Current status + progress
Progress in reducing new HIV infections among children has stagnated in recent years
- About 160,000 [Confidence bounds: 100,000-240,000] new HIV infections among children under 5 years of age occurred in 2020, dramatically declining from 320,000 [210,000-500,000] in 2010 and representing a 52 per cent decline.
- Among the 35 UNICEF HIV priority countries, about 120,000 [80,000-200,000] new HIV infections among children under 5 years of age occurred in 2020 from 290,000 [210,000-500,000] in 2010, representing a 57 per cent decline.
Progress in reducing mother-to-child transmission of HIV has been dramatic since the introduction in 2011 of the ‘Global Plan towards the Elimination of New HIV Infections among Children and Keeping their Mothers Alive’ – largely because of increased access to prevention of mother- to-child transmission (PMTCT) related services and an increased number of pregnant women living with HIV being initiated on lifelong antiretroviral medicines. But it was not fast enough to reach the 2020 targets set by UNAIDS and partners as part of the Super-Fast-Track Framework to end AIDS. Acceleration of treatment for all pregnant and breastfeeding women living with HIV is still needed to achieve elimination of new infections among children and halve HIV-related deaths among pregnant women and new mothers.
Data sources + methodology
Global AIDS monitoring 2020
In order to monitor the HIV response and progress towards achieving global goals, countries submit national and subnational data on a host of indicators to the Global AIDS Monitoring (GAM) system. Annual submissions are reviewed and validated. Data consist of programmatic data for HIV prevention, testing and treatment. Other indicators require data from population-based surveys and surveys focused on key populations at risk of HIV infection.

UNAIDS Estimates and Spectrum’s AIDS Impact Model
Each year countries update their AIDS Impact Model in Avenir Health’s Spectrum software to develop the latest estimates for the HIV epidemic. Supported by UNAIDS, WHO and UNICEF these estimates are used to inform programme and policy decisions for HIV epidemic response.
Methods for HIV modelling are developed by the UNAIDS Reference Group on Estimates, Modelling and Projections.
All available data on HIV estimates are available at aidsinfo.unaids.org.
Nationally representative surveys
Multiple Indicator Cluster Surveys (MICS), Demographic and Health Surveys (DHS), AIDS Indicator Surveys (AIS), Population-based HIV Impact Assessments (PHIA) reproductive health surveys, sexual behaviour surveys and other nationally representative surveys are currently used to collect data on HIV and AIDS.
