LECs should be conducted when there is evidence of large numbers of hidden cases. Probably a minimum of two LECs is required but where large number of new cases continue to be detected they could be run on an annual basis. The methodology of LECs needs to be improved through experience, evaluation and from LECs conducted elsewhere; feedback from the community is also important. There is room to improve all aspects of LECs: planning, training, education, diagnosis and treatment completion.</p>  a0305-7518
