On April 27, Wang Guiqiang, chief physician of the Department of Infectious Diseases of Peking University First Hospital, said at the briefing of the State Council Office that wearing masks is the most effective prevention and control measure for the new coronary pneumonia epidemic. "Wearing a mask does not alleviate the occurrence of respiratory infectious diseases" is a misunderstanding. In fact, from the experience of China, wearing a mask is very important for preventing and controlling the spread of new coronary pneumonia, and it has also proved to be effective. Wang Guiqiang said that because there are many asymptomatic infected persons, he and the people around him do not know that he has been infected. If he does not wear a mask, the asymptomatic infected persons will become an important source of infection of the new coronavirus. Previously, relevant research by the Chinese University of Hong Kong has also shown the role of wearing masks. (Wang Shibo)
