Statistics

The global picture - the latest Stocktaking Report (2008) includes key statistics on progress that has been made in the following areas:

P1: Percentage of pregnant women living with HIV who received ARVs for PMTCT, 2004-2007

P2: Number of children under 15 receiving antiretroviral therapy in low- and middle-income countries (2005-2007)

P3: HIV prevalence among young people aged 15–24, 2007

P4: Percentage of orphans and other vulnerable children whose households received basic external support, 2005–2007

Note: The lines on the bars show the uncertainty bounds for the estimates. Data were insufficient to calculate an average for the Middle East and North Africa region. Source: UNICEF calculations based on data collected through the PMTCT and Paediatric HIV Care and Treatment Report Card process and reported in Towards Universal Access: Scaling up HIV services for women and children in the health sector – Progress Report 2008 (UNICEF, UNAIDS, WHO), pp. 19, 43. Regions were recalculated according to UNICEF classification of regions.

Coverage of services to prevent mother-to-child transmission of HIV is expanding. Still, in 2007, only 33 per cent of pregnant women living with HIV in low- and middle-income countries received antiretroviral regimens, including antiretroviral therapy to prevent transmission of the virus to their infants, compared to 10 per cent in 2004. Pregnant women infected with HIV need access to the best regimens possible for their own health, for the survival of their children and to prevent transmission of the virus to their infants. The goal is to offer appropriate services to 80 per cent of women in need by 2010.

Note: Regional totals do not add up to the total for low- and middle-income countries because of rounding. The seven 'hyper-endemic' countries are all in the Eastern and Southern Africa Region.Source: UNICEF calculations based on data collected through the PMTCT and Paediatric HIV Care and Treatment Report Card process and reported in Towards Universal Access: Scaling up HIV services for women and children in the health sector – Progress Report 2008 (UNICEF, UNAIDS, WHO), pp. 34–42. Regions were recalculated according to UNICEF classification of regions.

The most recent global estimates indicate that more than 2 million children under the age of 15 are living with HIV – the vast majority of them in sub-Saharan Africa. Yet only around 198,000 children under 15 in low- and middle-income countries received life-saving antiretroviral treatment in 2007. Coverage will need to be greatly expanded if the international target of providing antiretroviral treatment, cotrimoxazole or both to 80 per cent of children in need by 2010 is to be met.

Girls and young women remain disproportionately vulnerable to HIV infection in sub-Saharan Africa, particularly in the hyper-endemic countries, where prevalence is greater than 15 per cent. Addressing the vulnerability of girls is a priority focus of key development partners, including the Global Fund to Fight AIDS, Tuberculosis and Malaria and UNAIDS. The United Nations has established the goal of reducing the percentage of young people living with HIV by 25 per cent by 2010.

There is growing consensus among most practitioners and policymakers that responses to children made vulnerable by HIV and AIDS should be AIDS-sensitive – but not AIDS-exclusive – and that a focus should be on strengthening social protection systems. But the process of developing national plans of action for orphans and vulnerable children has generally been slow. Of 18 countries surveyed between 2005 and 2007, the proportion of orphans and vulnerable children whose households received basic external support ranged between 1 per cent in Sierra Leone and 41 per cent in Swaziland, with a median value of 12 per cent. The goal is to reach 80 per cent of the children most in need by 2010.

Available statistics related to HIV/AIDS for every country and territory of the world are published annually in UNICEF's flagship publication, The State of the World's Children, and the UNAIDS flagship publication which is the Report on The Global AIDS Epidemic and the AIDS Epidemic Update. You can access these from the 'By country' link on the left.

The 'Global statistics' link, also left, provides a snapshot of the key global HIV/AIDS statistics including HIV infections, mother-to-child transmission and deaths.

Childinfo.org
You can access UNICEF's key statistical databases with detailed country-specific information that was used in the end-decade assessment of progress and setbacks in implementing the 1990 World Summit for Children Declaration and Plan of Action on ChildInfo. The site contains global and regional summary analyses and graphics of key results, in addition to new and revised data.

HIV/AIDS Survey Indicators Database
The HIV/AIDS Survey Indicators Database provides an easily accessible comprehensive source of information on HIV/AIDS indicators derived from sample surveys. The database allows the user to produce tables for specific countries by select background characteristics, as well as country reports.

Epidemological Fact sheets
The Epidemiological Fact Sheets contain current available information on the HIV/AIDS epidemic by country. The sheets have a wide variety of information including: estimates of number of people living with HIV/AIDS, HIV prevalence in different populations, estimated size of populations at increased risk to HIV, maps of HIV sentinel sites, data on sexually transmitted infections, demographic and socio-economic data, knowledge and behavioral data, health service and care indicators, and prevention indicators.

HIV/AIDS Surveillance Data Base
Information on the AIDS pandemic and on the HIV seroprevalence (infection) in population groups in developing countries is only available in widely scattered small-scale surveys. The HIV/AIDS Surveillance Data Base was developed and is maintained by the Health Studies Branch, International Programs Center (IPC), Population Division, U.S. Bureau of the Census, with funds from the U.S. Agency for International Development. It is a compilation of information from those studies appearing in the medical and scientific literature, presented at international conferences, and appearing in the press. The data base was developed on the microcomputer for portability and has a user-friendly interface. Available information for population groups in a selected country can be easily retrieved and displayed on the computer screen, printed in tabular format, or saved to an ASCII or Lotus file.

The data base is updated twice a year. The International Programs Center welcomes comments and suggestions from users of the data base. IPC also welcomes copies of articles or references to information which may have been overlooked.

UNAIDS/WHO Global HIV/AIDS Online Database
This database collates the most recent country-specific data on the spread and impact of the virus, together with information on risk behaviours (e.g. casual sex and condom use). Health sector response information (eg. data on people receiving treatment and coverage of HIV counselling and testing) is also an essential part of this database.
