Skin Infections – What They Are and How to Handle Them
If you’ve ever had a red, itchy bump that didn’t go away, you probably dealt with a skin infection. These infections can be caused by bacteria, fungi, or even an allergic reaction to something you touch. The good news is most of them are easy to spot and treat if you act fast.
Common Types of Skin Infections
Bacterial infections like cellulitis, impetigo, and folliculitis start when germs get into a cut or scrape. You’ll notice swelling, warmth, pain, and sometimes pus. If the infection spreads quickly or you develop a fever, see a doctor right away.
Fungal infections love warm, moist places. Athlete’s foot, ringworm, and yeast overgrowth cause itching, scaling, and ring‑shaped rashes. They’re not dangerous but can be stubborn if you don’t keep the area dry and clean.
Contact dermatitis isn’t caused by germs; it’s an allergic reaction to something that touches your skin—think nickel jewelry, certain soaps, or plant oils. The rash is red, itchy, and may blister. Removing the irritant usually clears it up fast.
How to Manage and Prevent Skin Infections
The first step is hygiene. Wash any wound with mild soap and water, then cover it with a clean bandage. Change the dressing daily and watch for signs of infection—redness that spreads, increasing pain, or foul‑smelling discharge.
For fungal problems, keep affected areas dry. Use an over‑the‑counter antifungal cream twice a day for two weeks, even if the rash looks better after a few days. This prevents it from coming back.
If you suspect contact dermatitis, identify the trigger and stop using it. A gentle moisturizer can soothe the skin, and a short course of hydrocortisone cream helps reduce inflammation.
When to see a doctor? If you have any of these red flags: fever over 100.4°F (38°C), swelling that’s getting bigger, pus that won’t stop draining, or an infection on your face, hands, or genitals. A professional can prescribe antibiotics for bacterial infections or stronger antifungals if needed.
Prevention is mostly about protection. Wear gloves when handling chemicals or plants, choose hypoallergenic jewelry, and keep cuts covered until they heal. For athletes, wear breathable shoes and change socks often to stop fungal growth.
Remember, most skin infections are minor, but catching them early makes treatment easier. Keep an eye on your skin, practice good hygiene, and don’t ignore a worsening rash—your skin will thank you.
