Five million people infected by HIV this year
The 4.9 million new infections were fuelled by the epidemic's continuing rampage in sub-Saharan Africa and a spike in the former Soviet Union and Eastern Europe, the UNAIDS body said in its annual report.
"Despite progress made in a small but growing number of countries, the AIDS epidemic continues to outstrip global efforts to contain it," the report said.
More than 3.1 million people have died this year from AIDS, including 570,000 children - far more than the toll from all natural disasters since last December's tsunami.
Southern Africa, including South Africa - which has the world's most cases at more than 5.1 million - continues to be worst-hit.
Saying nine out of 10 people in developing countries do not know their HIV status, UNAIDS Executive Director Peter Piot called for an unprecedented response to the AIDS crisis.
"A business-as-usual approach will not do," he told a news conference in New Delhi. India has about 5 million HIV sufferers and there are concerns many cases are unreported.
Focusing on South Africa, where the infection rate among pregnant women touched 29.5% in 2005, the report said deaths of people aged between 25 and 44 had more than doubled.
Other southern Africa countries such as Botswana, Lesotho, Namibia and Swaziland had rates of more than 30% of HIV among pregnant women.
Sub-Saharan Africa is home to 25.8 million HIV-positive people, or 64% of the world's total.
In Asia,1.2 million new cases since 2003 pushed total cases to 8.3 million, with conditions in countries such as Vietnam and Pakistan ripe for a rapid spread.
UNAIDS said the number of HIV-positive women reached 17.5 million this year, more than one million more than in 2003.
"In many countries, marriage and women's own fidelity are not enough to protect them against HIV infection," the report said, adding in India many new infections were being reported in married women infected by their husbands after visiting sex workers.
In Eastern Europe, Central Asia and the Russian Federation, infections due to unprotected sex are rising after the initial momentum given to the epidemic by injecting drug use.
The report said 1.6 million were living with HIV in 2005 in the region, up from 1.3 million in 2003, and AIDS deaths soared to 62,000 in 2005 from 36,000 in 2003.
Mr Piot slammed the response in a region which has seen the number of infections rise 20-fold in a decade.
"The response has been fragile and insufficient," he said.
But he said world leaders across were far more aware of the crisis and spending to combat AIDS had touched $8 billion (€6.8bn) this year compared with $250 million (€213m) in 1996.
Executive director of leading Indian HIV group the Naaz Foundation, Anjali Gopalan, said: "UNAIDS and governments should wake up and smell and the coffee.
"If there is so much money, why can't we combat the disease? Why is there such a desperate situation? UNAIDS and governments must be made more accountable about where the money is going."
The outlook on accessibility of anti-retroviral drugs for people in developing nations is looking brighter, the UN said.
"Because of recent treatment scale-up since the end of 2003, between 250,000 and 350,000 deaths were averted in 2005."
But it added too many HIV-positive people were missing out, with just one-in-10 Africans and one-in-seven Asians who need anti-retroviral treatment actually receiving it.
Two decades into the HIV/AIDS epidemic, the report said that in many parts of the world knowledge about HIV transmission was alarmingly low.
The chief of India's National Aids Control Organisation, SY Quraishi, said 70% of Indian sex workers either did not know what a condom was or how to use one.
He said: "If the situation remains unchanged, India could have 50 million HIV cases by 2025."
