Beijing - The World Health Organization (WHO) on Wednesday called for urgent action to halt an "alarming" rise in the spread of multi-drug resistant tuberculosis (MDR-TB).
"The situation is already alarming, and it is poised to grow much worse, very quickly," said WHO director-general Margaret Chan.
"If MDR-TB is not vigorously addressed, it stands to replace the mainly drug-susceptible strains currently responsible for 95 per cent of the world's TB cases," Chan said.
