Pioneers in TB control in Africa, India win new UN-backed health prize

A tireless advocate for people infected with both tuberculosis and HIV in Zambia and the manager of the national TB control programme in India today won a prestigious new United Nations-backed health prize for their efforts to transform control of the debilitating but curable disease that kills some 5,000 people every day.

Winstone Zulu from Zambia and L.S. Chauhan from India became the first winners of the

The Stop TB Partnership Kochon Prize, inaugurated this year by the Partnership, a network of more than 500 organizations whose secretariat is housed at the UN World Health Organization (WHO) headquarters in Geneva.

The Kochon Foundation was created in 1973 by the late Chong-Kun Lee, Chairman of the Chong Kun Dang Pharmaceutical Corp., one of the first TB drug manufacturers in Korea.

Mr Zulu himself was cured of tuberculosis, although all of his four brothers died of the disease. He is a co-founder of Kara-Kabwe Programmes for Kara Counselling, a provider of HIV/AIDS counselling in Zambia, and was Co-President of TBTV.org, one of the first global organizations of people with TB and HIV/AIDS.

Dr. Chauhan is Deputy Director-General (Tuberculosis) and Programme Manager of the National TB Control Programme in India. Since 2002 he has overseen the rapid expansion of the DOTS TB-control program in India, a remarkable accomplishment in the country that bears the world’s highest TB burden.

TB is a global public health menace of catastrophic proportions. Like the common cold, it spreads through the air. Only people who are sick with TB in their lungs are infectious. When infectious people cough, sneeze, talk or spit, they propel TB germs, known as bacilli, into the air. A person needs only to inhale a small number of these to be infected.

Left untreated, each person with active TB will infect on average 10 to15 people every year, but infected people will not necessarily become sick. The immune system walls off the bacilli which, protected by a thick waxy coat, can lie dormant for years. When someone's immune system is weakened, the chances of becoming sick are greater.

According to WHO, someone in the world is infected every second. Overall, a third of the world’s population is currently infected with the bacillus and 5 to 10 per cent of these, if they are not also infected with HIV, become sick or infectious some time during their lives. People with both HIV and TB infection are much more likely to develop TB.

The largest number of new cases in 2004 occurred in South-East Asia, which accounted for 33 per cent of the global total. But the estimated incidence per capita in sub-Saharan Africa is nearly twice that of South-East Asia, at nearly 400 cases per 100,000.
