HIV/AIDS

Introduction:

With a view to facilitating the scaling up of access to antiretroviral therapy, and in line with a public health approach, this publication outlines recent revisions WHO has made to case definitions for surveillance of HIV and the clinical and the immunological classification for HIV related disease. HIV case definitions are defined and harmonized with the clinical staging and immunological classifications to facilitate improved HIV-related surveillance, to better track the incidence, prevalence and treatment burden of HIV infection and to plan appropriate public health responses.
