Question

how hiv multiples in host body​

Answer 1

Answer:

The HIV lifecycle

HIV cannot reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it (joins together). It then takes control of the cell's DNA, makes copies of itself inside the cell, and finally releases more HIV into the blood.

Answer 2

Answer:

HIV infects white blood cells in the body’s immune system called T-helper cells (also called CD4 cells).

The HIV lifecycle refers to the different steps taken by the virus to make copies of itself.

First, the virus attaches itself to the T-helper cell; it then fuses with it, takes control of its DNA, creates copies of itself and releases more HIV into the blood.

Anti-HIV drugs target different stages in the HIV lifecycle, so knowing how HIV infects the body can help you to understand the different prevention and treatment options.

In this way, HIV weakens the body’s natural defences and over time severely damages the immune system. How quickly the virus develops depends on a person’s general health, how quickly they are diagnosed and start antiretroviral treatment, and how consistently they take their treatment.
