Can AIDS be spread by kissing

AIDS, also known as acquired immunodeficiency syndrome (AIDS), is an infection caused by human immunodeficiency virus (HIV) infection, mainly through sexual behavior, blood contact or mother-child contact. After HIV infection, human immune function is suppressed, which is easy to cause virus infection and tumor. Human body infected with HIV will cause the damage of T lymphocytes, cause persistent immunodeficiency, opportunistic infection in many organs and rare malignant tumors, and finally die.
Two kinds of glycoproteins, gp120 and gp41, are embedded in the lipoprotein membrane of HIV in vitro. Gp120 and CD4 glycoprotein on the surface of lymphocytes have affinity, and the specific binding gp41 can mediate the fusion between virus membrane and host cell membrane. Therefore, HIV can reach the blood through other methods such as skin and mucous membrane damage and blood huge ass , and then choose to invade CD4+ lymphocytes.
After HIV invades CD4+ lymphocytes, under the action of viral reverse transcriptase, DNA is synthesized and the chromosomes of host cells are integrated. The integrated viral DNA can replicate in the cell, form a complete virion, release extracellular, cell death, and infect new cells.
At the beginning of the epidemic, a large number of HIV replicates, causing viremia, the expression of shell antigen p24 male chastity cages , and the clinical manifestation of acute HIV infection. A large number of HIV cells replicate, which leads to the damage and death of CD4+ lymphocytes and the decrease of CD4+T cells. However, under the immune action of the body, CD8+CTL is activated to kill HIV infected cells and produce anti-HIV antibodies. Viremia is quickly cleared and the number of CD4+ lymphocytes is restored.
Can kissing spread AIDS?
Can saliva spread AIDS? Generally speaking, kissing does not spread AIDS. HIV exists in infected people's blood, semen, vaginal secretions women vibrator , tears, urine, milk, cerebrospinal fluid, the content of saliva is very small, will not infect the human virus. Under normal circumstances (there is no massive bleeding in the mouth), only saliva contains HIV virus, in order to achieve the effect of HIV infection remote vibrator , it is necessary to put 2 gallons of saliva into the other person's body. In addition, so far, the scientific community has not found any cases of kissing infection.
The treatment of AIDS includes
1. General supportive therapy: including physical and mental recuperation and nutritional supply.
2. Control the treatment of opportunistic infections and malignant tumors: most opportunistic infections have special specific drugs, using a variety of antimicrobial, antifungal and antiprotozoal drugs to treat opportunistic infections of AIDS patients under the guidance of doctors. Malignant tumors are treated by radiotherapy, chemotherapy or surgery as decided by the doctor.
3. Anti-HIV drugs. Directly inhibit the activity of viral reverse transcriptase and prevent the replication of the virus in human cells, such as diazothymidine and DDI. These two drugs are widely used in clinic. After taking drugs, some patients do not completely inhibit the process of virus replication in the body, which can reduce the number of viruses, but after the reduction or withdrawal of drugs, the virus level immediately rebounded, it is clear that these two drugs can not cure AIDS, can only delay the disease and prolong survival.
In recent years, thousands of people infected with HIV in the United States have been treated with AZT. It is found that the use of AZT in advance before the onset of the disease can delay the time of onset. Taking AZT to pregnant women infected with HIV can reduce the risk of vertical transmission of the virus from mother to child, and the HIV infection rate of their babies is significantly lower than that of pregnant women in the placebo group without drug effects.
4, immune support therapy: one is to prevent HIV from combining with human cells, mostly anti-body type. It can be a surface antigen against the virus or an antibody against the T4 cell receptor, blocking the combination of the two, but only in the laboratory stage. The other is interferon, interleukin and other factors that affect the differentiation and growth of lymphocytes, but there is still a long way to go from practical application. The same is true of the recently proposed blood transfusion therapy.
