Hello fellow veterans, I believe many people do not know much about the influenza virus. Therefore, today I will share with you about the influenza virus and what influenza A is. I hope this knowledge can help you solve some of your confusions. Let’s take a look below!

1. What is influenza A
When H1N1 broke out, it also posed a great threat to human life and health just like this year\’s COVID-19 epidemic. But with the vaccination and the weakening of toxicity, influenza A has become a common cold.
2. Virus envelope What is the influenza virus envelope composed of
Some viruses (such as influenza viruses and other animal viruses) have an envelope (outer envelope) wrapped around the protein capsid – the viral envelope. This envelope is mainly derived from the host cell membrane (phospholipid layer) and membrane proteins), but also contains some of the virus\’s own glycoproteins. The main function of the viral envelope is to help the virus enter host cells. First, the glycoprotein on the envelope surface recognizes and binds to the host surface receptor, then the viral envelope binds to the host cell membrane, and finally the viral capsid and viral genome enter the host to complete the infection process.
3. What kind of virus is the influenza in late September this year
1 .The influenza in late September this year was caused by influenza A virus.
2. Influenza viruses are divided into types A, B and C. Influenza A viruses are divided into two subtypes: A H1N1 and A H3N2. type.
Based on epidemiological surveillance data and isolation and identification of virus strainsIt is determined that the influenza in late September this year was mainly caused by influenza A H3N2 virus.
Influenza A H3N2 virus is relatively common in the population and has high contagiousness and pathogenicity.
3. The variability of influenza viruses is high, and the subtypes and strains of influenza viruses may change every year.
Therefore, the development and vaccination of influenza vaccines is one of the important measures to prevent influenza.
In addition, maintaining good personal hygiene habits, such as washing hands frequently, avoiding contact with virus sources, using tissues or elbows to cover coughs and sneezes, etc., can also Effectively reduce the spread of influenza.
4. What is the virus in the flu movie
\”Flu\” \” is a science fiction thriller directed by Mila Kunis. It tells the story of a plague called the \”Max Miller\” virus that swept the world, causing a sudden increase in the death toll and many governments announcing that they were unable to control it. The virus in the movie is a composite virus with a completely new genetic composition. It is composed of three viruses: SV40 virus, influenza virus A and influenza virus B. These three viruses themselves all exist in animals, but they have been manipulated by scientists. Fusion together creates a powerful super virus that possesses the infectivity and pathogenicity of three viruses at the same time, posing a great threat to mankind.
5. Why do influenza viruses continue to mutate
What are the effects of influenza viruses on After different drugs produce antibodies, they will continue to change themselves in order to survive, leading to constant mutations. Changes in weather are most likely to cause viral colds. In winter, you should pay attention to keeping warm, drink more water, exercise more, and improve your immunity.
