Simple cough is also very common in clinical practice, and there are many complicated factors that can trigger simple cough, so it is not necessarily a cold.

Of course, patients with a cold can also have a simple cough, which can also be seen in chronic pharyngitis, cough variant asthma, allergic cough, etc. Therefore, a clear diagnosis of simple cough requires timely correlation with the patient's history and other clinical symptoms, as well as relevant auxiliary examinations.

Commonly, colds are mostly viral infections. If it is uncertain whether the simple cough is caused by a cold, one can check if the lymphocytes are elevated through blood tests, and if the white blood cells and C-reactive protein are normal, through some auxiliary examinations, then it can be determined whether the simple cough is due to a cold.
