During the long holiday of May 1st, the country experienced high temperatures in many places, and many people repeatedly struggled between the fight against epidemics and heatstroke. In the scorching sun, wearing a mask to cover his face with sweat was really unbearable, and even caused skin inflammation. But without the mask, there is the risk of being infected by the new coronavirus, what should I do?
Professor Yang Zhanqiu of the Institute of Medical Virology of Wuhan University told the Global Times reporter on the 5th, "According to China's national conditions and the reality of the current epidemic, I think that masks must still be worn in crowded places, but if you walk normally outdoors, you can Wear a mask because there are basically no viruses in the domestic natural environment. " He said that after entering the summer, especially in the southern part of China, the temperature is high, and even wearing a mask will soon be wet by sweat and lose its protective effect. "Pedestrians may be safer without wearing a mask when walking on an open road outside. Because the purpose of wearing a mask is to prevent bacteria and viruses, but if the mask is wet by sweat, it will not only fail to provide protection, but also Causes the bacteria exhaled from the mouth to attach to the mask, causing the breeding of bacteria and viruses. "
However, he emphasized that it is still safer to wear masks in public places, especially in crowded areas, such as taking buses, going to hospitals, and in closed environments such as high-speed rail stations and airports. Moreover, these occasions basically have air conditioning, and the impact of high temperature is not big.
Yang Zhanqiu also said that as the national anti-epidemic situation improves, some protective measures can be considered for gradual relaxation. "We now pay attention to scientific prevention and control, first of all we must respect science. New coronary pneumonia is mainly an infectious disease that is prevalent in winter and spring and autumn. If you wear a mask all year round, then it is not called science." He believes that prevention Imported infections can also be used to prevent epidemic rebound. The premise of protection is to have a clear source of infection. At present, in special occasions such as airports and hospitals, good protection is still necessary. If there are imported cases at the airport, there is still a certain risk; there may also be fever patients to see the doctor at the hospital. We cannot guarantee that all patients in the hospital will not have a new coronavirus infection, so we must take good protection. However, for non-special occasions, such as supermarkets, movie theaters, restaurants, etc., there is basically no source of infection, so the risk is not great.
