Asymptomatically infected people with the new coronavirus may be a danger to themselves and are contagious, and their danger is related to their surroundings; the more densely populated a place is and the less it is isolated, the more contagious it is.
Some of the asymptomatic infected people, usually do not appear obvious clinical symptoms, may be because of their own strong immune system, the virus will be completely killed, in fact, the impact on the body is not great.
But if you do not get timely and effective treatment, there is also a part of the patient, it is likely to be from asymptomatic, began to show the corresponding clinical symptoms one after another. For example, fever, cough, fatigue, dyspnea, etc., so the condition will be aggravated, and there is also a certain impact on the prognosis.
Asymptomatic infected people, if not detected in time, without early isolation for observation and treatment, it is easy to lead to outbreaks of infection. Especially if there are more people in close contact around them and there are immunocompromised people around them are more susceptible to infection.
For asymptomatic infected people, also need early isolation, general isolation at least two weeks, and after several times negative nucleic acid test can be lifted isolation, in the isolation period to observe whether the corresponding clinical symptoms, early detection of close contacts.
