AIDS and HIV are not the same thing. However Having HIV leads to AIDS.

AIDS

 


HIV


HIV is a retrovirus. Meaning it contains RNA instead of DNA.

The reason HIV is so deadly is because it affects T4 lymphocytes (A form of T helper cell), thus directly affecting your immune system.

Essentially they are killing the police officers of the immune system.

Helper T cells contain specific receptors on their surface which identify them as helper T cells. These are called CD4 receptors.

HIV has specific receptors which bind to the CD4 receptors.

Once HIV attaches onto the T lymphocyte it is absorbed into the cell.

A capsule containing Viral RNA, reverse transcriptase and other enzymes is released into the cell.

Once inside, reverse transcriptase goes to work, turning viral RNA into signal stranded DNA, using the host cells nucleotides.

During this process random errors are made (mutations).

The single stranded DNA is then turned into double stranded DNA.

The new viral DNA is taken into the cell’s nucleus and inserted into the host cells DNA.

This Causes the cell to create new HIV parts.

The newly created viral RNA strands and enzymes are packaged in a protein capsule.

New HIV bud off the host cell, with a combination of host and viral proteins. These viruses mature and attack other T4 lymphocytes.

AIDS develops as a result of HIV. Once infected with HIV your immune system is severely compromised meaning you can’t fight off simple infections.

Individuals with HIV don’t always develop AIDS. AIDS occurs in the final stages of HIV, at this stage individuals have a badly damaged immune system.

AIDS puts individuals at risk of Opportunistic infections (Ois). Simple infections which a healthy immune system could fight can now cause server damage and eventually death.

You can have HIV with out AID, however not can not have AIDS without HIV.
