WASHINGTON--Nearly 40 million children in developing countries stand (忍受) to lose one or both parents because of AIDS (艾滋病) over the next 13 years, and almost 3 million children under 15 have caught the disease (疾病) worldwide, the US experts said.

　　

　　“More than 40 million children in 23 developing nations will likely have lost one or both their parents by 2010. Most of these deaths will be the result of the HIV/AIDS and complicated illnesses (复杂的病),” Brian Atwood, a US official (官员) said. Meanwhile (同时), since the first reported death of a child by AIDS in Los Angeles 15 years ago, almost 3 million children under 15 are estimated (估计) to have caught the disease worldwide, and at least 1 ,000 are dying each day.

　　

　　“In countries across Africa, Asia and Latin America (拉丁美洲), HIV/AIDS is pulling years of progress in economic (经济) and social development,” he added.

　　

　　“Life expectancy (预计寿命) which has been steadily (稳步地) on the rise for the last thirty years will drop to 40 years or less in nine African countries by the year 2020.” Atwood said serious work to help stop children from dying in developing countries was being wiped out.

　　

　　“In all 23 countries included in this study, AIDS - related death will take away the gains made in child survival (幸免) over the past 20 years. In Zambia (赞比亚) and Zimbabwe (津巴布韦), children' s death rates will likely nearly double,” Atwood said.
