Beijing (BBC): China has more than halved its tuberculosis (TB) prevalence, with rates falling from 170 to 59 per 100,000 population, figures suggest. The Lancet report says the success is due to a huge expansion of a community-based disease control programme. The World Health Organization says other countries could use a similar approach. China is a major contributor to the global TB pandemic, accounting for more than one-tenth of cases worldwide.
