Novel coronaviruses have the potential to be transmitted by contact, which is the mode given in the fifth edition of the Novel Coronavirus Guidelines. The modes of transmission given in the guidelines include respiratory-associated droplets, and close contact is currently the definitive mode of transmission by contact. Close contact means living and working together for a long period of time, and even sharing the bathroom can be a form of close contact, which may cause novel coronavirus infection. Therefore, you should try to isolate yourself, open windows, and wash your hands and face frequently. It is also important to pay attention to secretions, eyes, ears, nose, mouth and other exposed organs may be transmitted through close contact, so it is more important to do isolation protection.
