Statistical concept and methodologyMethodology: UNAIDS produces annual HIV/AIDS-related indicators using a common modelling framework (Spectrum). The model integrates country-reported data on HIV surveillance, antiretroviral therapy (ART) coverage, demographic information, and established patterns of HIV transmission, disease progression, and survival. Because many countries lack complete case reporting or cause-of-death data, these figures are modelled estimates and include uncertainty ranges. UNAIDS updates the estimates each year as new data and methods become available, ensuring internal consistency across all HIV/AIDS-related indicators.

Development relevanceDespite the existence of effective medications and treatment, HIV/AIDS is still a leading cause of death and public health threat in the world. Low and middle income countries continue to bear a disproportionate share of the global burden of HIV/AIDS. The incidence rate provides a measure of progress toward preventing onward transmission of HIV. Also, the identification of newly infected persons will allow for interventions to reduce the risk of HIV transmission.
