HIV infection goes into its second stage, which can be a long period without symptoms, called the asymptomatic (or latent) period. This is when people may not know they are infected and can pass HIV on to others. This period can last 10 or more years. During this period without symptoms, HIV is slowly killing the CD4 T-cells and destroying the immune system. Blood tests during this time can reveal the number of these CD4 T-cells. Normally, a person has a CD4 T-cell count between 450 and 1,400 cells per microliter.
