The most important route of transmission of novel coronavirus pneumonia is through close contact between people, including respiratory droplet transmission between people and close physical contact, and also partly through aerosol transmission from confined spaces, but this route of transmission is generally relatively rare. Therefore, the main thing to prevent the spread of New Coronary Pneumonia is to avoid contact with outside people, and to wear a good mask when in contact. The best masks are medical surgical masks or medical N95 masks, disposable general medical masks to effectively block coronavirus infestation, and other masks can also prevent droplet transmission. In addition, hand disinfection should be done. Hand disinfection can be done with 75% alcohol or hand sanitizer containing alcohol. You can also disinfect your hands with running water. Good hand disinfection is necessary to effectively block the transmission pathway brought about by close contact.
