The human immunodeficiency virus (HIV)
seeks and destroys CD4+ cells, a type of T lymphocyte (T cell). T cells are
critical to the immune system. They’re responsible for warding off diseases and
most infections, including viral infections.
HIV targets the type of cells that would
normally fight off an invader like HIV. As the virus replicates, it damages or
destroys the infected CD4+ cell and produces more virus to infect more CD4+ cells.
Without treatment, this cycle continues in most infected people until the
immune system is badly compromised, leaving them open to many serious
infections and illnesses. Many of the illnesses that people compromised immune
systems get are rare in people with functioning immune systems.
How quickly the virus progresses varies
from person to person. Factors like your age, overall health, and how quickly
you’re diagnosed and treated can make a difference.
Acquired immunodeficiency syndrome
(AIDS) is the final stage of HIV. At this stage, the immune system is severely
weakened, and the risk of contracting opportunistic infections is much greater.
Not everyone with HIV will go on to develop AIDS.
Importantly, many of the effects
described here are related to the failure of the immune system in progressing
HIV and AIDS. Many of these effects are preventable with early antiretroviral
treatment, which can preserve the immune system. However, for anyone without
access to effective antiretroviral treatment, these effects remain
possible.
