Infection of AIDS

According to a report of the World Health Organization,this year will see 2.6 million deaths from AIDS,the highest yearly international total since the disease began to take hold in the late 1970s, despite questionable antiretro-viral drugs（抗逆转录酶病毒药）that staved off AIDS deaths in the richer countries.
As things stood,the number of deaths was likely to increase for many years before peaking. The report said about half of all people who acquired HIV become infected before they turned 25 and usually died before their 35th birthdays of AIDS,which destroys the body’s immune methods.
Although ninety-five percent of people with HIV live in the developing world,battling HIV rates was still a challenge in the developed countries of the West,where there are"very worrying facts" that safe sex practices are dropping among gays.
While AIDS deaths in the United States dropped by 42 percent between 1996 and 1997,the figure dropped by only half that between 1997 and last year.
The report added that in Eastern Europe and Central Asia,the number of infected people had risen by a third this year,to 360,000.
This was mainly due to an increase in the use of infected needles to inject drugs in Russia and the Ukraine. More than 2,700 cases of HIV were reported in Moscow in the fitst nine months of this year.
Although cases of HIV remain relatively low in the Middle East,increasing use of injected drugs accounted for two thirds of new HIV cases in Bahrian last year,half in Iran and more than a third in Tunisia.
