- Goal
Goal 3: Ensure healthy lives and promote well-being for all at all ages
- Target
Target 3.3: By 2030, end the epidemics of AIDS, tuberculosis, malaria and neglected tropical diseases and combat hepatitis, water-borne diseases and other communicable diseases
- Indicator
Indicator 3.3.1: Number of new HIV infections per 1,000 uninfected population, by sex, age and key populations
- Series
Not applicable
- Related indicators
Achieving this target will positively impact multiple SDG goals and by reaching other goals will improve countries ability to reduce new HIV infections. The goals that are linked to HIV include goals 1 through 8, 10, 11, 16 and 17.

Data sources | Not available for this indicator |
Spectrum modelling is used for the data presented here which incorporates programme data, surveillance data, survey data and region-specific assumptions about the HIV epidemic. Alternative methods of measures include household or key population surveys with HIV incidence-testing, or routine surveillance among key populations. The model development is guided by the UNAIDS Reference Group on Estimates, Modelling and Projections provides technical guidance on the development of the HIV component of the Spectrum software (www.epidem.org). The Spectrum software is developed by Avenir Health (www.avenirhealth.org)—which includes a module, the Estimates and Projections Package, which is developed by the East-West Center (www.eastwestcenter.org). |
Data collection method | Not available for this indicator |
Country teams use UNAIDS-supported Spectrum software to develop estimates annually. The country teams are comprised primarily of national epidemiologists, demographers, monitoring and evaluation specialists and technical partners. The model incorporates data that are collected through programme information systems, surveillance and surveys. |
Data collection calendar | Not available for this indicator |
Data sources are compiled all year long. The spectrum models are created in the first three months of every year and finalized by May. |
Data release calendar | Not available for this indicator |
Data are released every year in July |
Data providers | Not available for this indicator |
The estimates are produced by a team of national experts consisting of ministry of health, national AIDS advisory groups and development partners. The results are signed off on by senior managers at the ministries of health. |
Data compilers | Not available for this indicator |
After the data review process, the national experts share their results with UNAIDS who compiles the data for all countries and calculates regional and global estimates. |
Institutional mandate | Not available for this indicator |
The UN Political Declarations on HIV/AIDS (from 2001, 2011, 2016 and 2021) have mandated for UNAIDS to support countries to produce these data and for UNAIDS to report on the status of the Global HIV epidemic annually as well as through the UN Secretary General. |

Rationale | Not available for this indicator |
The incidence rate provides a measure of progress toward preventing onward transmission of HIV. Although other indicators are also very important to the HIV epidemic, HIV incidence reflects success in prevention programmes and, to some extent, successful treatment programmes, as those will also lead to lower HIV incidence. |
Comments and limitations | Not available for this indicator |
The methods and limitations for estimating HIV incidence vary based on the data and surveillance systems available in countries.
|
Method of computation | Not available for this indicator |
Longitudinal data on individuals newly infected with HIV would be the most accurate source of data to measure HIV incidence, however these data are rarely available for representative populations. Special diagnostic tests in surveys or from health facilities can also be used to obtain data on HIV incidence but these require very large samples to accurately estimate HIV incidence and the latter are also rarely representative. HIV incidence is thus modelled using the Spectrum software. The software incorporates data on HIV prevalence, the number of people on treatment, demographics and other relevant indicators to estimate historical HIV incidence, among other indicators. A full description of the model is available in peer-reviewed articles and in the most recent UNAIDS Global AIDS Update Reports. https://onlinelibrary.wiley.com/toc/17582652/2021/24/S5 https://www.unaids.org/en/resources/documents/2021/2021-global-aids-update |
Adjustments | Not available for this indicator |
No adjustments are made to the estimates. |
Treatment of missing values (i) at country level and (ii) at regional level | Not available for this indicator |
• At country level: Estimates are not collected from countries with populations < 250,000 according to the latest world population prospects estimates. In addition no estimates are available for 8 countries with very small HIV epidemics who do not produce estimates. For some countries in which the estimates were not finalized at the time of publication the country-specific values are not presented .
• At regional and global levels: The countries with populations < 250,000 and the 8 countries that do not produce estimates are not included in regional or global level estimates. For countries in which the estimates were not finalized at the time of publication, the unofficial best estimates are included in the regional and global values. |
Regional aggregations | Not available for this indicator |
Available for the World, the SDG regional groupings, Least Developed Countries, Landlocked Developing Countries and Small Island Developing States. |
Methods and guidance available to countries for the compilation of the data at the national level | Not available for this indicator |
A description of the methodology is available from the latest Global AIDS Update reports in the methods annex. Resources are also available at HIVtools.unaids.org. Countries are provided with capacity building workshops on the methods every other year. In addition, they are supported by in-country UNAIDS advisers in roughly 45 countries. Where no in-country specialists are available, remote assistance is provided. Training videos and documentation are also available at: HIVtools.unaids.org
|
Quality management | Not available for this indicator |
Development of methods is overseen by an external reference group of experts (www.epidem.org). The actual files are reviewed by UNAIDS global experts to ensure consistency between countries. |
Quality assurance | Not available for this indicator |
Countries are fully involved in the development of the estimates. The final values are reviewed for quality by UNAIDS and approved by senior managers at national Ministries of Health. |
Quality assessment | Not available for this indicator |
Results are routinely compared to empirical evidence when available. These empirical data include research studies, household surveys with incidence measurement, and longitudinal HIV surveillance sites when available. If inconsistencies are found modifications are considered for the models. Methods are also published in peer-reviewed journals every two years. See links to publications at www.epidem.org |
