Tuberculosis and HIV
The risk of developing tuberculosis (TB) is estimated to be between 12-20 times greater in people living with HIV than among those without HIV infection. In 2011, there were 8.7 million new cases of TB, of which 1.1 million were among people living with HIV. WHO recommends 12 TB/HIV collaborative activities, including the Three I's for TB/HIV. The WHO HIV and TB Departments and their partners, including community groups, work collaboratively on joint TB/HIV advocacy, policy development and implementation in countries. WHO develops and promotes tools and guidelines to support countries in improving their TB/HIV collaborative action in order to achieve universal access to HIV and TB prevention, care and treatment services for all people in need.
