Browsing: Tuberculosis

Tuberculosis (TB) is a highly infectious disease primarily affecting the lungs, caused by the bacterium Mycobacterium tuberculosis. It can also impact other parts of the body, including the kidneys, spine, and brain. TB is spread through the air when a person with active pulmonary TB coughs, sneezes, or speaks, releasing droplets that others can inhale. The disease manifests with symptoms such as chronic cough, fever, night sweats, and weight loss. While TB is preventable and curable, it remains a major global health challenge, particularly in developing countries with high rates of HIV or limited healthcare infrastructure. Treatment involves a long course of multiple antibiotics over a period of at least six months, and the emergence of drug-resistant strains has made management increasingly complex and prolonged.
