I. Introduction
The human immunodeficiency virus (HIV) is a virus capable of attacking the body's immune system. Since it was first identified in the early 80s, HIV AIDS has become a global public health challenge. The purpose of this article is to intuitively and vividly reveal the whole process of HIV infection in the human body in the form of a series of comics, in order to help readers have a deeper understanding of the virus, raise awareness of prevention, and share personal experience after reading.
2. The whole process of HIV virus invasion of the human body
1. Initial contact
The HIV virus is transmitted through blood, milk and other bodily fluids. When HIV-containing bodily fluids enter the body, the virus begins to look for its invasion portal – CD4+ T cells.
2. Viral infection
Glycoproteins on the surface of the HIV virus bind to receptors on CD4+ T cells, allowing the virus to enter the cell's interior. Subsequently, the virus sheds its outer shell and releases the RNA genome.
3. Virus replication
The RNA genome of the HIV virus is converted to DNA by reverse transcriptase and integrated into the genome of the host cell. These DNA then instruct the cell to make more viral RNA and proteins, which eventually assemble into new viral particles.
4. Virus release and spread
How newly generated viral particles are released from infected CD4+ T cells and infect more cells. This process is constantly repeated, resulting in a rapid increase in the number of viruses in the body.
5. Impaired immune system
As the number of viruses increases, more and more CD4+ T cells become infected and die. HIV infection causes severe damage to the immune system.
6. Disease development
People living with HIV go from the initial asymptomatic period, to the symptoms of various opportunistic infections, and eventually to AIDS. This process can take years or even decades, but once AIDS develops, the patient's quality of life is severely reduced, and the life expectancy is severely affected.
3. Experience after reading
We were able to get a glimpse of the rampant behavior of the HIV virus in the human body and feel the ruthless destruction of the human immune system. This process not only reveals how HIV is transmitted and pathogenesis, but also reminds us of the importance of preventing HIV infection.
First, we should recognize that HIV infection is not a distant disease. It can be transmitted through a variety of bodily fluids such as blood, breast milk, etc., which means that we must always be vigilant in our daily lives to avoid high-risk behaviors. At the same time, we should also understand that not all people living with HIV are "dangerous" or "scary", they are also victims of the disease and need the care and support of society.
Second, we should focus on the prevention of HIV AIDS. Prevention is the most effective means of controlling HIV transmission. We should actively promote safe sex, reduce unnecessary blood transfusions and injections, and avoid sharing personal items such as syringes and knives with people living with HIV to reduce the risk of infection. In addition, we should strengthen publicity and education on HIV AIDS, raise public awareness of the disease, and eliminate discrimination and prejudice against people living with HIV.
Finally, we should pay attention to the ** and care of people living with HIV. With the development of medicine, people living with HIV can already control viral replication, prolong life and improve quality of life through drugs**. We should support them to actively accept**, help them reintegrate into society, and reduce their psychological burden. At the same time, we should also advocate for all sectors of society to pay attention to the rights and interests of people living with HIV, and provide them with more care and support.
Through this article, we have a deeper understanding of the whole process of HIV infection in the human body. This makes us deeply aware of the seriousness and dangers of HIV AIDS, and reminds us that we must strengthen our awareness of preparedness and jointly address this global public health challenge. Let's work together to create a better future without HIV aids!
