London,Mar 16: Multi-drug resistant tuberculosis poses a major threat to the European Union, a World Health Organization report says. Researchers found rates of MDR-TB are very high in several former Soviet republics. China is another blackspot. The report estimates there are 300,000 cases world-wide - and warns that no country is safe. It says increased funding for TB treatment programmes in badly affected areas is the only effective way to tackle the problem. Attempts to contain the disease by beefing up border controls are unlikely to have much effect in an era of mass population movement. Bureau Report
