What are the ways of transmission of AIDS? Three conditions are needed for the spread of AIDS
Japanese researchers have found that HIV-infected cells transmit the virus directly when they come into contact with other cells, which is the main way for the virus to multiply in the body. The researchers believe that if the direct contact infection of this kind of cells can be suppressed, it is expected to improve the therapeutic effect of AIDS.
Previous studies have found that when HIV infects cells, there are usually two ways: one is for the virus to leave the infected cells, enter body fluids, and then invade other cells to infect them; the other is to transmit the virus when infected cells come into direct contact with other cells. However, it is not clear how much effect these two ways have on the proliferation of HIV.
The research team led by Associate Professor Makoto Iwaki of Kyushu University in Japan cooperated with researchers from Kyoto University and the University of Tokyo to cultivate HIV-infected cells and conduct experiments. They put the containers in which the cells are cultured on a vibrating device, which vibrates continuously so that the cells cannot come into contact directly. The results showed that continuous vibration significantly reduced the rate of HIV proliferation compared with static container.
Detailed-gt; detailed analysis, in this experiment, the proportion of cell contact infection in HIV infection is about 60%. When the cells were in contact, the infection rate was about 3.9 times higher than that without contact.
Introduction to the mode of transmission of AIDS
1. Touch propagation: including the touch between similarities and differences. There is a greater risk of infection. AIDS infected people's semen and vaginal secretions have a lot of virus, activity (), due to cross-site conflict, easy to cause minor damage to the genital mucosa, the virus uses weakness to enter into the blood of the uninfected. It is worth mentioning that the rectal wall is more likely to be damaged than the vaginal wall bad dragon dildo , so the risk of anal intercourse is greater than that of vaginal intercourse.
2. Blood transmission: ① input contaminated HIV blood and blood products ② intravenous drug users contaminated with HIV, unsterilized needles and syringes ③ sharing other medical devices and daily necessities (sharing toothbrushes, razors, etc.) can also be infected in damaged areas, but rarely. Disinfection of ④ syringes and needles is not complete or not. In particular, there is a greater risk of injecting one person with one injection in children. Oral instruments, midwifery instruments, surgical instruments, needles for treatment of needles that are not sterilized or not sterilized. Hairdressing (eyebrows, ears, etc.), tattoos and other knives, needles, bathroom pedicure knives that do not disinfect the blood and blood products of blood donors who share razors, razors or HIV antibodies with shared toothbrushes. And the movement values of bone marrow transfusions and organs in similar cases
3. Mother-child transmission: also known as perinatal transmission, that is, mothers infected with HIV infect their fetuses and babies before giving birth, during and shortly after giving birth. It can be infected through the placenta or through the delivery road or lactation during delivery.
Three conditions for the spread of AIDS
1. HIV infection exists.
There must be a source of HIV infection before HIV infection and transmission can occur. Some people worry and suspect that as long as you have sex, you will get AIDS big ass , even without HIV, this view is also wrong.
2. Sufficient amount of virus is excreted from the infected person.
Only when the number of HIV reaches a certain level can it lead to infection. For example, infected people have more viruses in their blood deep anal dildo , semen and milk bullet vibrator , and only a small amount is enough to infect others, and the risk of exposure to these bodily fluids is relatively high. There is little or no virus in saliva, tears and urine, and daily contact does not transmit HIV.
3. HIV must enter the blood of the infected person.
Only contact with virus body fluids is not enough to infect HIV, healthy and lossless skin can prevent HIV from entering the body and effectively prevent HW infection. HIV can enter the body through wounds or ulcers, or through mucous membranes such as anus, rectum, reproductive tract, mouth, eyes and so on.
