History of World TB Day Learn why we observe World TB Day on March 24th.

Each year, we recognize World TB Day on March 24. This annual event commemorates the date in 1882 when Dr. Robert Koch announced his discovery of Mycobacterium tuberculosis, the bacillus that causes tuberculosis (TB).

Although TB is preventable and curable, many people in the United States still suffer from this disease. Anyone can get TB, and our current efforts to find and treat latent TB infection and TB disease are not sufficient. Misdiagnosis of TB still exists and health care professionals often do not “think TB.”

The U.S. theme for World TB Day 2018 is “Wanted: Leaders for a TB Free United States. We can make history. End TB.” CDC and its domestic and international partners, including the  National TB Controllers Association, Stop TB USA, and the global Stop TB Partnership are working together to eliminate this deadly disease. But we need your help.

Be sure to check back for more information and resources as we get closer to World TB Day.  You can also follow us on Twitter @CDC_TB and Facebook @CDCTB and sign up for email updates through GovDelivery.

Join CDC’s World TB Day Thunderclap, and share the End TB message March 23rd at 2:00 p.m. EDT/11:00 a.m. PDT, spreading an idea through Facebook, Twitter, and Tumblr that cannot be ignored. We need 100 supporters for the Thunderclap to take effect, so please visit before March 23 to sign up and learn more.
