus is relatively slow, and its variation speed is only 10%to 20%of A. Many people who have suffered from the B will produce antibody immunity. Therefore, the B virus usually has only local and small -scale transmission, which rarely causes a large range of transmission.

Vaccination is the most effective prevention method

Even if the influenza virus is confirmed, the public does not have to panic and anxiety. "A small number of patients need to be hospitalized because of complications, and most infected people can recover within a week." Guo Wei said that after the infection of the virus, pay attention to avoid cross -infection of family members. Life in life, do not contact other members of the family, etc.

For prevention, Guo Wei said that inoculation of influenza vaccines is the most effective prevention method, which can significantly reduce the risk of influenza and severe complications in the vaccinator. Influenza vaccines currently approved by my country have three -valent vaccine (mainly used for vaccination in June and above), three -price drug reduction vaccine (mainly used for vaccination of people 3 to 17 years old), four -valent vaccine ( Mainly used for vaccination for people over 3 years old). The three -valent flu vaccine mainly prevent H1N1, H3N2 and BV influenza; in addition to preventing the above three types of influenza, the quasal influenza vaccine can also prevent BY influenza.

Guo Wei also reminded that he washing his hands is one of the simplest and most important measures to prevent influenza. After contacting public goods and sneezing, you should wash your hands in time. In addition, it is necessary to ventilate and maintain family environment. In the period of high influenza during the high incidence of influenza, the flu is likely as possible to go to a place where people are dense and closed.

Oascifer's prescription medicine

Do not buy and take yourself

With the high incidence of summer influenza in the south, netizens in many places recently said that Anti -virus drugs, Anti -virus drugs, which are known as "influenza medicine," are out of stock. In some places, "one medicine is difficult to find".

In this regard, Guo Wei, deputy chief physician of the Department of Respiratory Department of Tianjin Children's Hospital, introduced that Osdowei belongs to neuropine enzyme inhibitors. By inhibiting the activity of neurophanase activity of type A and type B virus, inhibit the virus Releasing the cells, reducing the further spread of type A and B virus in the human body. It can alleviate the symptoms of influenza and shorten the course of influenza.

However, Guo Wei said, "Osaswati is a prescription medicine. You need to have a prescription prescribed by a doctor to buy. You cannot buy it yourself."

Guo Wei emphasized that from a medical perspective, taking Ostewiri does have the effect of preventing flu, but this is not a regular prevention method. Usually doctors only recommend that they have intimate contact with influenza patients and are prone to severe people to take medicine prevention. The best way to prevent flu is the flu vaccination.
