The National Centre for Tuberculosis and Leprosy Control at the Ministry Health announced Thursday that tuberculosis cases jumped by nearly 1,000 in 2009 compared with 2008. But Mao Taing Eang, director of the centre, said at a conference Thursday that despite the rise in confirmed cases, the prevalence of the disease was actually falling. The increase, he said, is a result of Directly Observed Therapy (DOT) services to communities that are detecting the disease faster. “We will continue to add more DOT’s to communities in 2010, especially in communities where epidemics are occurring,” he said.
