GENEVA, Nov 21 (Reuters) - HIV infection is rising in every region of the world and most worryingly in countries like Uganda and Thailand, which had been heralded as success stories in the fight against AIDS, the United Nations said on Tuesday.
Nearly 40 million adults and children are infected worldwide. The most striking increases in new cases are in east Asia and in eastern Europe/central Asia, mainly due to drug use and unsafe sex, UNAIDS and the World Health Organisation said.
Somebody is infected with the HIV virus every 8 seconds, equivalent to 11,000 infections worldwide every day, while another 8,000 infected people die, the two agencies said in a joint annual report "2006 AIDS Epidemic Update".
"Evidence shows again that the global epidemic is growing in all areas," Peter Piot, executive director of UNAIDS, told a news conference.
"Perhaps of even greater concern to me is the fact that in some countries that had known real results in the fight against AIDS -- Uganda and some western countries -- we see an increase in infection rates."
Some 4.3 million people across the globe became infected with HIV this year, with a heavy concentration among young people, bringing the total number to an estimated 39.5 million.
Sub-Saharan Africa, which recorded 2.8 million new infections, still bears the brunt of the AIDS scourge, with 24.7 million people living with HIV, according to the report.
Of the 2.9 million global deaths from AIDS last year -- which Piot said was the highest number recorded -- 2.1 million occurred in Africa, the core area of the 25-year-old epidemic.
China's drug-fuelled HIV epidemic, which accounts for about half the country's estimated 650,000 infections, has reached "alarming proportions", according to the report.
"With HIV spreading gradually from most-at-risk populations to the general population, the number of HIV infections in women is growing too," it said of China.
PAST SUCCESS STORIES
Uganda is among countries suffering a resurgence of infection rates which were previously stable or declining.
New data showed erratic condom use in Uganda and more men having sex with more than one partner, as well as evidence of rising HIV prevalence in some rural areas, according to Karen Stanecki, UNAIDS senior epidemiologist.
"In Thailand, another one of our past success stories, the number of new infections continues to drop but the epidemic is changing and countries such as Thailand and Uganda need to take into account the fact that epidemics do change over time," Stanecki said.
In Thailand, a large percentage of new HIV infections occur in people considered "low risk", she added, noting one third of new infections are among married women.
"In Thailand it's a shift, it is not the same people who are infected today as who were infected 10 years ago. The sex industry, we can say, is safe but the government neglected grossly the problem among injecting drug-users," Piot said.
Aid agencies called for a funding boost to provide access to anti-retroviral drug treatment, which only 1.65 million or 24 percent of the 6.8 million people in need are receiving.
"As the yearly ritual of the UNAIDS figures comes round again, leaders of the rich world should be reaching for their collective chequebooks," said the London-based group ActionAid.
Paul Zeitz, head of the Washington-based Global AIDS Alliance, said that with the epidemic outpacing control efforts, governments had to keep promises to provide essential services.
The report cited evidence of diminishing or stable HIV spread in most east African and west African countries, while epidemics still grow in Mozambique, South Africa and Swaziland.
In South Africa, where an estimated 5.5 million people have HIV, the epidemic continues unabated, suggesting the disease's prevalence has not yet reached a plateau, the report said.
In Asia, an estimated 8.6 million people are living with HIV, an increase of nearly one million, and 630,000 people died from AIDS-related illnesses in the vast region this year.
India, where the epidemic appears to be stable or diminishing in some parts while growing modestly in others, has 5.7 million infected people, mainly through heterosexual sex.
