New Metrics to Monitor and Evaluate the Impact of Antiretroviral Treatment
Antiretroviral therapy (ART) prevents both the progression of HIV disease and the transmission of the virus. The more people living with HIV know their status, are linked to care and take ART and do not have detectable HIV the less likely they transmit HIV.
Simple metrics can help policy makers and programme planners to evaluate the prevention benefit of their ART programmes. Such metrics can also provide useful information to care providers on improving HIV services.
The WHO Regional Offices for the Western Pacific and South-East Asia are releasing simple Metrics for Monitoring the Cascade of HIV Testing, Care and Treatment Services in Asia and the Pacific together with the Centers for Disease Control and Prevention, and the United States Agency for International Aid, The U.S. President's Emergency Plan for AIDS Relief.
