World Tuberculosis Day, is observed annually on March 24 each year, to build public awareness about the virulent, infectious disease tuberculosis (TB) and efforts to eliminate it. In 2012, 8.6 million people fell ill with TB, and 1.3 million died from the disease, mostly in the Third World. World TB Day is one of eight official global public health campaigns marked by the World Health Organization (WHO), along with World Health Day, World Blood Donor Day, World Immunization Week, World Malaria Day, World No Tobacco Day, World Hepatitis Day and World AIDS Day.
Tuberculosis (TB) is an infectious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. Tuberculosis generally affects the lungs, but can also affect other parts of the body. Most infections do not have symptoms, in which case it is known as latent tuberculosis. About 10% of latent infections progress to active disease which, if left untreated, kills about half of those affected. The classic symptoms of active TB are a chronic cough with blood-containing sputum, fever, night sweats, and weight loss. It was historically called “consumption” due to the weight loss. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke.
March 24 commemorates 24 March 1882 when Dr Robert Koch astounded the scientific community by announcing the discovery of Mycobacterium tuberculosis, the bacterium responsible for tuberculosis, to a small group of scientists at the University of Berlin’s Institute of Hygiene. According to Koch’s colleague, Paul Ehrlich. Koch explained the aetiology of tuberculosis presenting many of his microscope slides and other pieces of evidence. At the time of Koch’s announcement in Berlin, TB was raging through Europe and the Americas, causing the death of one out of every seven people. Koch’s discovery opened the way toward diagnosing and curing tuberculosis.
In 1982, on the one-hundredth anniversary of Robert Koch’s presentation, the International Union Against Tuberculosis and Lung Disease (IUATLD) proposed that March 24 be proclaimed an official World TB Day as part of a year-long centennial effort by the IUATLD and the World Health Organization under the theme “Defeat TB: Now and Forever.” However World TB Day was not officially recognized as an annual occurrence by WHO’s World Health Assembly and the United Nations until, 1995, when WHO and the Royal Netherlands Tuberculosis Foundation (KNCV) hosted the first World TB Day advocacy planning meeting in Den Haag, Netherlands. In 1996, WHO, KNCV, the IUATLD and other concerned organizations joined to conduct a wide range of World TB Day activities.
For World TB Day 1997, WHO held a news conference in Berlin during which WHO Director-General Hiroshi Nakajima declared that “DOTS is the biggest health breakthrough of this decade, according to lives we will be able to save.” WHO’s Global TB Programme Director, Dr. Arata Kochi, promised that, “Today the situation of the global TB epidemic is about to change, because we have made a breakthrough In developing health management systems that makes it possible to control TB not only in wealthy countries, but in all parts of the developing world, where 95 percent of all TB cases now exist.”
By 1998, nearly 200 organizations conducted public outreach activities on World TB Day. During its World TB Day 1998 news conference in London, WHO for the first time identified the top twenty-two countries with the highest number of TB cases. In 1999, over 60 key TB advocates from 18 countries attended the three-day WHO/KNCV planning meeting for World TB Day. U.S. President Bill Clinton marked World TB Day 2000 by administering the WHO-recommended DOTS treatment to patients at the Mahavir Hospital in Hyderabad, India. According to Clinton, “These are human tragedies, economic calamities, and far more than crises for you, they are crises for the world. The spread of disease is the one global problem for which . . . no nation is immune.” In Canada, the National Collaborating Centre for Determinants of Health noted on World TB Day 2014 that 64% of TB cases reported nationally were among foreign-born individuals and 23% among Aboriginal people, highlighting TB as a key area of concern about health equity.
