Viral infection- Human immunodeficiency virus

Human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) Is may be a spectrum of situations generated by using infection with the (HIV).

HIV is a virulence disease that attacks cells within the immune system. The virus kills a sort of white blood cell within the immune system called a T-helper cell – additionally introduced as a CD4 cell – and utilizes those cells to produces copies of itself.

As HIV destroys more CD4 cells and makes more copies of itself, it continually weakens a person’s immune system. This means that someone who has HIV and isn’t taking treatment for it, will find it harder and more difficult to fight off infections and diseases.

If HIV is left untreated, it may take up to 10 or 15 years for the immune system to be so critically damaged that it can no longer defend itself. But, the rate at which HIV progresses varies depending on age, general health, and background.
