Young people are increasingly responsible for the spread of HIV/AIDS around the world because of poverty and a severe lack of information and prevention services, the United Nations said Wednesday. Every 14 seconds someone ages 15 to 24 is infected with the virus. That age group accounts for half of all new cases of the disease, the U.N. Population Fund said in its annual State of the World's Population report. "We will have a global catastrophe if we ignore young people and ignore their needs," Thoraya Obaid, the agency's executive director, told a news conference in London. The "Making 1 Billion Count" report cautions that there is now the biggest generation of adolescents in history - 1.2 billion of the world's 6.3 billion people are 10 to 19 - and many are facing deadly diseases, unwanted pregnancy and poverty. HIV/AIDS has emerged as one of the greatest threats. Aside from the high infection rate, the epidemic also has orphaned 13 million children under age 15, the report said. Troubling trends If those trends continue, the next generation of adults will face greater poverty and stunted economic progress, the report said. The report estimates the economic benefit of a single averted HIV/AIDS infection is ,600 for a poor country, and the social benefits are even greater. It called for more investment in youth-friendly services, family planning and education programs to help young people with reproductive health issues. "This is a huge opportunity. It is a one-time opportunity that will not occur again," said Alex Marshall, an author of the report. Poverty is a factor in the spread of HIV, the report said, because some poor girls exchange sex for money for school fees or to help their families, placing them at risk of infection. Discussing sexual behavior is taboo in many countries, so many young people do not know how to protect themselves. In Somalia, the report says, just 26 percent of adolescent girls have heard of AIDS and only 1 percent know how to protect themselves. Obaid said she didn't believe educating youngsters about safe sex would make them more sexually active. "I would like to stress that giving young people this information is safe; it doesn't lead to promiscuous behavior, as some people say," she said. "On the contrary, it empowers young people to take positive action in their lives and may save their lives as well." Obaid said the U.N. agency's core message was ABC: abstaining from sexual activity, being faithful to one partner and the correct use of condoms. In sub-Saharan Africa, which has the most cases of HIV/AIDS among youths, about 8.6 million have HIV/AIDS, two-thirds of them female. In South Asia, 1.1 millions youths are infected, 62 percent of them female. Russia, India rates up The rate of new infections also is growing rapidly in countries like India and Russia, Marshall said. The U.N. report also said poverty, early marriage, unwanted pregnancy and homelessness were major issues facing the world's adolescents. Half are poor and a quarter live in extreme poverty: less than a dollar a day. Among the poorest and least-educated populations, early marriage of girls and expectations of early childbearing persist, contributing to high maternal mortality and reducing girls' chances for education. Teenage mothers are twice as likely to die in childbirth as women in their 20s; girls under 16 are five times more likely to die than women in their 20s; and 14 million young mothers aged 15-19 give birth each year.
