Transcript Understanding HIV and AIDS

•An infection in which
HIV enters the blood
and is multiplying in the
person’s cells.
• Helper T cells ~ white blood cells that
activate the immune response when a
pathogen enters the body.
•HIV attaches itself to helper T cells. The
virus forces the T cells to make copies of
the HIV, this is
•New viruses are released
from the T cells and they
attach to other cells.
The process of replication
then starts over.
Acquired
Immune
Deficiency
Syndrome
infections or illnesses that
take advantage of a
weakened immune
system.

count drops below
200.
