CD4% – percentage of total lymphocytes (white blood cells) that are CD4 cells.
The CD4% is generally more stable than the CD4 count. For example, if you ever get a CD4 count that is much lower than you expect, first see whether the CD4% has changed too,
If the CD4% is still roughly the same then the low CD4 count is unlikely to show a real change.
duration – how long in time.
malignant – dangerous. A malignant cancer is a dangerous cancer that is growing.
treatment-naive – someone who has never taken any anti-HIV treatments before. (Note: people who are treatment naive can still be resistant to anti-HIV drugs if they were infected with a drug resistant strain of HIV}.
HSV – Herpes Simplex Virus. HSV-1 is the virus mainly associated with cold sores on your lips or faces. HSV-2 is the virus mainly associated with genital herpes. The viruses are very similar.
