Patients with tuberculosis tend to exhibit symptoms such as cough, expectoration, low-grade fever, night sweats, afternoon feverishness, and blood in sputum in the early stages. Systemic symptoms of tuberculosis include afternoon feverishness, which refers to the body temperature starting to rise in the afternoon and returning to normal by early morning. Night sweats refer to sweating profusely during sleep, which stops upon waking. These tuberculosis-related symptoms are commonly seen in the early stages of the disease.
