[Tuberculosis and Tobacco Smoking]

Abstract

Worldwide there are annually about 9.6 million new cases and 1.5 million deaths due to tuberculosis (TB). Smoking is an independent risk factor causing approximately a twofold increase not only in active Tb disease but also in latent TB infection and mortality. In a mathematical model it is estimated that smoking would produce until 2050 an excess of 18 million tuberculosis cases from TB which would challenge the TB elimination goal of the WHO. Smoking cessation methods during and after TB treatment, which at present are insufficiently included into TB programmes, are urgently needed.
