Tuberculosis and HIV
The risk of developing tuberculosis (TB) is estimated to be between 20-37 times greater in people living with HIV than among those without HIV infection. In 2010, there were 8.8 million new cases of TB, of which 1.1 million were among people living with HIV. In response to demands from countries, WHO recommends 12 TB/HIV collaborative activities, including the Three I's for TB/HIV. The WHO HIV/AIDS and TB Departments and their partners, including community groups, work collaboratively on joint TB/HIV advocacy, policy development and implementation in countries.
