After "Yangkang", the cough will continue for a while. The cough does not mean that the infection is increasing.However, if the symptoms of cough are severe or continuously not alleviated, especially when the fever or continuous fever continues, accompanied by hypoxia (decreased oxygen saturation) or shortness of breath, and shortness of qi after activity, you need to be alert to pneumonia caused by new coronary virus.Go to the hospital and check the chest CT.
