Log
This mathematical term represents a change in value of what
is being measured by a factor of 10. Changes in viral load (the
amount of HIV in the blood) are often reported as logarithmic
or log changes. For example, if the viral load is 20,000 copies/
mL, then a 1-log increase equals a 10-fold (10 times) increase, or
200,000 copies/mL. A 2-log increase equals a 100-fold increase, or
2,000,000 copies/mL.
Long-Term Nonprogressors
People who have been infected with HIV for a number of years
(usually at least 7) but who have had stable CD4 cell counts of 600
L
cells/mL or more, no HIV-related diseases, and no need for anti-HIV
therapy.
Lumbar Puncture
See: Spinal Tap
Lymph
A clear, slightly yellow fluid that carries disease-fighting white blood
cells from the blood to and from body tissues.
Lymphadenopathy Syndrome (LAS)

from infection, such as HIV, the flu, or mononucleosis, to lymphoma
(cancer of the lymphoid tissue).
