          -  Agrees to collection of required specimens

          -  Agrees to report any adverse events for the duration of the protocol

          -  • Has known intolerance to ribavirin.

               -  Is irreversibly ill on presentation, as defined by presence of profound shock
                  (shock which does not respond to supportive therapy within 3 hours after

                  initiation of IV ribavirin

               -  Has history of hemoglobinopathies (ie, sickle-cell anemia or thalassemia major).

               -  Has history of autoimmune hepatitis.

               -  Has serum calculated creatinine clearance of < 30 mL/min.

                  pacemaker and no capability of a pacemaker placement or Wolfe-Parkinson-White

               -  A sinus bradycardia of less than 40 beats per minute (see below).

               -  Is currently being treated with didanosine (ddI). ddI must be discontinued before

             treatment with IV ribavirin versus no ribavirin treatment for CCHF (generally
             associated with high mortality) and severe cases of Lassa fever (high mortality rates)
             versus mild cases of Lassa fever (low mortality rates).

          -  A New York Heart Association cardiac functional capacity of Class II or greater for
             atherosclerotic heart disease (ASHD) and congestive heart failure (CHF).

          -  Known cardiac defects that may predispose the subject to bradyarrhythmias, such as
             second or third degree heart block or sick sinus syndrome without a pacemaker, but
             capability of pacemaker placement, if needed.

          -  Sinus bradycardia of 41-49 beats per minutes, if the individual is not known to have a
             low resting heart rate related to physical conditioning.
