Explanation:
- **TragedyDegree (3):** The story contains elements of tension and urgency due to the emergence of a new, potentially dangerous virus. However, it does not feature significant personal loss, widespread devastation, or profound emotional setbacks typically associated with higher tragedy scores. 
- **ComedyDegree (3):** The narrative has a positive resolution, with the scientists successfully developing a treatment, but it lacks overt comedic elements or a particularly light-hearted tone. The triumphant moment at the end provides a sense of relief and hope rather than strong comedic delight.
