What are the common symptoms of tuberculosis?

The symptoms of tuberculosis (TB) can vary depending on whether the infection is active or latent. Here are the common symptoms associated with active TB disease:

1. Persistent Cough: A cough that lasts for three weeks or longer is a common symptom of TB. The cough may produce phlegm or blood.

2. Weight Loss: Unexplained weight loss is a characteristic symptom of active TB. This can occur due to a variety of factors, including loss of appetite.

3. Fatigue and Weakness: Individuals with TB may experience persistent fatigue and weakness.

4. Fever: A low-grade fever, often occurring in the afternoon or evening, is a common symptom of TB.

5. Night Sweats: Profuse sweating, especially at night, is another symptom associated with TB.

6. Chills: Some people with TB may experience chills or shivering, particularly during fever episodes.

7. Loss of Appetite: A diminished appetite is often observed in individuals with active TB.

8. Pain in the Chest: Chest pain may occur due to inflammation of the lungs or the formation of cavities in the lung tissue.

9. Shortness of Breath: As TB progresses, individuals may experience difficulty breathing and shortness of breath.

It's important to note that these symptoms are not exclusive to TB, and other respiratory illnesses may present with similar signs. If someone experiences these symptoms, especially if they persist for an extended period, it is crucial to seek medical attention for proper diagnosis and treatment. Early detection and treatment are key to managing TB effectively.
