Which of the following is a symptom of tuberculosis?

• A. Rash on arms.
• B. Migraine headaches.
• C. Frequent sneezing.
• D. Bad cough for 3 weeks or longer.

Answer: (D)

Tuberculosis most often presents with a respiratory symptom that sticks around for weeks. A bad cough lasting three weeks or longer fits this pattern and is a classic sign that would prompt further medical evaluation for TB, especially in settings like corrections where screening and contact tracing are important. The other symptoms listed don’t align with the typical TB picture: a rash on the arms is usually from skin conditions or allergies, migraines are not a hallmark of TB, and frequent sneezing is more associated with allergies or common colds. So, the persistent, long-lasting cough is the symptom that best points to tuberculosis. If someone has this sign, it’s important to seek medical assessment for proper testing and diagnosis.
