According to the data released by the National Health Commission, the number of AIDS cases in China increased from 809,000 at the end of 2065,438+03 to 654,380,250 at the end of 2065,438+08, with a compound annual growth rate higher than the global level. According to the data of the National Health Commission, the HIV infection rate in China is nine in ten thousand.

If we add more undiscovered people, every 1000 people in China will be infected with AIDS! This is really a shocking data!

Data show that China has basically blocked the spread of AIDS through blood transfusion. Mother-to-child transmission has dropped from 7. 1% in 20 12 to less than 4% at present, which is at the lowest level in the past years. However, the overall situation of AIDS in China is still on the rise, which shows that AIDS caused by sexual transmission is on the rise. The survey data in the past five years support this conclusion. The survey shows that in 15? Among the 24-year-old population, 96% contracted AIDS through sexual transmission.

Therefore, condoms should be used to block the spread of AIDS. Why can condoms block the spread of AIDS? You can look at the following products of a high-tech company in Guilin: Beryl Lehuadun condom.

China invention patent: highly blocking the penetration of germs.

Patent number: ZL 20 10533 47 1.0.

The structure of compound barrier condom is: three-layer compound. Both sides are new natural latex, which is rich in some active ingredients. The middle layer is sandwiched by a layer of modified nano-materials (modified polyurethane layer), and the molecular gap is about less than 30 nm. These three compounds become a new type of compound barrier condom.

//Repeated tests by authoritative inspection and testing institutions//

The compound barrier condom was observed by 10000 times electron microscope in the physical materials laboratory of East China University of Science and Technology. It can be clearly seen that the compound barrier condom is obviously divided into three layers. The hole between the two latex layers (A\C) is very large, while the modified nano layer (polyurethane layer) in the middle layer (b) is very dense.

Further detection by Shanghai Institute of Microscopic Spectroscopy shows that when the cross section of the product is enlarged to 20000 times, the diameter of the "pit" brought by other particles is 284 nm when the cross section is cut off. As a contrast, putting AIDS-sized particles of 120 nm aside, we found that the overall compactness of the cross section far exceeded the size of HIV. This further proves the barrier performance of the product to HIV.
