The number of new infections is important for monitoring both epidemic trends and dynamics within the population.
Definition:
The estimated annual number new HIV infections estimated by the end of a specific year.
Disaggregation:
Age, Sex
Method of measurement
Analysis of country data on HIV prevalence, particularly among young age groups and, where available, direct HIV incidence data; internationally consistent modelled estimates, e.g. Spectrum AIM.
M&E Framework:
Impact
Method of estimation:
Modelled estimates of the number of new HIV infections are produced and compiled by country teams and published annually by UNAIDS and WHO. Standard methods and tools for HIV estimates that are appropriate to the pattern of the HIV epidemic are used . However, to obtain the best possible estimates, judgment needs to be used as to the quality of the data and how representative it is of the population.
