Asymptomatic novel pneumonia means that a novel coronavirus infection has been clinically diagnosed but has no symptomatic manifestations. This means that the patient has coronavirus in his or her body but no clinical manifestations. These patients are most often seen with mild, imported pneumonia, in which the infection is transmitted from an infected area to a local population, and some of these patients are infected but do not have clinical manifestations. The new coronavirus pneumonia is now included in the statutory category B infectious diseases, and even if there are no symptoms, it should be isolated and observed in a designated hospital, or treated symptomatically. This is the reason for the 14-day isolation after long-distance travel, as it is possible to be an asymptomatic infected person. If the disease develops during the isolation period of 14 days or less seek prompt medical attention. If there is no illness, it can be largely assumed that there is no infection with novel coronavirus pneumonia. Content source: Dr. Ararai
