“Everyone has a “CD4 count” —the number of white blood cells in your body. Because this is what HIV attacks, it’s common for someone living with the virus to have a lower number than normal. The lower it is the weaker the immune system. A count below 200 is considered the final stage of HIV progression, known as AIDS. Taking daily A.R.V.s keeps counts high, immune systems strong, and hinders progression. Share this info! KNOW HIV=NO HIV”
