About a quarter of the world’s population is estimated to be infected with Mycobacterium tuberculosis bacilli, most of whom are not sick or infectious. Although they are well, people who are infected may develop TB disease in the future. Treating people infected with TB bacilli reduces the risk of TB infection progressing to active TB disease. 
This e-learning course will provide the knowledge and skills necessary to support staff in countries in scaling-up targeted TB preventive treatment in their national TB strategy or supporting staff who seek guidance on implementation.
The main focus of this e-course is programmatic; clinical aspects are only discussed when relevant to specific topics.
