Novel coronaviruses are transmitted mainly by droplets and contact, and are not generally airborne. Because the air outside is always circulating, novel coronaviruses cannot persist for long and are usually safer. Therefore, it is recommended to ventilate the room often and keep it clean. Do personal protection on a daily basis, avoid crowded places, wear a mask when you go out, avoid close contact, and keep a safe distance of 2 meters when interacting with people. Try to avoid touching public facilities such as door handles and faucets and keep your hands clean.
