A growing "workforce crisis" is a serious obstacle to achieving targets for global tuberculosis control set for 2005 by the World Health Organisation (WHO). Faster and more effective recruitment and training of TB health workers is needed to ensure vacancies in developing countries are filled quickly, says a draft report written by TB experts. Of the 22 high burden countries (HBCs) which account for 80% of the world's TB cases, 17 reported that their efforts to reach the 2005 targets are being hampered by staffing problems.
