World Tuberculosis Day, annually observed on 24 March is a campaign to build public awareness about tuberculosis (TB) and efforts to eliminate the disease. Around 1.3 million died from the disease and 8.6 million people fell ill in 2012.

This day is one of eight official global public health campaigns by the World Health Organization (WHO), along with World Blood Donor Day, World Health Day, World Immunization Week, World No Tobacco Day, World Hepatitis Day, World Malaria Day, and World AIDS Day. Netizens also actively showed support on Twitter by spreading the message to create awareness about the disease.
