Coughing That Lasts Three Weeks or Longer


There are two forms of tuberculosis: active and latent tuberculosis. The latter is when people have TB but do not develop any of the symptoms. Active tuberculosis, on the other hand, means you get sick. The first symptom you develop is a persistent cough that doesn’t go away, even after 3 weeks.

Another symptom to be wary of is coughing up blood. Someone who has contract tuberculosis may notice that they are coughing up blood or even a substance known as sputum, a mucus present within the lungs and airways. Regardless of the frequency of the coughing fits, once you see blood, you need to go to a doctor or the emergency room immediately.
