How does the body fight against AIDS?

How does the body fight against AIDS?

The immune system has many kinds of white blood cells to fight infections. HIV finds the white blood cells, called CD4 cells. HIV gets inside the CD4 cell and makes copies of itself. Then, HIV kills the CD4 cell and the new HIV copies find other CD4 cells to get inside and start the cycle again.

Which cells are destroyed in AIDS?

HIV infects and destroys certain white blood cells called CD4+ cells. If too many CD4+ cells are destroyed, the body can no longer defend itself against infection. The last stage of HIV infection is AIDS (acquired immunodeficiency syndrome).

Can AIDS be cured in early stages?

There is no cure for HIV yet. However, antiretroviral treatment (ART) can control HIV and allow people to live a long and healthy life. For some people, treatment can reduce the level of HIV in their body to such a low amount that they are unable to pass it on (known as having an undetectable viral load).

How can AIDS be treated or cured?

Currently, there’s no cure for HIV / AIDS . Once you have the infection, your body can’t get rid of it. However, there are many medications that can control HIV and prevent complications. These medications are called antiretroviral therapy (ART).

How does HIV affect the immune system over time?

Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These special cells help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body.

What happens in the acute stage of HIV infection?

In the acute stage of infection, HIV multiplies rapidly and spreads throughout the body. The virus attacks and destroys the infection-fighting CD4 cells of the immune system. During the acute HIV infection stage, the level of HIV in the blood is very high, which greatly increases the risk of HIV transmission.

Can a person with HIV get rid of it?

Unlike some other viruses, the human body can’t get rid of HIV completely, even with treatment. So once you get HIV, you have it for life. HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections.

How long does an HIV infection last in the body?

Within 2 to 4 weeks after infection with HIV, people may experience a flu-like illness, which may last for a few weeks. This is the body’s natural response to infection. When people have acute HIV infection, they have a large amount of virus in their blood and are very contagious.
