Novel coronavirus can be transmitted to people through objects because it is present in droplets in the respiratory tract and when it lands on the surface of an object, a person may become infected upon contact. The novel coronavirus can be ejected from the body via droplets when talking, coughing, or sneezing. When droplets containing the virus fall onto the surface of an object, a person may become infected with the novel coronavirus if he/she touches the virus on the surface of the object with his/her hands and does not wash his/her hands or pay attention to hand hygiene, and then touches his/her own mouth, eyes, or nose. Therefore, in order to prevent the new coronavirus, it is important to pay close attention to hand hygiene in addition to wearing a mask properly. Do not touch mucous membrane areas with contaminated hands. Sterilize and wipe items suspected to be contaminated regularly.
