Cellulitis: The Skin Infection You Need to Know About
Published: Oct 22, 2023
Cellulitis is a common but potentially serious skin infection that affects deeper layers of skin. It can spread quickly and even become life-threatening if not treated promptly.
What Causes Cellulitis?
Cellulitis occurs when bacteria, usually streptococcus or staphylococcus, enter through a break in the skin. Common entry points include cuts, scrapes, burns, insect bites, or surgical wounds. People with weakened immune systems, diabetes, or poor circulation are at higher risk for developing cellulitis.
Recognizing the Symptoms
The infected area typically becomes red, swollen, warm, and tender to touch. Unlike erysipelas, which has clearly defined raised borders, cellulitis has less distinct edges. Other symptoms may include fever, chills, and swollen lymph nodes. If you notice these signs, especially if they're spreading rapidly, seek medical attention immediately.
Treatment Options
Antibiotics are the primary treatment for cellulitis. For mild cases, oral antibiotics like dicloxacillin or cephalexin may be prescribed. More severe cases may require intravenous antibiotics in a hospital setting. It's crucial to complete the entire course of antibiotics, even if symptoms improve, to prevent recurrence or antibiotic resistance.
Frequently Asked Questions

Typically 5-14 days, depending on severity.

The Bottom Line
