The emergence of MDdR-TB and extensively drug-resistant TB (XDdR-TB) has raised special concerns in relation to the international spread of particularly dangerous strains of Mycobacterium tuberculosis. Since the 2006 edition was published, several incidents have occurred involving air travel and potential transmission of TB. The revision of the International Health Regulations (IHR), which entered into force in June 2007, provides for the introduction of new measures that might potentially apply to international events involving TB. The IHR provide a legal framework for a more effective and coordinated international response to public health emergencies and risks, including those caused by outbreaks of communicable diseases. Several IHR provisions are relevant to the detection and control of TB during air travel, strengthening the role of WHO and of national public health authorities in this domain. Following these important recent developments, WHO has prepared this third edition to address current public health risks that may arise from the potential transmission of TB during air travel, and new approaches to international collaboration. This edition builds upon the 2006 edition and adds to it in providing: (i) greater clarity in the definition of infectious index cases; (ii) procedures for the follow-up of contacts of infectious cases; and (iii) a more detailed definition of the roles and responsibilities of the agencies involved. The recommendations recognize that the response needs to be proportional to the risk, so that public confidence is preserved and unnecessary restrictions are avoided. The guidelines were developed with the collaboration of public health authorities and international experts in the prevention and control of TB, travel medicine and air travel. Implementing the recommendations will help to reduce the international spread of TB and decrease the risk of infection among individual travellers. Although the role of air travel-related transmission of TB is minimal compared with the overall transmission of TB worldwide, these guidelines may nevertheless be useful for national authorities, especially in countries with a low TB burden, and for the airline industry, to facilitate procedures involving multiple actors.In 2005, 5 million new and relapse TB cases were reported to WHO, of which 2.3 million were sputum smear-positive ... Several industrialized countries require medical examinations including TB screening for immigrants, refugees and asylumanbsp;...
