Annex 2.
HIV/AIDS estimates and data, end 1999
The estimates and data provided in the following table relate to the end of 1999
unless stated otherwise. They are given in rounded numbers. However, unrounded.
numbers were used in the calculation of rates and regional totals, so there may be
small discrepancies between the regional/global totals and the sum of the country
figures.
Adults in this report are defined as men and women aged 15-49. This age range
captures those in their most sexually active years. While the risk of HIV infection
obviously continues beyond 50, the vast majority of those with substantial risk
behaviour are likely to have become infected by this age. Since population structures differ greatly from one country to another, especially for children and the upper
adult ages, the restriction of "adults" to 15-49-year-olds has the advantage of making different populations more comparable. This age range was used as the denominator in calculating the adult HIV prevalence rate.
The methodology used to produce the country-specific estimates in the table has
been described in full elsewhere (Schwartlinder et al. AIDS 1999; 13:2445-2458).
Notes on specific indicators listed in the table
A/
1. People living with HIV/AIDS, end 1999
These estimates include all people with HIV infection, whether or not they have
developed symptoms of AIDS, alive at the end of 1999.
For country estimates marked with an asterisk, not enough data were available to produce an estimate of HIV prevalence for end 1999. For each of these countries the 1994
prevalence rate published by the WHO Global Programme on AIDS (Weekly epidemiological record 1995; 70:353-360) was applied to the country's 1999 adult population
to produce the estimates given in the table. No country-specific models were produced for countries marked with an asterisk. For data columns containing few or no
country estimates, the regional totals were calculated on the basis of a regional model.
