The Exsurgent virus has horrific effects upon transhumanity. The documented effects of the Watts-MacLeod strain are only the beginning of what this virus can do to those whom it infects.

It is known, however, that those transformed by the Exsurgent virus are invariably changed to something other than transhuman. What, exactly, is unclear, although the effects of infection are horrifying to those who have observed it.
