Scratching Bites: Keep fingernails short and clean. The bacteria streptococcal, which causes impetigo, hides under fingernails and enters the body when scratching the bite. Children are more vulnerable to this disease because streptococcal is often found in sand piles where kids play. Scratching the bite caused the hand to swell not the bug.
