tuberculosis (TB)

Tuberculosis (TB) is a contagious bacterial infection primarily affecting the lungs, though it can impact other parts of the body. It spreads through the air when an infected person coughs or sneezes. Symptoms include a persistent cough, chest pain, weight loss, fever, and night sweats. While TB can be serious, it is treatable with a course of antibiotics that usually lasts several months. Early diagnosis and proper treatment are crucial to prevent its spread and complications. Vaccination can also help protect against TB in some regions.
