The incubation period of Covid-19 pneumonia is generally 1 to 14 days, and most of them are 3 to 7 days, but there are also reports that the incubation period of very few patients exceeds two weeks.
The source of infection of the new coronavirus pneumonia is mainly patients with new coronavirus infection and asymptomatic infections, which are contagious during the incubation period and are highly contagious within 5 days after the onset of the disease.
Therefore, even if the patient is asymptomatic, it will be highly contagious. The incubation period refers to the time from the day of infection with the new coronavirus until the first symptoms appear, and the period in between is the so-called incubation period. However, the date of the onset of symptoms in patients is determined by the patient's recollection, so it may be imprecise and its accuracy is questionable.
It is also necessary to know what the first symptoms of patients are. The first symptoms of new coronavirus patients are different. The most common ones are fever, dry cough, and fatigue. The fever can be moderate to low fever or high fever, but some patients do not fever. Some patients only present with headache, muscle aches, runny nose, sneezing, fatigue, loss of appetite, abdominal pain, diarrhea, etc. Conjunctivitis is the first symptom, and some patients have mild symptoms and are easily overlooked or confused.
Therefore, it takes a lot of epidemiological work to know how long the incubation period of some patients is.
Patients in the incubation period are contagious. Once it is determined that they are patients in the incubation period, they should be isolated and observed immediately and their symptoms should be closely monitored. If you have symptoms related to the new crown, you should be isolated and treated immediately. Children and some people with strong immunity may not have symptoms, and some people will have mild symptoms, mainly low-grade fever or symptoms of upper respiratory tract infection. These people generally have a better prognosis.
