Retraction Note: Severe Viperidae envenomation complicated by a state of shock, acute kidney injury, and gangrene presenting late at the emergency department: a case report.

The authors have retracted this case report [1] because the head of the snake shown in Figure 1 and described as being that of a viper (Echis occellatus) is identical to the head of a snake shown in Figure 1 of a different case report [2] where it was identified as being Naja melanoleuca, a member of the Elapidae family.
