Differential Diagnosis for a Great Dog Bite
- Single most likely diagnosis:
- Rabies: This is a significant concern with any animal bite, especially from dogs, as rabies can be fatal if not treated promptly.
- Other Likely diagnoses:
- Infection (e.g., Pasteurella, Streptococcus, Staphylococcus): Dog bites can introduce bacteria into the wound, leading to infection.
- Soft tissue injury: Lacerations, puncture wounds, or crush injuries can occur from dog bites.
- Tetanus: If the victim's tetanus vaccination is not up to date, a dog bite could lead to tetanus infection.
- Do Not Miss diagnoses:
- Capnocytophaga infection: Although rare, this bacterial infection can be severe and even life-threatening, especially in individuals with compromised immune systems.
- Rabies (again, due to its severity and the importance of prompt treatment): Even though listed as the most likely, its potential severity warrants a second mention here.
- Rare diagnoses:
- Erysipeloid: A rare bacterial infection that can be transmitted through animal bites, characterized by a distinctive rash.
- Actinomycosis: A rare chronic bacterial infection that can be introduced through deep wounds, including animal bites.
