Expected: Disclosed in Consent Form or part of an underlying disease

Unexpected: More serious than expected or not disclosed in Consent Form

1. Mild Expected

  • Transient of minimal symptoms
  • No change in activity level
  • No therapy, or only symptomatic therapy, required

2. Mild Unexpected

  • Transient of minimal symptoms
  • No change in activity level
  • No therapy, or only symptomatic therapy, required

3. Moderate Expected

  • Symptomatic
  • Moderate change in activity level
  • Specific therapy required

4. Moderate Unexpected

  • Symptomatic
  • Moderate change in activity level
  • Specific therapy required

5. Severe Expected

  • Incapacitating = >24 hours of any of the following:
