News Agency] Multidimensional News Agency reporter Wang Haichuan reported / Studying AIDS and hepatitis C viruses through genetic fingerprinting, Chinese and American researchers found that the world's most populous country is suffering from the ravages of these blood-borne microorganisms. Another group of researchers also found that HIV mutates at an alarming rate, and the rate of variant emergence far exceeds that of cold viruses, thus posing challenges to vaccine research and prevention.
The "Wall Street Journal" published an article on the 27th that HIV and Hepatitis C are spreading in Southwest China's Yunnan Province, which is close to the "Golden Triangle" where heroin is mainly produced, because drug users share needles to inject drugs. In Yunnan Province, HIV subspecies C is spreading along the ancient "Silk Road", which is now used by drug traffickers as the main route of transportation. Similarly, hepatitis C virus subspecies No. 3 is also the main infectious disease in Yunnan Province.
But in mainland China, mainly in Henan Province, those viruses are mostly spread through blood contamination. Illegal blood banks pay for blood collection, and those who donate blood become infected with HIV and hepatitis viruses. In Henan Province, the HIV subtype B is the main type, and the hepatitis C virus type 1 and type 2 are the main types.
Cao Yunzhen (transliteration), a researcher at the China National Center for AIDS Prevention and Control and a visiting scientist at the Aaron Diamond AIDS Research Center in New York, said that Yunnan Province is an area inhabited by ethnic minorities in China, with low income and poor education. Cao Yunzhen said that the Chinese government's past prevention and control measures have suffered setbacks. New prevention and control pilot projects have recently begun, including educating drug addicts to replace needles, AIDS education for sex workers and cracking down on illegal blood collection stations.
Lynch Zhang of the Elrond Diamond AIDS Research Center presented the findings at the 9th Congress on Retroviruses and Opportunistic Infections, which provide the basis for an experimental AIDS vaccine and an experimental AIDS treatment in China.
In another study, Douglas Richman of the University of California found that the outer membrane of HIV is surprisingly mutable. He said, "The mutation we saw in one patient for six months is equal to the mutation of the global cold virus in ten years." (The reason for this variation is caused by the abuse of Western medicine by Western medicine.)
"That variability poses a challenge for vaccine production, because vaccine manufacturers hope to neutralize the virus by stimulating antibodies that confine HIV within its outer membrane. The rapid mutation of HIV creates a strong selective pressure on the virus, forcing it to continue to grow." Changes that escape the powerful antibodies of the immune system. Li Qiman said that if a vaccine can produce antibodies before AIDS takes hold in the human body, maybe a person will not be infected. (Infected with AIDS"">"
