The grading of these scorpion envenomations depends on whether or not neurological signs predominate and is as follows:

Nonneurological predominance is graded as follows [2] :

  • Mild - Local signs of erythema, swelling and tenderness (estimated 68.6%)

  • Moderate - Ascending local signs or mild systemic signs (estimated 26.8%)

  • Severe - Life-threatening systemic signs (estimated 4.6%)
