What is a retrovirus?

A retrovirus is any of a group of viruses that contain two single-strand linear RNA molecules per virion, which means it carries its genetic blueprint in the form of ribonucleic acid (RNA) instead of deoxyribonucleic acid (DNA)। Additionally, the enzyme reverse transcriptase is employed to copy its genome into the DNA of the host cell's chromosomes. Usually the cellular process involves transcription of DNA into RNA. Reverse transcriptase makes it possible for genetic material to become permanently incorporated into the DNA genome of an infected cell.

What is the distinction between HIV and AIDS?

AIDS is a disease developed by a person living with HIV, which is a viral organism. The term AIDS applies to the most advanced stages of HIV infection. Although an HIV-positive test result does not mean that a person has AIDS, most people will develop AIDS as a result of their HIV infection.

There are four main stages in the progression of an HIV infected person developing AIDS. The period following the initial HIV infection is called the window period. It is called this because this period reflects the window of time between infection with the virus and when HIV antibodies develop in the bloodstream. An HIV test that looks for antibodies taken during this time can result in a false negative, though antibodies usually appear within six months of the initial infection.

Seroconversion refers to the period of time during which your body is busy producing HIV antibodies, trying to protect itself against the virus. This is the period after the initial infection when many people experience flu-like symptoms and swollen lymph nodes � this is a highly infectious stage.

After most people seroconvert, they usually experience a symptom-free period or asymptomatic period. This stage can last anywhere from 6 months to over 10 years, varying from person to person. Although the person with HIV is experiencing no symptoms, the virus is still replicating inside the body and weakening the immune system.

After this period, severe CD4+T cell loss leads to the symptomatic period, in which the body experiences the symptoms associated with HIV. This is the final stage before developing AIDS.
