Which of the following is NOT a symptom of Active Tuberculosis?

Active Tuberculosis (TB) is known for presenting with a variety of symptoms, and understanding these symptoms is crucial, especially in a detention setting. A persistent cough lasting three weeks or longer is a typical indication of active TB, whereas a cough for less than three weeks would not typically signal the presence of active disease.

Chest pain, fever and chills, and weight loss are well-documented symptoms associated with active TB. Chest pain may occur due to inflammation of the lung tissue or surrounding structures. Fever and chills often accompany infections like TB as part of the body's immune response. Moreover, weight loss is commonly experienced due to a lack of appetite and the body’s increased metabolic demands while fighting the infection.

Thus, the symptom of a persistent cough for less than three weeks does not align with the recognized indicators of active TB, making it the correct choice for what is NOT a symptom of this condition.
