The novel coronavirus is mainly transmitted by droplets, but it can also be transmitted by contact. Therefore, door handles, elevator buttons, handrails, glass and seats on transportation should be disinfected frequently to prevent exposure to the new coronavirus. A more effective way to prevent contact transmission is to go out without touching or touching, and to wash your hands regularly when you get home. When you get home, be sure to wash your hands first, or spray your clothes with 75% alcohol to disinfect them.
