World Health Organization (WHO) officials recently urged Asia-Pacific governments to shake off complacency and intensify the fight against tuberculosis (TB), which kills 1,000 people a day in the region. Shigeru Omi, regional director of WHO for the Western Pacific, said deaths caused by tuberculosis continue to rise in the region as ’more and more people are infected with the dreadful disease every year.
"Every year, an additional two million tuberculosis cases are diagnosed in the region," Omi said at a news conference during the opening of a two-day meeting of Asian’ parliamentarians to discuss strategies to control the disease.

(44) It noted that more that 40 million people are infected with the disease and "10 percent of them -will develop TB in their lifetime. "In Cambodia, more than 7 million people, or 60 percent of the population, are infected with the disease, while in Vietnam more than 145, 000 people are infected each year. "In several developed and newly industrialized countries in the Western Pacific region, TB prevalence has not decreased markedly during the last decade although economic growth should make more resources available to deal with the problem, "WHO said.
