Cellulitis is a bacterial infection affecting the deeper layers of the skin, including the dermis and subcutaneous tissue. It presents as a tender, red, and warm area, sometimes accompanied by swelling and fever. While it can occur anywhere on the body, the legs are the most commonly affected.
Causes and Risk Factors
Cellulitis typically results from bacteria entering the skin through breaks or cracks. The most common culprits are Group A Streptococcus and Staphylococcus aureus. Risk factors include:
- Existing skin conditions like athlete's foot or eczema
- Recent injuries, cuts, or surgical wounds
- Weakened immune system
- Chronic conditions such as diabetes or poor circulation Diagnosis
Diagnosis
Diagnosis is primarily based on clinical examination, considering the characteristic signs and symptoms. In some cases, additional tests like blood cultures or imaging may be necessary to rule out other conditions or identify the causative bacteria.
Treatment
Treatment usually involves antibiotics to eliminate the infection. The choice of antibiotic depends on the suspected bacteria and local resistance patterns. It's essential to complete the full course of antibiotics as prescribed. Elevating the affected area and applying warm compresses can help alleviate pain and swelling. In cases where an abscess forms, surgical drainage may be required.
Prevention
Preventing cellulitis includes practicing good skin hygiene, promptly cleaning and caring for cuts or abrasions, and managing chronic conditions effectively. For individuals with recurrent episodes, a healthcare provider may recommend preventive antibiotics.
