Understanding and Using Tuberculosis DataUnderstanding and Using Tuberculosis Data cover



Country health information systems provide a rich source of data on the burden of disease caused by tuberculosis (TB) and the effectiveness of programmatic efforts to reduce this burden, both of which are crucial for public health action.



Use of Bedaquiline in the Treatment of Multidrug-resistant TuberculosisUse of Bedaquiline in the Treatment of Multidrug-resistant Tuberculosis cover




The emergence of drug resistance is a major threat to global tuberculosis (TB) care and control. The World Health Organization (WHO) estimates that up to half a million new cases of multidrug-resistant tuberculosis (MDR-TB) cases (i.e. resistant to, at least, rifampicin and isoniazid) occur each year globally.


Systematic Screening for Active TuberculosisSystematic Screening for Active Tuberculosis cover

Recommendations for Investigating Contacts of Persons with Infectious Tuberculosis in Low- and middle-income CountriesRecommendations for Investigating Contacts of Persons with Infectious Tuberculosis in Low- and middle-income Countries cover



Tuberculosis (TB) contacts are people who have close contact with patients with infectious TB. As they are at high risk for infection (and in line with the Stop TB strategy), TB contacts should be investigated systematically and actively for TB infection and disease. Such interventions are called 'tuberculosis contact investigations'.
