联合国表示，艾滋病毒新感染病例在过去10年的时间里下降了近20%，但是仍然有3千3百多万人感染了这种病毒。
联合国艾滋病规划署在星期二公布的一份报告中说，艾滋病毒的新感染率至少在56个国家已经稳定下来或大幅度下降，其中包括34个撒哈拉以南的非洲国家。这是艾滋病毒和艾滋病疫情最严重的地区。
这份报告说，非洲受艾滋病疫情影响最严重的5个国家中的四个-埃塞俄比亚、南非、赞比亚和津巴布韦的新艾滋病毒感染率下降的幅度超过了25%。另外一个国家尼日利亚的感染率已经稳定下来了。
不过，联合国的这份报告注意到，世界上将近70%的新的艾滋病毒感染病例仍然在撒哈拉以南的非洲国家。
报告还表示，新的艾滋病毒感染率在其他一些国家里增加了25%，这些国家大部分是在东欧和中亚。
The United Nations says the number new HIV cases has dropped nearly 20 percent in the past decade, but more than 33 million people are still infected by the virus.
In a report Tuesday, the U.N. AIDS agency found the rate of new HIV infections has stabilized or dropped sharply in at least 56 countries, including 34 in sub-Saharan Africa -- the region hardest hit by HIV-AIDS.
The report said Ethiopia, South Africa, Zambia and Zimbabwe -- four of the five African countries most affected by the epidemic -- have reduced rates of new HIV infections by more than 25 percent. The rate in the other country, Nigeria, has stabilized.
However, the U.N. report noted that nearly 70 percent of all new HIV infections in the world are still in sub-Saharan Africa.
It also said new infection rates have increased by 25 percent in some other countries, mostly in eastern Europe and Central Asia.
