Tuberculosis and HIV infection: the global setting.

Tuberculosis (TB) and human immunodeficiency virus (HIV) infection make each other's control significantly more difficult. Coordination in addressing this "cursed duet" is insufficient at both global and national levels. However, global policy for TB/HIV coordination has been set, and there is consensus around this policy from both the TB and HIV control communities. The policy aims to provide all necessary care for the prevention and management of HIV-associated TB, but its implementation is hindered by real technical difficulties and shortages of resources. All major global-level institutions involved in HIV care and prevention must include TB control as part of their corporate policy. Country-level decision makers need to work together to expand both TB and HIV services, and civil society and community representatives need to hold those responsible accountable for their delivery. The TB and HIV communities should join forces to address the health-sector weaknesses that confront them both.
