Geneva, Ramadan 6, 1435, Jul 3, 2014, SPA -- The World Health Organization (WHO) on Thursday urged over 30 countries, including some of the world's richest, to recognize the continued danger of tuberculosis and try to wipe it out by 2050. TB claimed 1.3 million lives worldwide last year, making it the deadliest disease after AIDS to be caused by a single infectious agent, according to WHO. "We are at an historical point now in control of tuberculosis worldwide and there are number of countries, we count 33, that are really at the low level of incidence that allows them to truly target elimination," Marco Raviglione, head of the WHO's anti-TB programme, told reporters. --SPA 20:51 LOCAL TIME 17:51 GMT www.spa.gov.sa/w
