A new coronavirus is systematically classified into the coronavirus family in coronaviridae. It is an RNA virus that is easy to replicate and mutate, with an incubation period of up to 12 days. The clinical symptoms of infection with the new coronavirus are fever, fatigue, respiratory symptom (mainly dry cough), gradually breathing difficulties, and (in severe cases) acute respiratory distress syndrome, sepsis shock, incorrigible metabolic acidosis and haemorrhagic and coagulation dysfunction. 

Prevention measures

Is it necessary to wear a mask? How to wear a mask?
Wearing a medical surgical mask can effectively prevent respiratory disease
When wearing a disposable medical mask, you should
fully unfold the folded surface, and completely cover the mouth, nose, and jaw; squeeze the nose clip so that the mask fits perfectly on the face; identify the inside and outside of the mask. The light side is the inside and should be close to the mouth and nose. The dark side should be outward. The end of the metal strip (nose clip) is the upside. Replace disposable masks regularly. Reverse wearing of a mask and wearing each side of a mask in turn are not allowed.

In addition, you are suggested to rinse your throat with light salt water before going to the hospital or other public places, and do it again after going home. Specifically: take a mouthful of light salt water, raise your head to keep the salt water in your throat, open your mouth slightly to let the airflow slowly exhale from your throat and make a "ha" sound. At this time, the salt water will slowly move along with the air flow, and you spit out the water after a few seconds. Then, take another mouthful of water and repeat the steps. Do this for 3 to 5 times. Because the virus or bacteria first lurks in the throat through the nasal cavity, the light salt water can kill it at the first time to achieve the purpose of preventing infection. This method is simple, effective, and easy to implement, and you are advised to insist on it.
