t know what herpes expert you are talking about, but starting Famvir at day 14 after contact would have absolutely no impact on contracting
herpes. If you had come in direct contact with
herpes and had taken the
Famvir within an hour or two for several days, then maybe, yes.
Yes, a western blot at 16 weeks would be conclusive but will likely not be different than results now. The western blot picks up more HSV 1 than the ELISA does.
