ETW 2022: Updated definition of HIV late diagnosis

Time: Monday 21 Nov 2022, 15:30-16:30 CET

Background: HIV testing frequency has increased in many settings, resulting in more people being diagnosed during seroconversion with a temporarily low CD4 count. Using the current consensus definition of late HIV diagnosis (CD4 count <350 cells/µl or an AIDS-defining event), these individuals will be incorrectly assigned as being diagnosed late. A European expert group, convened under the EuroTEST Initiative, reviewed and revised the current definition and conducted a survey in the WHO European Region countries on the availability of data to apply this revised definition.

Aim: To learn about the revised definition and its implication for data collection, reporting and surveillance

Target group: HIV clinicians, public health experts, epidemiologists and surveillance experts, community members.
