Africa: Global efforts to control TB not working?

Global efforts to control rising levels of tuberculosis are not working and more needs to be done to reduce infections from the deadly airborne disease, public health experts said on Tuesday. The World Health Organization (WHO) introduced a strategy in 1993 aimed at halving deaths over the next decade from the contagious illness that kills about 2 million people each year. But researchers at Harvard University in the United States said a decade after the DOTS (Directly Observed Treatment, Short-course) plan was introduced, the global burden of TB continues to rise.
