Cough: The symptoms are more serious, mostly dry cough, which can be relieved when the condition is usually cured. 2. Loss of sense of smell: some patients have symptoms of loss of sense of smell during the onset of the disease, but the sense of smell is not restored after the disease is cured. Even a small number of patients still have olfactory dysfunction several months after the disease has recovered. 3. Fatigue and weakness: A very small number of patients still have prolonged fatigue and weakness and are unable to perform heavy physical labor after the disease has recovered.
