Summary Introduction

Introduction:

HIV belongs to the retroviruses family, all of which contains the RNA genome. The virus attaches and penetrates T cells of the human that play an essential role in the immunity of a person. Infected cells express the viral genes and produce new viruses which in turn infect other T cells leading to a decrease in the population of T cells. Eventually, loss of T cells results in a decline in the immune system of the body for other diseases as well.
