Why is resisting the urge to scratch a bite site important?
Answer
To prevent secondary bacterial infection that can complicate healing
While itching can be a symptom following a spider bite, intentionally scratching the affected area introduces a significant risk of complications. Breaking the skin barrier through scratching allows common environmental bacteria to enter the wound. This inoculation can lead to a secondary bacterial infection, which is entirely separate from the initial venom effects, potentially complicating the healing process significantly, necessitating additional treatment such as antibiotics, and delaying the resolution of the bite site.
