dr. fauci says while treatment is crucial, prevention should be prioritized in the first place to reduce infection.

"finally, in prevention, there are a number of proven prevention strategies that we know work. everything from counseling and media campaigns to distribution of condoms, needle exchange programs, circumcision, prevention of mother-to-child transmission. again, that's the good news. the sobering news is that globally, less than 20 percent of people who would benefit from prevention modalities actually have access to them.

More media coverage is being paid to the HIV/AIDS situation in China, especially after a gathering of leading officials, scientists, medical workers and activists in the field occurred in Beijing on November 10. By official estimates, China has 840,000 people carrying HIV, the virus that causes AIDS, and about 80,000 AIDS patients. Despite the fairly large groups of HIV carriers and AIDS patients, the epidemic is mostly confined to high-risk groups, such as drug users, prostitutes and users of blood products.

And it has yet to spread widely in the rest of the nation. The Chinese Government is well aware of such perspectives, and the central and local governments have allocated 6.8 billion yuan (US$822 billion) to establish and improve disease prevention and control mechanisms in provinces. Each year a special fund of more than 200 million yuan (US$24 million) is channeled into HIV/AIDS prevention, care and treatment. Since April, free medicine to poor AIDS patients has been delivered in regions hit hardest by the virus. Just as the impacts of AIDS reaches social and economic fields of society, effective prevention also requires united efforts from virtually all sectors. Key factors needed include public education, affordable drugs, medical training for healthcare workers in hospitals and the public health system, monitoring and evaluation, care for orphans.

measures to stop mother-to-child transmission, a comprehensive care framework and research into vaccines and a cure.

None of these things can be achieved with the single hand of any institution — not health officials, not medical workers or the government. The fight against HIV/AIDS requires the participation of as many parties as possible. As former US President Bill Clinton said as a co-chair of the advisory board of International AIDS Trust, the AIDS problem is “manageable and preventable” though we must wage it on all fronts with tenuous determination, utmost patience and tactful skills.

AIDS, stands for Acquired Immune Deficiency Syndrome, is a deadly disease. It malfunctions the human body's defence system, making the infected person extremely vulnerable to diseases, and eventually cause death.

AIDS can be spread in many ways, but the main medium is through having unprotected intercourse with an infected person. Apart from that, AIDS can spread from mother to new born baby, or sharing of needles, shaving blades, or any means of blood contact.

Once infected, it may take years for the person to notice, and in these years, the infected person may not know and can infect many more, who in turn go and infect others, just like an exponential growth.

HIV has been a widespread epidemic for over 30 years now; despite recent setbacks, researchers around the world are still heavily mitted to developing a vaccine that will stop the virus in its tracks and help the millions of people who have yet to suffer its wrath. Now, some researchers are looking for answers to help fight the battle in a place where we might not have searched before: the human mind.

The Economic and Social Research Council recently funded a new study that shows human hope might be a very strong and overlooked tool to help in the war with AIDS. In a nutshell, the study determined that people who had goals and definitive plans for their futures (whether that involved careers, relationships, children or the like) were more likely to stay away from any situations that would give them a high risk of contracting a disease like AIDS; on the contrary, those people who did not have many high hopes for their own future were more likely to engage in actions that would put them at a higher risk. One example widely used in the study is of men who do not have any ambitious hopes or goals for their future – when engaging in sexual relations, they are less likely to wear a condom because the instant gratification and pleasure they feel when they do not wear a condom takes precedence over the future risk.

Tony Barnett, a professional from the London School of Economics, agrees with the study, “Current policies to tackle HIV/AIDS in Africa emphasize individual behavior such as the ABC approach to prevention: Abstain, Be faithful, Condomise. However, these measures require that people have hope for the future and goals to aim for. And if wider economic and social circumstances are so poor that people lack hope for the future, then these current policies will have limited success.” A prime example of this can be seen in the global fight against AIDS: while moderate success has been had in Western civilization, there has not been as great a degree of success in African nations. Consider the fact that in the country of Botswana, the life expectancy is 36 years for somebody with AIDS pared to 71 years for somebody who has not contracted the disease. Recent estimates have shown that within the next decade, the life expectancy may plummet even more to 30 years.

Studies like this one are demonstrating that in order to strengthen the fight against AIDS, researchers need to not only focus on a person’s behavior (as many research studies do), but their cultural, economic and social background as well. Researchers in the field of AIDS/HIV studies need to strongly consider that for most people, hope for things like a secure future, a successful adulthood and an ever-growing family tree have an enormous impact on the decisions an individual makes throughout his/her life. Having a disease like HIV/AIDS can literally destroy a person’s chances for any kind of hope which, in turn, can affect the entire society as infection rates soar. In Africa, for instance, where most people have little educational and financial support and, thus, bleak futures, young adults are more susceptible to contracting HIV at some point in their lives. Barnett states, “Hope is quite straightforward to measure via questionnaires and surveys can help to identify high risk environments. Although there is not a great deal of experience in developing programs to increase hope, policies such as cash support for children, microfinance for small businesses, women’s education, reduced discriminations against sexual minorities and health system reform will improve the wider environment. And with more to live for, interventions to encourage individuals to change their behavior are more likely to succeed.”

The uniting of the world around the AIDS epidemic is without prior example. As the number of AIDS cases around the world rapidly increases, nations are showing great focus in battling this common enemy — attacking rich and poor countries the same.

By 89, almost every nation on earth had established a program educating its people about AIDS, according to Jonathan Mann, director of the World Health Organization's (WHO) International Program on AIDS. At that time, 143 countries had reported one or more AIDS cases.

In addition to national AIDS programs, working together internationally has begun. Through open exchanges of scientific facts as well as support of international organizations such as the World Health Organization, all nations can join efforts to fight against this life-threatening disease. According to WHO, this international effort has produced two critical developments: first, there is an amazing level of world—wide focus, using world scientists and international sharing of human and economic resources to fight AIDS. Second, the work of governments, organizations, and businesses has been followed by the very high activity of people - as singles, families, and communities.

The Influence of AIDS

The rise of acquired immune deficiency syndrome (AIDS) around the earth has represented a major challenge to medical progress both in developed and in less - developed countries. The past forty years saw great success in the control of spreading diseases and great strides toward achieving "health for all by the year 2000" (a major WHO goal) through improved basic health care, food, cleanliness, and immunization(免疫) programs.

Yet, because of its sudden start and rapid spread, AIDS could soon wipe out this progress. By the end of 1988, more than 130,000 cases of AIDS were reported, but, because of under reporting, there may actually be more than 350,000 cases. Also, at least five million persons likely have the human immunodeficiency virus (HIV) (艾滋病病毒), which causes AIDS. That means as many as 400,000 new cases of AIDS could occur in the next few years - more than doubling the present total. Caring for AIDS patients could seriously stress economic resources even in richer countries.

Preventing one case of AIDS means preventing many future cases, while preventing a case of measles(麻疹) or malaria(疟疾) in Africa would have little effect on its spreading, since those diseases are already common in many countries. Resources devoted to AIDS testing, care, and education could also be used to battle other, more-known diseases in developing countries.

Stopping the Spread

AIDS spreads only in limited ways and can be prevented through informed and mature behavior. Encouraging such behavior depends on understanding the different ways AIDS is spread around the world. AIDS spreads in three basic ways: first, through sexual intercourse(性交); second, through contact with diseased blood; and third from an HIV mother to her baby. The actual patterns of spreading of the AIDS virus change from culture to culture.

Spreading of AIDS in North America, Western Europe, Australia, New Zealand and parts of Latin America occurs most often among homosexual(同性恋) or bisexual(双性恋) men and intravenous (IV) (静脉内注射的) drug users(吸毒者), most often in city areas. Heterosexual(异性之间的) spreading is low, but there is danger that the spread of AIDS from male(男性) IV-drug users to their female(女性) partners could increase the appearance of AIDS in the heterosexual population.

In sub-Saharan Africa and Latin America, particularly the Caribbean, most cases occur among heterosexuals, and spreading from mother-to-child is common. Spreading through homosexual contact and IV-drug use almost does not exist.

In Eastern Europe, northern Africa, the eastern Mediterranean, Asia, and most of the Pacific, fewer cases of AIDS, usually among drug users, have been reported thus far. The WHO estimates that Bangkok, Thailand IV-drug users having the AIDS virus increased from less than 1 percent in August 1987 to 30 percent one year later.

Reaching Out

WHO believes that, as AIDS becomes more common, the disease promises to unite the world to a degree never seen before. In just two years, the international plan against AIDS has grown from ideas to practice, from speeches to action. WHO is certain that, together, we will triumph over AIDS rather than allow the disease and the fears, worries, and prejudices(偏见) which go with it to overpower us.

As I just witnessed during my recent visit here, China has made substantial progress in checking the spread of HIV but there is still a long way to go. From an infection unknown only 27 years ago, AIDS has become truly globalized. Today, 33 million people live with HIV around the globe, and 25 million more have died.

These figures are sobering. However, it is important to note that we have entered a new phase in responding to AIDS - a phase that will ultimately be far more challenging than anything we have done so far.

Now, for the first time, the AIDS response is producing real results.

In 2007, fewer people got newly infected and the number of people dying of AIDS worldwide dropped, mainly thanks to better access to antiretroviral treatment.

In China, over 34,000 people are now taking HIV drugs, up from 5,000 in 2003. But, we cannot slow down in our vigilance. Whereas substantial progress has been achieved in this country, the number of people receiving HIV drugs is still less than half the number who require them. The epidemic continues to run ahead of the response: for every two people who start taking antiretroviral drugs, another five become newly infected with HIV.

Many of those infections occur in situations that are illegal or outside of mainstream society. These give rise to apparent contradictions between respect for the law and protecting the health of people who inject drugs or are sex workers, between sexuality and morality, between needs of public security and public health, drug control and safe injections. Indeed, to confront AIDS is to confront contradictions in society.

On closer investigation, however, most of these contradictions prove to be false contradictions. A scientifically-based AIDS response can solve them for the greater wellbeing of more people.

Drug abuse, for example, is bad for an individual's health and for the community he or she lives in. HIV infections are particularly high among people who inject drugs. Laws against drugs must be respected to protect society.

Ultimately, though, the best way to protect both the wider population and drug users, and at the same time reconcile public security and public health concerns is to adopt the "harm reduction" approach. Scientific evidence - including here in China- shows that providing drug users with substitution therapy and clean needles reduces HIV transmission and supports enforcement of laws against drug abuse.

Similarly, working with sex workers and their clients to encourage condom use reduces HIV among these groups and in society as a whole. When such programs are backed up by poverty reduction efforts to reduce women's need to engage in prostitution, their impact is even greater.

It is issues such as these that make AIDS such a complex problem to deal with. Complex problems require complex solutions. They also respond best to collective approaches. Working with community groups, for example, can greatly increase the impact - and effectiveness - of AIDS strategies. In fact, given that most infections are happening in situations outside the mainstream norm, it is often very difficult for government alone to reach those who need to be reached.

It is encouraging, therefore, to note that there has recently been an increase in the number of community organizations working on AIDS in China. Many of these groups are doing incredible work.

The Joint Assessment Report published last year by the government together with the United Nations System clearly highlights the need for greater involvement of community-based organization in the roll-out of programs to reach people with relevant services.

Currently, there are no easy ways for community-based organizations to register. Without registration, there can be no bank account and thus no easy way to receive funding. Many of the groups I have seen are doing a great job - but their work is based on volunteerism. This is neither efficient nor sustainable.

China has solid policies in place and has made significant progress in the fight against AIDS. It is time now to use the tremendous array of resources at its disposal to build on that progress, and to tackle new, tough challenges like harm reduction and increasing civil society involvement,

As Chairman Mao said more than 60 years ago: "We must not become complacent over our success. We should check our complacency and constantly criticize our shortcomings, just as we should wash our faces and sweep the floor every day to remove the dirt and keep them clean."

Yes, AIDS does erod the people's aesthetic life, but on the road we rushed to a better tomorrow, the rich people are everywhere, I have a great force in the invisible and tangible season. Power. The strong family can always move the world.

I believe that as long as we firmly believe, love forever, truth, heart-sightedness can curb the spread of AIDS, grow, will become better.

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 that 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？

Without more incisive , focused behavioral research, prevention messages alone will not stop the global epidemic.
