Occurring annually on March 24th, World TB Day raises global awareness that tuberculosis (TB) remains one of the leading deadly infectious diseases worldwide, infecting nearly 30,000 people and killing over 4,000 per day. The date commemorates the day in 1882, when Dr. Robert Koch announced he had discovered Mycobacterium tuberculosis, the bacteria that causes TB. World TB Day helps to raise public awareness about the devastating health, social and economic impact of TB, and urge acceleration of efforts to end the global TB epidemic.

Symptoms of TB disease include cough, chest pain, weight loss, fever, and night sweats. For more information, visit:
