The purpose of home isolation is to prevent the formation of second- and third-generation cases by physically isolating the patient and stopping the patient from remaining and spreading in the community. When there is a large number of asymptomatic close contacts or potential patients, home isolation should be used as an important option to address problems that cannot be addressed by treatment facilities. If any symptoms appear, hospital visits are required. On the one hand early detection of close contacts whether the disease, early detection, early diagnosis, early treatment, during the 14 days of isolation can be timely and effective treatment. On the other hand, it is more important to guard the health and safety of other people and prevent the close contacts from transmitting the virus to the healthy people around them during the incubation period.
