ReacciónThe recommendations and the text of the WHO consolidated guidelines on tuberculosis. Module 1: Prevention – tuberculosis preventive treatment, second edition are the result of collaboration among professionals in various specialties with extensive expertise and experience in public health policy, tuberculosis (TB) programme management and the clinical care of TB patients. The recommendations in these guidelines were developed by successive guideline development groups (GDGs) convened by WHO, the latest of which met in December 2023. WHO gratefully acknowledges the contributions of all experts involved in preparation of these guidelines.¹
The production and writing of these guidelines were coordinated by Avinash Kanchar, Dennis Falzon, Saskia den Boon and Matteo Zignol under the overall direction of Tereza Kasaeva, Director of the WHO Global Tuberculosis Programme.
