Answer

The toxicity, variation, and duration of the symptoms depends on the following factors:

  • Scorpion species

  • Scorpion age, size, and nutritional status

  • Healthiness of the scorpion's stinging apparatus (telson)

  • Number of stings and quantity of venom injected

  • Depth of the sting penetration

  • Composition of the venom

  • Site of envenomation: Closer proximity of the sting to the head and torso results in quicker venom absorption into the central circulation and a quicker onset of symptoms.

  • Age of the victim, as children are more susceptible to severe clinical manifestations

  • Health of the victim

  • Weight of the victim relative to amount of venom

  • Presence of comorbidities

  • Treatment effectiveness
