Signs and symptoms of TB
Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. The signs and symptoms of TB vary depending on whether it is active or latent TB infection.
Signs and symptoms of active TB include:
1. Persistent coughing: This is usually a productive cough that lasts for three weeks or longer, and may produce blood or phlegm.
2. Fatigue: Feeling tired and weak is a common symptom of TB.
3. Weight loss: Unexplained weight loss can occur, and individuals may experience a decreased appetite.
4. Fever: A low-grade fever, usually in the afternoon or evening, is a common symptom.
5. Night sweats: Intense sweating, particularly at night, is a characteristic symptom of TB.
6. Chest pain: Pain or discomfort in the chest may occur, particularly while coughing or breathing deeply.
7. Shortness of breath: Difficulty breathing or feeling breathless can be present.
8. Swollen lymph nodes: Enlarged lymph nodes, usually in the neck or armpits, can be a sign of TB.
9. Loss of appetite: A reduced desire to eat or a general feeling of malaise may occur.
10. General discomfort: Individuals may experience a feeling of ill health or just not feeling well.
It is important to note that latent TB infection typically does not cause any symptoms. However, if the latent infection becomes active, the signs and symptoms listed above may develop.
If you suspect you may have TB or are experiencing any of these symptoms, it is important to seek medical attention for diagnosis and appropriate treatment.
