Active TB disease

Active tuberculosis (TB) disease is a serious infection caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can impact other parts of the body. When someone has active TB, they may experience symptoms like a persistent cough, fever, night sweats, and weight loss. The disease is contagious and spreads through the air when an infected person coughs or sneezes. Treatment involves a long course of antibiotics, typically lasting several months, to eradicate the bacteria and prevent further transmission. Early diagnosis and treatment are crucial for recovery and public health.
