"A respiratory tract infection above the Omikon strain, often occurs with air pads and bronchitis, which causes cough. At the same time, the virus causes the breathing tract mucosa destruction. The immune cells gather here to participate in the battle.And sputum discharge the throat, trachea, and bronchial secretions out of the body, and clean up the battlefield. "Niu Hongtao said.

Cough may continue after heating fever, and generally recover within two weeks of onset."However, as long as the inflammation of the airway continues, the cough may last for 8 weeks after infection." Niu Hongtao told the Science and Technology Daily reporter.
According to Niu Hongtao, cough is divided into dryness and wetness. Virus infections are mostly the former and have no sputum, but some patients will also have cough and phlegm or sputum is not easy to cough, resulting in sustainable cough.
"Cough is a protection mechanism of the human body. Cough after infection is a situation that many respiratory virus infections will occur, so you don’t have to be too nervous."

If the cough affects life, sleep, etc., it is recommended to go to the hospital respiratory department or online consultation in time to obtain individualized treatment suggestions. At the same time, avoid smokingKeep away from pollution and irritating smell, "Niu Hongtao said.
There are also some people who have sputum and it is difficult to cough.In this regard, Niu Hongtao suggested taking phlegm drugs."If the color of sputum is turned from white to yellow, and the amount is increasing, or even pus, it may be that the respiratory defense ability is reduced due to virus infection, and bacterial infections are merged. It is recommended to take antibiotics for 3 days to 5 days."
