Tuberculosis is increasing in incidence in many large cities in the UK. This contrasts with stable or declining rates in most western European countries. Ibrahim Abubakar and colleagues explain why and describe what needs to be done to regain control

Easy travel and migration have allowed tuberculosis to re-emerge as a public health problem in many European countries.1 In the United Kingdom the number of reported cases is now at its highest since the 1970s. In 2009, 9040 cases of active tuberculosis were notified, which represents roughly a 75% increase over the past 20 years.2 Most cases occur in large towns and cities (fig 1). We present an analysis of the size of the problem, factors driving the epidemic, weakness of our current control strategies, lessons to be learnt from other tuberculosis control programmes, and the actions required to achieve tuberculosis control in the UK.

Who has tuberculosis in the UK?

Most cases of tuberculosis (73% in 2009) in the UK occur in people born outside the country (fig 2, table 1).3 The majority develop active symptomatic disease several years after arrival (in 2009, almost four fifths had lived in the UK for two or more years). DNA fingerprinting studies suggest that most cases arose from latent Mycobacterium tuberculosis infection acquired outside the UK.4 This forms a reservoir of latent M tuberculosis infection from which future cases may arise.
