The main routes of transmission of the new coronavirus are droplet transmission and contact transmission. Therefore, the possibility of droplet transmission can be reduced by wearing a mask. Contact transmission is mainly through body and hand contact. Items touched by patients with New Coronavirus may have New Coronavirus. If the hands touch New Coronavirus and then touch the eyes, nose and oral mucosa, it can lead to infection. Therefore, hand washing is the main way to interrupt contact transmission. Other ways to reduce contact transmission include changing payment methods, such as using WeChat payments; and not touching items in public places such as elevator buttons. In addition, make frequent hand washing a major step in blocking contact infection, such as washing hands before and after meals, washing hands before and after pooping, washing hands when coming out and going in, and washing hands when coming into contact with other people, pets or delivery. If you clean up the virus in time with running water and disinfectant, and if you do not touch your mucous membranes, eyes, nose and mouth without washing your hands, you will not be infected through indirect means. Therefore, the main preventive measure for contact infection is to wash hands regularly. Content source: Dr. Yurai
