The second symptom of tuberculosis is fever, with fluctuations in body temperature, usually low fever, between 37 and 38.5 degrees, especially after noon or after exertion, and gradually decreasing in the evening. In the early stage of the disease, the cough is not obvious, and occasionally a dry cough may appear in the early morning.
