The study, published in European Respiratory Journal, shows that one in four people in the world carries tuberculosis bacterium in the body.

Tuberculosis, which is caused by a bacterium called Mycobacterium Tuberculosis, affects more than 10 million people every year and kills up to two million, making it the most deadly of the infectious diseases.

Besides, several people are infected with the tuberculosis bacterium without having active disease called latent tuberculosis.

The study, which is based on tests from 351,811 individuals, emphasises that it will be extremely difficult to reach the WHO’s goal of eliminating tuberculosis by 2035.

The study indicates that somewhere between one-fifth and one-fourth of the population have latent tuberculosis.
