When a patient sneezes, a sneeze contains thousands of influenza viruses, some of which enter the human body through the mouth or nose, and then these viruses begin to attack the cells in the body. When they constantly swim to the nucleus of the cell central system and reach the vicinity of the nucleus, the influenza virus will open its inner membrane and release the virus genes inside, which will enter the nucleus and immediately force the cells to replicate and produce new virus genes.
The growth rate of influenza virus is amazing, 12 hours can increase by 100 times. Although these influenza viruses want to reinfect as soon as possible before the human immune system reacts, when the immune system realizes it, these viruses will eventually be swallowed up and destroyed. Winter is the outbreak season of influenza. If you don't pay attention to keep warm, your immunity will decline, and some viruses floating in the air are likely to take the opportunity to invade your cells. Therefore, in the cold winter, remember to wear more clothes, drink more hot water, keep indoor ventilation, and protect your body from viruses to the greatest extent.
Self-limited disease means that the disease will not cause obvious clinical symptoms, and after a certain period of development, the disease will be controlled through body regulation and gradually recovered. Or although it causes some symptoms, it does not last long, and will not cause permanent or excessive harm to the body after the symptoms of the disease disappear. Common in viral or bacterial infections, such as the common cold. Even if the common cold is not treated, the related symptoms will disappear in a week or so, which is the so-called self-limiting disease.
