- Another piece of good news is that, according to researchers' estimates, the VB variant's spread following the strain's emergence during the late 1980s and 1990s, and its more rapid dissemination in the 2000s, has been in decline since around 2010.
- The rate of CD4 cell decline, which is the hallmark of immune system damage by HIV, “occurred twice as fast in individuals with the VB variant, placing them at risk of developing AIDS much more rapidly.
