Night sweats are commonly associated with which infectious disease?

• A. Tuberculosis
• B. Osteoarthritis
• C. Migraine
• D. Hypertension

Answer: (A)

Night sweats signal a systemic process, and tuberculosis is a classic infectious disease linked to them. The body's immune response to Mycobacterium tuberculosis releases cytokines such as TNF-α and IL-1, which promote fever and profuse sweating, especially at night when body temperature regulation shifts during sleep. Clinically, TB often presents with a triad of prolonged cough, fever, and night sweats, along with weight loss. The other conditions listed are not typically associated with drenching night sweats: osteoarthritis mainly causes joint pain and stiffness, migraine is characterized by episodic headaches, and hypertension may cause headaches but not a hallmark pattern of night sweats.
