(We Chinese in America Media Editor Tang Zhao, January 22, 2022) This wave of Omicron virus is extremely contagious. In the two years since the development of the new coronavirus epidemic, the virus has been constantly changing, but if the policy and the direction of epidemic prevention cannot keep up with the development trend of the epidemic, more resources will be wasted, and the people will be hurt. Expert analysis shows that this wave of Omicron virus is extremely contagious. Many people have begun to buy N95 masks, but they do not know how to use them. Some people also heat and disinfect N95 masks, which is a wrong approach.

Zhang Zhibei, Distinguished Chair Professor of National Taiwan University and Honorary Distinguished Professor of the US Naval Research Institute analyzed that the Omicron variant is extremely contagious. The US government finally confirmed that cloth masks are useless. It is recommended that people wear N95 or KN95. It is a serious mistake to clean or sterilize the hard-to-buy N95 masks like cloth masks.

He analyzed that because washing, disinfection or heating will destroy the three-layer filter and electrostatic adsorption function of the inner layer of the N95 mask, once the function is destroyed, the virus may penetrate through the gap of the filter, otherwise the filter will be blocked. The user may feel that the breathing is smoother by letting the breathing air come in and out from the surrounding area, but in fact, the effectiveness of the mask is destroyed, which is equivalent to not wearing a mask.

Zhang Zhibei analyzed that the correct approach should be to use four or five N95 masks in turn and put them in an open paper bag after using them every day. If there is a virus on the mask, it will lose its activity after one or two days. If you go to a place with a new COVID patient, you will immediately throw it away when you leave. This way, at least one mask can be reused for many days, until it is damp, dirty, or has signs of odor, or when the earring straps become loose and lose their elasticity, and the edge of the mask has a gap before discarding. This is more environmentally friendly and can improve the efficiency of the use of masks.
