Note regarding behavioural data published in the 2007 AIDS Epidemic Update

Immediately after the 2007 AIDS Epidemic Update was released electronically on 20 November 2007 some problems were discovered with data processing in relation to the behavioural data among young people, reported in Table 3 on page 13.
Following verification, corrections were made to the data for several countries in this Table.
The data that appear in the electronic version as of 26 November 2007 and in the printed version of the 2007 AIDS Epidemic Update therefore contain the corrected data.


Erratum regarding estimates among children

In-depth review of HIV estimates among children published in the 2007 AIDS Epidemic Update report in November 2007 has revealed inaccuracies in processing some of the data.
The correct provisional global estimates for 2007 are:
Number of children living with HIV in 2007: 2.1 million [1.9-2.4 million];
Number of children who died of AIDS in 2007: 290,000 [270 000-320 000].
Note that adding these corrected estimates for children to the estimates for adults does not add up to the published estimated total number of people living with HIV of 33.2 million [30.6–36.1 million] and of people who died of AIDS of 2.1 million [1.9–2.4 million], although the estimated ranges are not affected.
Updating estimates is a continuous process and work is ongoing to produce estimates for adults and children for all individual countries. Final country, regional, and global estimates for 2007 will be published in the 2008 Report on the global AIDS epidemic, during July 2008.
