Outbreak column 21: Tuberculosis (TB): Still a nosocomial threat

摘要

This outbreak column explores the epidemiology and infection prevention guidance on tuberculosis (TB) in the UK.The column finds that, at present, national guidance leaves UK hospitals ill-prepared to prevent nosocomial TB transmission. Reasons for this conclusion are as follows: (I) while TB is predominantly a disease that affects people with 'social ills', it has the potential to infect anyone who is sufficiently exposed; (2) nosocomial transmission is documented throughout history; (3) future nosocomial exposures may involve less treatable disease; and (4) current UK guidance is insufficient to prevent nosocomial transmission and is less than that advocated by the World Health Organization and the Centers for Disease Control and Prevention.
