AIDS, also known as acquired immunodeficiency syndrome, is mainly transmitted through humoral communication. AIDS can not be cured now
biggest dildo best vibrator , for parents who want to prepare for pregnancy, if there is AIDS on the one hand, the possibility of transmission between spouses is very high, and eventually the fetus is infected with AIDS, we must pay attention to it. AIDS, also known as acquired immunodeficiency syndrome (AIDS), is an infectious disease 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.
Interpretation of the process of AIDS
Two kinds of glycoproteins, gp120 and gp41, are embedded in the lipoprotein membrane of HIV in vitro. Gp120 has affinity with CD4 glycoprotein on the surface of lymphocytes, and gp41, which specifically binds to it, can mediate the fusion of virus membrane and host cell membrane. Therefore, HIV can reach the blood through other methods such as skin and mucous membrane damage and blood, 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
male masturbators , causing viremia, the expression of shell antigen p24, 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.
However, HIV was not completely killed and entered a state of persistent latent infection. HIV was in a low-level replication and the clinical manifestation was asymptomatic HIV infection. With the continuous replication and spread of HIV, CD4+ lymphocytes continue to die, which leads to the depletion of CD4+ lymphocytes, serious destruction of immune function, infection of various conditional pathogenic bacteria and tumors, clinical manifestations of AIDS, and finally death.
Follow the ABC principle and stay away from AIDS
Sexual activities are an important part of human life, but sexual activities bring happiness to human beings, help human reproduction, and bring a lot of troubles to human beings, including the spread of AIDS and sexually transmitted diseases. In recent years, on the basis of summarizing the experience of disease prevention and AIDS prevention, some foreign experts put forward the ABC principle of disease prevention and AIDS prevention.
A:Abstinence abstinence
The A here is the first letter of Abstinence (abstinence), that is to say, if people do not have sex, the risk of contracting STDs and AIDS will be greatly reduced. Only when teenagers master the knowledge of preventive diseases and AIDS, learn to regulate sexual impulses and abide by social moral standards, can they avoid being rashly involved in dangerous activities and causing harm to themselves and others.
B:Befaithful loyalty
The b in the ABC principle is the first letter of Befaithful (faithful person) in English, which means loyalty to both husband and wife and sexual partnership to those who cannot abstain from abstinence. Having sex with many people is an important way to spread STD and AIDS. The more people who come into contact with people in sexual activities, the greater the risk of patients.
C:Condom condom
If points an and b are not reached, c (the first letter of English condom Condom) can use condoms correctly and reduce the risk of infectious diseases and AIDS.
People have put forward the ABC principles for the prevention of STDs and AIDS, of which principles an and b are the safest, but not everyone can do them, so condoms are the last protective barrier provided by their own people.
On condom prevention of AIDS and venereal diseases
(1) sexual intercourse with condoms can significantly reduce the chance of contracting AIDS and STDs, but condoms are not 100% safe. Because if the skin of the uncovered part of the condom is damaged, it may be infected with STD and AIDS.
(2) improper use or poor quality of condoms will also affect the effect of disease prevention.
