World AIDS Day, observed December 1 each year, is dedicated to raising awareness of the AIDS pandemic caused by the spread of HIV infection. It is common to hold memorials to honor persons who have died from HIV/AIDS on this day.

Government and health officials also observe the event, often with speeches or forums on the AIDS topics. Since 1995, the President of the United States has made an official proclamation on World AIDS Day. Governments of other nations have followed suit and issued similar announcements。

AIDS has killed more than 25 million people between 1981 and 2007, and an estimated 33.2 million people worldwide live with HIV as of 2007, making it one of the most destructive epidemics in recorded history. Despite recent, improved access to antiretroviral treatment and care in many regions of the world, the AIDS epidemic claimed an estimated 2 million lives in 2007, of which about 270,000 were children。

Started in 1988, World AIDS Day is not just about raising money, but also about raising awareness, education and fighting prejudice. World AIDS Day is also important in reminding people that HIV has not gone away, and that there are many things still to be done.

You may have a memory of the terrifying attacks by AIDS several years ago. A number of people died of the disease. Few months ago, there had been hints that the terrible disease would come back again.Uncurable as it is, we could keep the illness at bay. As far as I am concerned, we has been urging citizens with symptoms of the illness--a sharp increase in body temperature, headaches, muscular pains and breathing problems -- to visit their nearest medical center as soon as possible.

Many people nowadays have taken steps to prevent this terrible thing from stalking all over the world. As far as I am concerned, The Chinese capital has stepped up its efforts to fight AIDS by advocating a healthy ethical manners. The World Health Organization (WHO) said that although China has a strong political determination to tackle the problem and had stepped up monitoring efforts, more needed to be done at the local level.

Bright future is at hand. Maybe, a few years later, the disease will be gone, and a tranquil life may come.

In the 20years since the first cases of AIDS were detected, scientists say they have learned more about this viral disease than any other.

Yet Peter Piot, who directs the United Nations AIDS program, and Stefano Vella of Rome, president of the International AIDS Society, and other experts say reviewing unanswered questions could prove useful as a measure of progress for AIDS and other diseases.

Among the important broader scientific questions that remain：

Why does AIDS predispose infected persons to certain types of cancer and infections?

A long-standing belief is that cancer cells constantly develop and are held in check by a healthy immune system. But AIDS has challenged that belief. People with AIDS are much more prone to certain cancers like non-Hodgkins lymphomas and Kaposi’s sarcoma , but not to breast, colon and lung, the most common cancers in the United States. This pattern suggests that an impaired immune system, at least the type that occurs in AIDS, does not allow common cancers to develop. 　　What route does HIV take after it enters the body to destroy the immune system?

When HIV is transmitted sexually, the virus must cross a tissue barrier to enter the body. How th

at happens is still unclear. The virus might invade directly or be carried by a series of different kinds of cells. 　　Eventually HIV travels through lymph vessels to lymph nodes and the rest of the lymph system. But what is not known is how the virus proceeds to destroy the body’s CD-4cells that are needed to combat invading infectious agents.

How does HIV subvert the immune sys-tem?

Although HIV kills the immune cells sent to kill the virus, there is widespread variation in the rate at which HIV infected people become ill with AIDS. So scientists ask：Can the elements of the immune system responsible for that variability be identified?If so, can they be used to stop progression to AIDS in infected individuals and possibly prevent infection in the first place?

What is the most effective anti-HIV therapy?

In theory, early treatment should offer the best chance of preserving immune function. But the new drugs do not completely eliminate HIV from the body so the medicines, which can have dangerous side effects, will have to be taken for a lifetime and perhaps changed to combat resistance. The new policy is expected to recommend that treatment be deferred until there are signs the immune system is weakening.

Is a vaccine possible?

There is little question that an effective vaccine is crucial to controlling the epidemic . Yet only one has reached the stage of full testing, and there is wide controversy over the degree of protection it will provide. HIV strains that are transmitted in various areas of the world differ genetically. It is not known whether a vaccine derived from one type of HIV will confer protection against other types.

In the absence of a vaccine, how can HIV be stopped?
