With nearly one thousand infected 620, Brazil has the largest population of HIV positive in Latin America, as the report says, by population size. As in recent years, the UN praises Brazil's program to combat the disease.
In sub-Saharan Africa, the region most affected by the disease worldwide, the proportion of people with AIDS has, in most countries, although it remained stable, according to UNAIDS, this happens at the expense of the high mortality of those infected.
"This apparent stabilization of the epidemic reflects situations where the numbers of people being infected with HIV is almost equivalent to the numbers of people dying from AIDS-related illnesses," the report warns.
"A little more than a tenth of the world population lives in sub-Saharan Africa, home to almost 64% of all people living with HIV - 24,5 million. Two million of them are children younger than 15 years. "
Also according to the report, about 930 thousand adults and children died of AIDS in South Africa in 2005 - which represents a third of all deaths from the disease last year.
But the UN also highlights the exceptions of Kenya, Zimbabwe and urban areas of Burkina Faso, where the disease has been decreasing.
Another case of decline highlighted in the report is that of Angola, where the isolation caused by 27 years of civil war have somewhat contained HIV transmission.

In the case of the Russians, however, the number of new diagnoses confirming the presence of HIV is stabilizing. Other countries where the disease is spreading more are Kazakhstan, Tajikistan and Uzbekistan.
