How does the body respond to HIV?
HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.
What does HIV do to the body before showing symptoms?
Within 2 to 4 weeks after infection with HIV, about two-thirds of people will have a flu-like illness. This is the body's natural response to HIV infection. Flu-like symptoms can include: Fever.
How does the body respond to HIV?
The body responds by producing HIV antibodies and killer T- cells which are special lymphocytes that seek out and destroy invading pathogens such as viruses and bacteria . Two to four weeks after infection, the immune system launches an attack against HIV using these antibodies and killer T-cells, significantly reducing HIV level on blood. A percentage of the viruses however escapes this onslaught by hiding in other cells and continue to multiply.
What is the first stage of HIV?
The acute stage is known as the first stage of HIV infection. The body responds by producing special lymphocytes that search out and destroy invasive pathogens such as viruses and bacteria by producing HIV antibodies and killer T- cells. Using these antibodies and killer T-cells, the immune system launches an attack against HIV two to four weeks after infection, dramatically reducing HIV levels in the blood. However, by hiding in other cells, a proportion of the viruses avoid this attack and begin to multiply.
What is the effect of HIV on the body?
What effect does HIV have on the body? HIV attacks a specific type of immune system cell in the body. It’s known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections.

During this time, the virus is multiplying rapidly in the body, unchecked. This initial HIV stage can result in flu-like symptoms.
Why does HIV attack CD4 cells?
This is because the body has difficulty responding to new infections. Not only does HIV attack CD4 cells, it also uses the cells to make more of the virus. HIV destroys CD4 cells by using their replication machinery to create new copies of the virus. This ultimately causes the CD4 cells to swell and burst.

How does HIV affect the body?
HIV primarily affects the body by targeting and damaging cells in the immune system. The immune system protects the body against viruses, bacteria, and fungi. After attaching itself to a type of white blood cell called a CD4 T cell, the virus merges with it. These T cells are an important part of the immune system.
