Which of the following is NOT a symptom of TB?

Severe headaches are not typically associated with tuberculosis (TB) as primary symptoms. TB is primarily a respiratory infection caused by the bacterium Mycobacterium tuberculosis. The hallmark symptoms of TB include night sweats, chills, fatigue, a persistent cough, fever, and weight loss.

Night sweats result from the body's immune response to the infection, while chills and fatigue are also common reactions related to the overall illness and the body's effort to fight off the infection. Severe headaches, while they can occur in a variety of other infections or health conditions, are not characteristic symptoms of TB specifically. It’s important to recognize that while headaches can happen in a wide range of illnesses, in the context of tuberculosis, they are not a defining feature of the disease.
