The latest report on the Global AIDS epidemic 2007 released by UNAIDS and the World Health Organization on November 20, 2007 estimated that there were 33.2 million people infected with HIV in the world in 2007.
The number of adults infected with HIV has been stable in recent years, accounting for about 0.8 per cent of the world's population. More than 2.5 million people were newly infected with HIV in 2007.
The study also shows that AIDS patients will no longer infect others if treatment is effective. But the Swiss Federal Committee on AIDS also made it clear that this is only for a small number of AIDS patients who insist on treatment, while other people living with HIV have to comply with the relevant safety regulations.
Effective treatment can replace condoms, but three conditions must be met to prevent virus transmission: the virus in the blood is suppressed and there is no virus in the blood at least six months ago; patients must adhere to treatment and check regularly; virus carriers must ensure that there are no other infectious diseases.
Whether the virus in AIDS patients will be transmitted to others or not should be verified by the treatment doctor. It is speculated that there are only about 1000 people who really have these three conditions in Switzerland

For these patients who are "relieved", this is undoubtedly good news, which can improve the quality of life. They can also have children without having to worry about their children being infected with HIV. After this so-called "anti-retrovirus" (antiretroviral) treatment, the life expectancy of AIDS patients can be exactly the same as that of an ordinary person.
Pietro Vernazza, head of the Swiss Federal Council on AIDS and a professor at St. Gallen University, explained: "Infectious disease research results over the years have shown that HIV transmission is related to the concentration of the virus in the blood." After antiretroviral therapy, the virus disappears from the blood. "
What is also certain is that after treatment, the virus can even disappear from sexual secretions, experts said. Therefore, after treatment of patients, the possibility of infection becomes very small.
This new understanding of AIDS is the result of years of research. In one of the surveys conducted in Spain, 393 couples with HIV were followed for 14 years, providing valuable material for the study.
Previously, the University of Lobsang in Switzerland and American scientists found that 2% of people were born with resistance to HIV. Researchers have found that three genes in the body play a decisive role in this self-protection function in people infected with HIV.
Among people infected with HIV
dildo machine lesbian vibrator , the human tissues of different people also react differently to the virus. Some people have complete control over HIV in their bodies, while others quickly develop AIDS and die soon. The researchers concluded that resistance to AIDS is related to genes. After analyzing millions of data, researchers have identified the types of DNA that play a decisive role in the body's resistance to HIV.
Vernazza said that Switzerland is at the forefront of the world in understanding AIDS.
