What physical condition is Sinon said to suffer from, indicating his sin?

Sinon is described as suffering from a physical condition that signifies his sin, which is a "high fever." This ailment reflects the intense and burning guilt associated with his actions, particularly his role in deceit and betrayal during the Trojan War. High fever can symbolize the consuming nature of sin, representing the torment and suffering that comes from guilt and malicious deeds. In the context of Dante's Inferno, physical ailments often serve as metaphors for the spiritual sins that characters embody, and Sinon’s fever aligns with the theme of punishment that correlates with one's wrongdoing. His suffering also highlights the moral consequences of his dishonesty and treachery, emphasizing how sin can lead to both physical and spiritual affliction.
