Part of humanity can get the disease all year round, especially in winter and spring, where climate change is relatively large, due to sudden changes in the human body’s inability to adapt to natural conditions. It has now been confirmed that the majority of the flu is caused by the virus. The cold, over-fatigue, frailty, malnutrition, etc. seen in our daily life are the triggers of a cold. Cold virus is not specific to certain viruses, but a large group of viruses including more than a dozen viruses. Because various types of viruses may infect each other but can not mutually immunize each other, they cause colds repeatedly throughout the year. Although the disease is not a serious disease, but it can be the source of all diseases, often secondary to other diseases, should cause everyone enough attention.
