WHO consolidated guidelines on tuberculosis Module 2: Screening – Systematic screening for tuberculosis disease


In view of these new developments and upon demand by countries for more guidance, WHO convened a Guideline Development Group (GDG) in 2020 to examine the evidence and prepare WHO consolidated guidelines on tuberculosis. Module 2: Screening - Systematic screening for tuberculosis disease. As a result of this process a set of 17 new and updated recommendations for the screening of TB disease have been developed. These recommendations identify contacts of TB patients, people living with HIV, people exposed to silica, prisoners and other key populations to be prioritized for TB screening. The new guidance also recommends different tools for screening, namely symptom screening, chest radiography, computer-aided detection software, molecular WHO-approved rapid diagnostic tests, and C-reactive protein. The new recommendations are being released as part of a modular series of WHO guidance on TB and are accompanied by a complementary implementation guide.
