What Are the Types of Influenza?

Every spring and autumn season, the incidence of influenza is relatively high. For people with weaker resistance, influenza often occurs. Influenza is actually contagious because it is caused by viral infections. Different viruses require different treatment methods. So, do you know what types of influenza are there? Influenza (abbreviated as flu) is an acute respiratory infection caused by the influenza virus, which is also a highly contagious and rapidly spreading disease. It is mainly transmitted through droplets in the air, contact between people, or contact with contaminated objects. Typical clinical symptoms include: sudden high fever, body pain, significant fatigue, and mild respiratory symptoms. Generally, autumn and winter are the high-incidence seasons, and the complications and deaths caused by it are very serious. The disease is caused by the influenza virus and can be divided into three types: A, B, and C. Type A virus often undergoes antigenic variation, is highly contagious, spreads rapidly, and is prone to large-scale epidemics. Type A H1N1 is one of the subtypes of Type A. This disease is self-limiting, but it is easy to develop severe complications such as pneumonia and lead to death in infants, the elderly, and patients with underlying cardiopulmonary diseases. Seasonal influenza has strong transmission ability between humans, and active prevention and control are more important than limited effective treatment measures. The main preventive measures are as follows. 1. Keep indoor air circulating and avoid crowded places during peak periods. 2. Use tissues when coughing or sneezing to avoid droplet transmission. 3. Wash hands thoroughly and frequently to avoid touching the mouth, eyes, and nose with dirty hands. 4. Seek medical attention promptly if influenza-like symptoms occur during the epidemic, reduce contact with others, and try to rest at home. 5. Influenza patients should be isolated for respiratory isolation for one week or until the main symptoms disappear. Patient utensils and secretions should be thoroughly disinfected. 6. Strengthen outdoor physical exercise to improve the body's resistance to disease. 7. Pay attention to adding or subtracting clothes due to the variable autumn and winter climate.
