Story said guidelines from the National Institute for Clinical Excellence [http://guidance.nice.org.uk/CG33/guidance/pdf/English] and the Department of Health’s Health Clearance for new Health Care Workers and Policy and Guidance Green Book were”slightly conflicting and by no means simple”, but there were “some reassuring messages” about the level of risk.
TB rates have increased annually nationally since 1987 and rose by 11% to 8,113 case between 2004 and 2005, with 43% in London. The causes include deprivation, delays in presentation and treatment, drug resistance (the last new drug was launched in in 1963), drug abuse, the high prison population and homelessness.
