WASHINGTON, Nov. 25 (Xinhua) -- In the United States, the AIDS epidemic has plateaued, but it is still at "unacceptable high" level, a U.S. expert said ahead of the World AIDS Day."The situation is stable in the United States, stable in an unacceptable high level for at least 10 years and has not gone down. It's still a serious problem," Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), told Xinhua in an exclusive interview.According to Fauci, there are about 1.1 million people infected with HIV in the U.S., of which about 20 percent do not know they are infected. Those are the ones that more likely will infect other people. Since the world's first AIDS case was reported 30 years ago, the U.S. has seen close to 600,000 AIDS-related death. And among the 65,000 new infections each year in the U.S, about 50 percent are African Americans. In the United States, about 12 percent of the population is African American."Our new approach to prevention is to try and get access at community level, to people at most risk, to seek out to voluntarily test, to link them to care, and to automatically get them treatment," said Fauci. "When you get someone on treatment, it is extremely unlikely that they will infect their sexual partner."Fauci thought the international community's battle against the HIV/AIDS has gotten better over the last 30 years.Early on, when the disease was inaccurately thought to be a disease of developed world. There was a denial in many countries in Asia, in Southern Africa, South America and Caribbean, that this will turn out to be an extraordinary problem in those countries. As the years went by, it was clear that it was not a disease of gay men in the United States and the developed world. It was a disease mostly in the developing world when 90 percent of new infections occur in low- and middle-income countries and 67 percent of the cases are in Southern Africa."The response of the global community first was denial and not full appreciation of the potential impact of the pandemic. As the years have gone by, the response has been better and better," said Fauci, an immunologist that has made substantial contributions to research in the areas of AIDS and other immunodeficiencies, both as a scientist and as the head of NIAID.The advance in the arena of therapy with drugs has been " spectacular" and "very impressive", he said.In the early 1980 before there were any drugs, the median survival period of people in the United States who was infected with HIV, was about six to eight months. "Today in 2010, if someone was newly infected with HIV and he's 20-25 years old, and you put them on therapy, you can predict mathematically that they will live additional 50 years," said Fauci.Over the last couple of years, there has been "significant but slow" advances with vaccines against HIV. For example, there was a trial that was conducted in Thailand in which there was a modest degree of efficacy, about 31 percent of protection."That's not enough to have a vaccine available for widespread use but give us some important clues into what next generation of vaccines would be," said Fauci.As to the "three zeros" target adopted by the United Nations this year, Fauci said that it's "aspirational but not gonna be easy.""It is good to set very high goals for the future. I don't think that we realistically are gonna get to zero new infections, zero new discrimination, zero (AIDS-related) death in the next few years," said Fauci. "I think it will take several years to get there. I believe that if more countries and the international community are engaged to play a role in trying to stop HIV, to prevent and treat and care for HIV-infected individuals, that we will automatically achieve that objective."

BEIJING, Oct. 12 (Xinhuanet) -- Study found that women who took multivitamins may actually be at risk, media reports on Wednsday.Women who took the dietary supplements vitamin B6, folic acid, magnesium, zinc, copper, iron and multivitamins had a higher risk of death than women who did not.The new study, published in the Archives of Internal Medicine, examined more than 38,000 women aged 55 and older who took part in the Iowa Women's Health Study, which started in the mid 1980s. Researchers found the vitamins did nothing to reduce the risk of death and that most supplements have no positive effect on women's health.The study did not distinguish if the women in the study took the vitamins to fight diseases or to maintain health.Vitamin experts say the best way to make sure you are getting all necessary vitamins is to eat a well-balanced diet. The vitamins people take do not  depend on personal preference.

SAN FRANCISCO, Oct. 14 (Xinhua) -- Google on Friday announced to shut down the highly-controversial social networking product Google Buzz, along with several other services in the coming weeks.On the company's official blog, Google announced the death penalty to its code search engine, Buzz, Jaiku which let users send updates to friends, the Google personalized homepage feature iGoogle, and the University Research Program for Google Search.The shut-downs came as part of Google's housecleaning effort announced in early September, in which the company said it will shut down a number of products and merging others into existing products as features."Changing the world takes focus on the future, and honesty about the past. We learned a lot from products like Buzz, and are putting that learning to work every day in our vision for products like Google+. Our users expect great things from us; today's announcements let us focus even more on giving them something truly awesome," said Google in the blog post.Google Buzz, a social networking and messaging tool integrated into Gmail service, has been widely criticized for privacy concerns and held back the search giant from expanding its businesses to the social networking space.After Buzz, Google launched Google+ in June, which has been receiving a good response and passed the 40 million user mark, the company's chief executive officer Larry Page said Thursday.

BEIJING, Dec. 2 (Xinhua) -- Medical experts and leaders from the world's leading orthopaedic societies on Friday called for the improvement of health insurance programs and medical care for people in developing countries."Health care should reach the unreached," said Professor H.K.T. Raza, president of the Asia Pacific Orthopaedic Association (APOP), at the Sixth International Congress of Chinese Orthopaedic Association (COA), which is running from Thursday to Sunday in Beijing."If we really want to improve people's well-being, we have to make health care available to those who have difficulty accessing it. Although that will probably be a very difficult task, we should try and do it gradually," said Professor K.M. Chan from the Prince of Wales Hospital in Hong Kong.Statistics from the Ministry of Health show that 1.27 billion Chinese, or 95 percent of the country's population, are covered by basic medical insurance programs.However, private medical insurance accounts for less than 2 percent of the country's health care financing, while private insurance in other countries stands at an average of 20 percent."With the increasing demand for quality health care, there will be higher demand for commercial insurance. With more private health funding in the system, we can increase the quality," Prof. Chan said.Government health care expenditures should be directed toward those who can't afford health care at all, while commercial insurance should cover the needs of those who can afford to purchase it, Prof. Chan said."We need to have different approaches combined together to revamp the current health insurance structure in China," he said."If you want to raise the quality of health care, you need to have the responsibility from the government, the individuals and the insurance system," he added.While China may need to promote its commercial health insurance, in India, the situation is different. Though many medical tourists choose India as their destination for affordable care, health insurance is uncommon in the country.While patients typically pay out of their own pockets for routine care, it is estimated that over 300 million Indians out of a population of 1.2 billion still live on less than one U.S. dollar per day.
