     Has long been engaged in AIDS prevention, treatment, research professor at the Shanghai CDC and Culture to life-long device, popular in Shanghai on the 18th major forum that China's stealth of the number of people living with HIV for more than four million, of which, as the proportion of sexually transmitted accelerate上升.

     Kang Lai-yee said that according to the Chinese Ministry of Health report, as at the end of last year, China's AIDS for more than 270,000. Experts estimate, however, the actual infection may be 700,000
Above. AIDS in China in 2005 two decades ago, the proportion of sexually transmitted less than 10%. However, in 2008, the proportion of sexually transmitted achieve 45.8% growth rate significantly. And drug abuse and other drop in the proportion of transmission.

     Kang Lai pointed out that the sexual route of transmission in homosexual AIDS again the increase in the most obvious: in 2005 Shanghai homosexual AIDS infection rate is 1.5 percent, to 2006 points, the infection rate reached 4 percent First, in 2007 has been as high as 7.5%.

     It is reported that a number of provinces and cities of China has set up task force to intervene in high-risk groups, places of publicity in high-risk AIDS prevention and control knowledge. Kang Lai-yee said that after the efforts of the Shanghai underground condom use sex workers in 2001 from 14 percent of the upgrade to the current四成以上. This is very beneficial to the prevention and control of AIDS. (In the morning light)

     In the host and the environment under the Comprehensive 28-year history of the human AIDS virus, the recombinant variant increasingly "reckless." Held in Shanghai yesterday, popular science talk on the second major forum, the Shanghai Center for Disease Control and Prevention to Professor Miriam Kang said, at present, HIV variation in the global restructuring of up to more than 40 kinds of subtypes, most of which are distributed in China, which to the clinical diagnosis of AIDS and vaccine development is very difficult to bring.
    
     Variation has been the law of the survival of the virus, the risks of HIV is no exception. Distribution of the national HIV survey, in 1996 -1998 years, a single subtype of HIV accounted for more than half of the type, subtype recombinant less variation; the years 2001 -2003, the proportion of a single subtype to 29.1 %, and the reorganization of variation as high as 50.2% subtype.
    
     Accelerate the restructuring of the mutation and transmission of HIV infection is closely related to the change. Kang Lai pointed out that currently, China's new AIDS cases made to the main sexually transmitted infection ratio increased year by year. Condition, according to the National AIDS sentinel surveillance showed that in 1985 -2005 in 20 years, sexually transmitted infections in the total number of AIDS cases in less than 10%; last year, this figure rises to 45.8%. Among these, the male homosexuals is becoming a high risk of infection can not be neglected in the crowd.
    
     HIV drug resistance have been manifested. The national rate of HIV drug resistance monitoring shows that the years 2004 -2005, early and late first-line treatment of drug-resistant rates were 20.9% and 1.6%; in 2006 -2007, the two treatment resistance rate rose to 25.7% and 9.2%. Interestingly, different drugs have actually occurred between the cross-infection. For example, a so-called TDF treatment of AIDS has not yet been used in China, has been demonstrated in the laboratory, 10.2% in the high resistance rate.
    
     "Virus without passports, but also do not need a visa, they can travel around the country, around the world." Kang Lai-yee humorous words intended to convey to the audience the fact that a severe - the floating population will become a bridge for the spread of AIDS groups, the prevalence of long-term factors are widespread . In this regard, to Miriam, Culture and Sport has repeatedly stressed the importance of international cooperation. "So far, smallpox is the only human infectious disease eradication. Vaccinia story tells us that the fight against infectious disease needs the concerted efforts of all countries in the world."
