Influenza A virus: Learn about prevention, protect your health.
Abstract:Influenza A virus is a common influenza virus with high infectivity and mutation ability. This article will introduce the influenza A virus in detail, including its transmission route, infection symptoms, prevention and methods, etc., to help you improve your understanding of influenza A and enhance your self-protection ability.
1. Introduction to influenza A virus.
Influenza A viruses are a type of influenza virus that can be divided into multiple subtypes based on their surface hemagglutinin (H) and neuraminidase (N). So far, 16 isoforms of hemagglutinin (H1 H16) and 9 isoforms of neuraminidase (N1 N9) have been discovered. There is no subtype distinction between influenza B and C viruses. Influenza A virus has frequent genetic mutations, leading to seasonal influenza epidemics and influenza pandemics.
2. Mode of transmission.
Influenza A viruses are mainly transmitted through droplets, such as coughing and sneezing. In addition, it can be infected through direct or indirect contact with items contaminated with the virus. The virus spreads quickly among people, especially in confined and crowded environments.
3. Symptoms of infection.
The symptoms of influenza A virus infection are similar to those of common influenza, mainly including high fever, fatigue, headache, muscle aches and other poisoning symptoms. Respiratory symptoms are relatively mild and usually include cough, runny nose, etc. Severe cases can lead to complications such as pneumonia and acute respiratory distress syndrome, which can be life-threatening.
4. Preventive measures.
1.Vaccination: Influenza A vaccination is an effective means of preventing influenza A and is recommended every autumn.
2.Good personal hygiene Xi: wash hands frequently, wear masks, avoid crowded places, etc., to reduce the risk of virus transmission.
3.Enhance immunity: Maintain adequate sleep, a balanced diet, and moderate exercise to improve your own immunity.
4.Indoor ventilation: Maintain indoor air circulation to reduce the amount of time the virus stays in the air.
5.Follow your doctor's instructions: If someone in your family is infected with influenza A, other members should follow their doctor's advice and take antiviral drugs to prevent it.
Fifth, the method.
The main causes of influenza A virus infection** include the following:
1.Antiviral**: Antiviral drugs, such as oseltamivir, can be used in the early stages of infection to alleviate the disease.
2.Symptomatic**: According to the condition and symptoms, give fever, cough suppressant, muscle pain relief and other symptoms**.
