Drug-resistant TB is on the rise, with some strains immune to all major drugs Extensively resistant TB reported in 92 countries but is likely to be in many more Aboutnew drug-resistant TB cases reported worldwide in "It's probably in every country," says expert Vital Signs is a monthly program bringing viewers health stories from around the world.
CNN "Sometimes I ask myself, why me? Why did this have to happen again? He's had tuberculosis for more than two years but it's not the first time he's been infected.

Dense housing, shared living space, poor ventilation, poor nutrition and poor healthcare systems are the prime conditions for the infection to spread, and thrive.
This ancient disease was known as the "White Plague" in 18th century Europe and still kills more than one million people a year globally.
Keertan Dheda, professor of medicine at the University of Cape Town It's a complicated disease with the potential to affect many parts of the body and it can remain latent in people for many years, leaving them unaware they are infected.
The main active form of the disease affects the lungs; if left untreated it can cause considerable lung damage, resulting in eventual death. Andile is one of thousands of people who contract the extensively drug-resistant form each year and he makes a crucial point -- TB is everywhere in South Africa and is the leading cause of death.
Hunting down 'fiery serpent' disease Looking at the disease globally, in there were 72 cases of drug-resistant TB in the United States. In there were 64, cases in India and 59, in China. The more people and the closer their proximity, the easier the disease spreads. Drug resistance can develop for a variety of reasons.
For TB, the origins lie in incomplete treatment regimens where people did not complete their course of antibiotics due either to poor health systems or personal preference or complacency. Incomplete treatments mean the bacteria behind the disease -- Mycobacterium tuberculosis -- have had some, but not full, exposure to the drugs prescribed to kill them, giving them the opportunity to mutate and become resistant.
The result today is such vast resistance that in some settings, all known drugs have been rendered useless and these forms are now transmitting between people. Global problem The problem is now global. Also firmly on the agenda was the global concern of antibiotic resistance and the fear of many diseases becoming untreatable.
The issue has been addressed by many public health organizations in and Heymann believes TB is a prime example of the problem and should be declared a public health emergency of international concern by the International Health Regulations Emergency Committee.
But such a declaration is yet to be made. This machine makes drinking water from thin air The man in charge of the controlling the problem globally is Mario Raviglione, director of the Global Tuberculosis Program at the WHO. Raviglione is especially concerned about the increased rates of drug-resistant TB seen in Southern Africa.A month after the Health Ministry set itself the target of eliminating tuberculosis (TB) by , a new study in the medical journal Lancet says that India’s TB crisis is likely to get worse.
Tuberculosis (TB) is an infectious disease usually caused by the bacterium Mycobacterium tuberculosis (MTB).
Tuberculosis generally affects the lungs, but can also affect other parts of the body. . The rise of drug-resistant TB is creating new challenges, especially for children, who are much more vulnerable to the disease and for whom the effects and side effects of treatment are greater.
