To help prevent cellulitis:
Prevent skin injury — Wear protective gloves while gardening and working outdoors. Wear long sleeves and trousers while hiking. Avoid going barefoot outdoors. Wear protective padding on elbows and knees while skating.
Treat minor skin wounds promptly — Gently wipe away dirt, wash with antibiotic soap, apply antibiotic ointment and cover with a clean bandage.
Seek medical attention — Medical attention is needed for all deep puncture wounds and animal bites and for all deep wounds involving a joint, hand or foot.
