How many days is the incubation period in COVID-19?

COVID-19 usually refers to novel coronavirus, and the general incubation period is 1- 14 days. The specific incubation time has a certain relationship with personal physique. Even if the patient is in the incubation period, it is contagious and isolation measures are needed.

Novel coronavirus is an infectious disease caused by novel coronavirus infection, which belongs to pulmonary inflammatory disease and can be spread by droplets and contact. Novel coronavirus does not necessarily get sick immediately after invading human body, but has a certain incubation period. Generally, it is because novel coronavirus does not reach a certain number after entering the body, and it needs to lurk in the body for a period of time to breed in large quantities, so that novel coronavirus will get sick only when it accumulates to a certain extent. Clinically, the incubation period of novel coronavirus is usually 1- 14 days, and most patients will get sick within 3-7 days after infection. The length of the incubation period is related to the patient's personal physique. If the patient's personal constitution is good and the immune function is strong, the incubation period will be longer. If the patient's personal constitution is poor, the immune function of the body is weak, the incubation period is relatively short, the onset speed is fast, and the symptoms are obvious after the onset. Typical symptoms are fever, cough, weakness and so on. It may also lead to a decline in sense of smell and taste. Mild symptoms are not obvious, and severe symptoms may cause discomfort such as dyspnea.

If you have fever and other unwell symptoms, you should go to the fever clinic or infection department of the hospital in time, and take temperature measurement and nucleic acid detection under the guidance of a doctor. At the same time, you should take isolation measures to avoid infection. In the outbreak stage, we should pay attention to protective measures, try to avoid going to crowded places, wear masks correctly when going out, and take protective measures such as opening windows for ventilation and washing hands frequently, which will help reduce the probability of infection.
