COVID-19 is particularly contagious, and everyone in COVID-19 is familiar with it. This virus can be transmitted through human saliva. When saliva in the crowd is inhaled by others through airflow, it may be infected. Moreover, the infection rate is very high, which is particularly harmful to people. The most critical communication between people will increase geometrically, which is quite terrible.
COVID-19 can survive by writing and spread it to others. Viruses can also survive on people's commonly used items, and will survive for a long time. For example, our most commonly used mobile phones, bus doorknobs, personal rice bowls and chopsticks, and computer keyboards used in offices are always the items that patients have touched, and the virus can basically survive for a long time. This has also brought us great trouble.
Patients using CT or medical equipment alone can prevent infection from the root, and let COVID-19 infected people use all kinds of medical equipment alone, thus eliminating the chance of reinfection. So as to completely cut off the transmission. If patients and uninfected people are allowed to use the same equipment, COVID-19 is likely to stay on this equipment and survive, thus infecting the people being examined, and the hospital is a place with a particularly large flow of people. Once this infection occurs, the consequences will be unimaginable. Therefore, it is still necessary to use the equipment used by infected people separately from the equipment used by uninfected people.
I hope everyone will wear masks when they go out, take public transport or go to places with heavy traffic, and wash their hands when they get home. Also, don't keep changing the mask. The use of masks has a long life. Please consult the retail store for details. The service life of different types of masks is different. Wear a mask when you go out and wash your hands frequently when you go home.
