Tuberculosis (TB) is a serious infection that usually affects the lungs. It can cause a cough lasting 3 weeks or longer, cest pain, and coughing up blood or sputum. Other symptoms include fatigue, weight loss, loss of appetite, chills, fever, and night sweats.
Tuberculosis is treatable, but recognizing its warning signs early is essential for timely testing and care. If you have a persistent cough or symptoms such as fever, night sweats, weight loss, or chest pain, consult a healthcare provider promptly.
