The symptoms of novel coronavirus infection during the incubation period vary from person to person. Generally, infected persons have no obvious symptoms during the incubation period, while some infected persons may experience some mild symptoms such as malaise. Novel coronavirus pneumonia has the ability to be contagious during the incubation period, so patients in the incubation period may become a mobile source of infection. Therefore, it is important to protect yourself during the outbreak, and if you find any uncomfortable symptoms, immediately isolate and observe them and seek medical attention in a timely manner.
