Concepts

Cluster of differentiation 4 (CD4) cell count is a laboratory test that measures the number of CD4 T-cells in the body. This is used to monitor the destruction of CD4 cells that is caused by HIV (the lower the CD4 cell count, the more advanced the stage of HIV) and also can measure the effectiveness of anti-retroviral treatment.
Refer to SDG global metadata for more information.

Computational Method

4 sets of data on the CD4 cell count, differentiated by data range, are used for input to a staged back-calculation modelling tool. The tool used is the European Centre for Disease Prevention and Control (ECDC) HIV modelling tool.
