The incubation period for novel coronavirus pneumonia infection is 1-14 days, with most being 3-7 days. Most people infected with novel coronavirus pneumonia have no symptoms during the incubation period, which is a time of greater risk because of the lack of knowledge and the possibility of infecting others. Novel Coronavirus Pneumonia starts with fever, and the earliest symptoms may include fever, dry cough, and malaise, followed by dyspnea, breathlessness, and diarrhea, as well as runny nose and coughing up sputum, which are relatively rare. So the initial period is usually characterized by fever, or there may be no manifestation during the incubation period. Content source: Dr. Yurai
