Cold is a common disease for people, but many people's understanding of cold is not comprehensive. Let's listen to how experts introduce it.
Cold, generally divided into common cold and influenza, here we first discuss the common cold. Common cold, known as cold in traditional Chinese medicine, is a common respiratory disease caused by a variety of viruses, 30% - 50% of which is caused by a certain serotype of rhinovirus.
Although the common cold often occurs in early winter, it can also occur in any season, such as spring and summer. The pathogenic virus of the common cold in different seasons is not exactly the same. Influenza is an acute respiratory infectious disease caused by influenza virus. The virus is present in the patient's respiratory tract and is transmitted to others through droplets when the patient coughs or sneezes.
Influenza is very infectious. Because the virus is easy to mutate, even people who have had the flu will still be infected when they encounter the next influenza epidemic, so influenza is easy to cause an outbreak. Generally, there are more chances of epidemic in winter and spring, and 20-40% of people may catch influenza every time.
