Latest data shows an estimated 39.5 million people around the world are living with HIV, the virus that causes AIDS. According to the report, this means every eight seconds somebody in the world is infected with HIV, resulting in 11,000 people becoming newly infected every day.
The director of UNAIDS, Peter Piot, says most of the new infections, nearly two-thirds, are in Sub-Saharan Africa. But, the biggest increases are in Eastern Europe and Central Asia, where infection rates have risen by more than 50 percent since 2004. He says 2.9 million people died from AIDS-related illnesses this year, the highest number ever.
UNAIDS senior epidemiologist(流行病学家), Karen Stanecki, says infections are rising in countries where HIV prevention programs have not adapted to the changing nature of the epidemics(流行病).  Stanecki noted，"In Thailand, one of our past success stories, a large percentage of new HIV infections are occurring in people considered to be low risk. One third of new infections are among married women."
It says data shows increased use of condoms has resulted in drops in HIV prevalence(流行) among young people between 2000 and 2005 in a number of African countries, including Botswana, Kenya and Zimbabwe. Nevertheless, the report notes young people between the ages of 15 and 24 account for 40 percent of new HIV infections. It finds the risk behavior, such as injecting drug use, homosexuals, is a factor of concern in many regions of the world, especially in Asia, Eastern Europe and Latin America.
The report notes the emergence (出现) of injecting drug use as a factor of HIV in Kenya, Tanzania, Nigeria and South Africa is a recent development in Sub-Saharan Africa.
