Antiretroviral Therapy (ART) are medications used for the treatment of HIV. The drugs do not cure or kill the virus. But, when these medicines are taken in combination form they actually help in the prevention of the growth of the virus. When the virus is slowed down, so is the HIV disease.

What is the HIV Life-Cycle?
There are several steps in the HIV life cycle including;
- Free virus circulation throughout the bloodstream.
- The HIV virus attacks the cell.
- The virus empties its content into the cell.
- The HIV genetic material i.e. RNA is used by the reverse transcriptase enzyme for the formation of the HIV DNA.
- The HIV DNA is injected into the cellâ€™s chromosome with the help of HIV integrase enzyme followed by HIV infection in the cell.
- When the infected cell reproduces, it activates the HIV DNA that helps in making the raw material for new HIV viruses.
- All the material for a new virus come together.
- The immature virus derived out of the infected cell through the process called budding.
- The immature virus bursts of the infected cell.
- The new virus matures, raw materials are cut with the help of protease enzyme and assembled into a functioning virus.
