Why should we wash our hands frequently during the epidemic?


       With the spread of COVID-19 pandemic, people's awareness of prevention has also been significantly improved. Daily protection is essential. For example, we must pay attention to wearing masks and try to reduce the frequency of going out. Even if we go out, stay away from crowded places. At home at ordinary times, should ventilate more, disinfect more, wash hands frequently, etc.

Whether expert or some professionals, when introducing a layer of protection, they repeatedly emphasize that everyone must wash their hands frequently. Why is that?

Mainly because coronavirus is very contagious. Mainly through respiratory tract, such as droplets. Because the nucleic acid of the pathogenic bacteria is single-stranded RNA, it can grow in primary cells of human kidney, intestine, and lung. After blind passage, it can enhance the pathogenicity of coronavirus. Coronavirus is sensitive to ether, chloroform, medical alcohol (75%), and ultraviolet rays, which can eliminate the virus on the surface. And we live in a world full of bacteria and viruses. In life, if a patient infected with viruses and bacteria adsorbs droplets to objects such as doorknobs, bus railings, elevator buttons, etc. by sneezing, coughing, etc., then it is easy for others to touch these objects by accident, which leads to contamination of the hands.
