“Masks are useful. Some people think that wearing a mask is to prevent you from infecting others with the disease, but actually in China, the concept is the opposite. Wearing a mask is to prevent others from infecting you. This may be a conceptual difference, but it’s also a fact. ” Zhong Nanshan stressed that most of the virus is not actually free in the air, but exists in droplets, spread by coughing and other ways. In the west, they can also protect themselves by wearing masks.
He pointed out that China is facing the challenge of local transmission caused by imported cases. “The epidemic situation in China has been basically controlled and no more people have been infected. At present, most of the increased cases are imported from abroad. We need to pay special attention to asymptomatic infections. ” Zhong Nanshan said that the incubation period of asymptomatic patients is mostly 3 to 7 days, and the highest incubation period may be 14 days. During the incubation period, the patient may be asymptomatic or very mild. Data show that about 50% of patients do not have fever, fatigue, cough, but may appear the first symptoms. Close contacts of infected persons and those who come back from the outbreak community should be paid more attention to and protected to prevent further spread of the epidemic.
