According to UNAIDS, the AIDS epidemic claimed an estimated 2.8 million (between 2.4 and 3.3 million) lives in 2005 of which more than half a million (570,000) were children.
It should however be noted that this is only an estimate. And that obtaining accurate figures is complicated by several factors:
- People do not die of AIDS as such - they die of the diseases that AIDS has made them vulnerable to. Therefore, the cause of death is very often not given as AIDS or AIDS-related.
- Diagnosing a death as AIDS related relies on the person having been diagnosed as HIV-positive .. a diagnosis that has often not been made in a resource-limited setting.
- With advances in medicine, AIDS is "greying". Instead of dieing from AIDS-related conditions, people who were living with AIDS are increasingly dieing of old age.
- In order to spare the feelings of relatives (and to protect them from the stigma of being associated with AIDS) official causes of death are frequently recorded in a vague manner.
