Patients with confirmed cases of novel coronavirus pneumonia are usually admitted to sentinel hospitals where they are isolated. Patients are also required to wear surgical masks in their living room wards, which on the one hand reduces the risk of infection among medical staff and on the other hand reduces cross-infection between patients in the same ward. Generally speaking, patients who receive the same ward are all patients with novel coronavirus pneumonia, so there is no possibility of coronavirus infection among them. Instead, it is more important to pay attention to whether there are any other pathogens other than the novel coronavirus co-infections that lead to interactions. For prevention of novel coronavirus pneumonia in the general population, wearing a surgical mask is generally sufficient. If there is no high-risk exposure or if you are in a crowded place, wearing a surgical mask on a daily basis is sufficient. Source: Dr. Yurai
