Neo-crown virus is mainly transmitted through respiratory droplet transmission and close contact, but it can also be transmitted through aerosol transmission in relatively closed environments and through contact with objects contaminated with the virus. Neo-crown virus can be transmitted through respiratory droplet transmission. If a healthy person speaks face-to-face with a patient with neo-crown pneumonia, or if a patient with neo-crown pneumonia develops symptoms such as coughing or sneezing, neo-crown virus may be transmitted to a normal person through droplet transmission from the oral and nasal cavities. Neocoronavirus can be spread through close contact, which refers to living and working in the same area and possessing a number of commonly used items, such as towels, mugs, and doorknobs. New coronavirus can be spread through aerosol. When a person with new coronavirus pneumonia passes through a certain space area, he/she coughs and sneezes, and the virus is discharged and suspended in the air to form an aerosol. When a healthy person passes through this space area and inhales the aerosol containing the virus, he/she will also be infected with new coronavirus. New coronavirus can be transmitted through contact with items contaminated with the virus. New coronavirus can be attached to the surface of various items such as wallets, cell phones, and couriers, and healthy people can be infected with new coronavirus when they come into contact with these items with new coronavirus attached to them. Therefore, it is important to pay attention to the protection in daily life, go out and wear a mask, pay attention to hand hygiene. Tip: On December 26, 2022, the National Health Commission announced that the names of “new coronavirus pneumonia” and “new coronavirus pneumonia” have been changed to “new coronavirus infection”.
