A kind of blood test that will be able to inform doctors well in advance if any individual is going to develop the mainstream tuberculosis is a step closer to becoming a reality.

Scientists are quite sure that they have finally been able to find a way that will capably be able to identify the 10% individuals infected with TB virus, who might go on developing the full-blown disease, from the 90% of healthy individuals who may have dormant kind of lung infectivity.

It clearly means that doctors could stream their concentration towards offering treatment to the one in ten infected individuals, who may run a high risk of falling extremely ill, and instead of trying to give potent anti-TB drugs to anyone exhibiting infection of TB virus.

Each year, no less than two million people pass away due to TB all through the world, but the disease is seen mostly in developing nations.

However, the disease seems to have entered many developed nations as well. In the year 2009, 9,153 cases had been recorded in Britain, which has been deemed as the largest annual increase ever since 2005, where nine out of ten cases occurred in the ethnic minority groups.
