The World Health Organization has revised up its estimate of how many people have tuberculosis by almost 500,000.
In 2013 nine million people had developed TB around the world, up from 8.6 million in 2012, the WHO said.
However, the number of people dying from TB continued to decline, it added.
TB campaigners said that one of the biggest problems in tackling the deadly disease was gauging how many people were affected, BBC informs.
