The symptom of fatigue itself is a non-specific symptom, and when the body gets sick, the first symptom it may show is fatigue and a desire to rest. Therefore, the presence of fatigue and weakness during the epidemic phase does not in itself prove infection with novel coronavirus. The most reliable way to determine infection with novel coronavirus must be the pathogenicity test, i.e., a positive test for nucleic acid nucleic acid of the novel coronavirus, or gene sequencing consistent with the characteristics of the novel coronavirus, which is the most reliable way to determine the diagnosis. It cannot be determined solely on the basis of fatigue and weakness, as many other diseases present may be accompanied by symptoms of fatigue and weakness. Content source: Dr. Yurai
