Types of Skin Infections in Pediatric Patients

1. Bacterial Skin Infections

Caused by bacteria, mainly Staphylococcus aureus and Streptococcus pyogenes.

Impetigo
  • Highly contagious, common in toddlers and preschoolers.
  • Symptoms:
    • Red sores that break open and form honey-colored crusts (often around the mouth and nose).
  • Treatment:
    • Topical or oral antibiotics (e.g., mupirocin, cephalexin).
    • Keep affected areas clean and covered.
Cellulitis
  • Deeper bacterial infection affecting the skin and underlying tissues.
  • Symptoms:
    • Red, warm, swollen skin with tenderness.
    • Fever and chills in severe cases.
  • Treatment:
    • Oral or IV antibiotics, depending on severity.
    • Monitor for spreading redness, as it may indicate worsening infection.
Boils (Furuncles) & Abscesses
  • Painful, pus-filled lumps caused by bacterial infections in hair follicles.
  • Treatment:
    • Warm compresses to help drainage.
    • Larger boils may need drainage by a doctor.
    • Antibiotics if severe or recurrent.

2. Viral Skin Infections

Caused by viruses, often self-limiting but can be contagious.

Molluscum Contagiosum
  • Caused by the molluscum contagiosum virus (poxvirus family).
  • Symptoms:
    • Small, flesh-colored, dome-shaped bumps with a central dimple.
    • May spread through skin contact or shared items.
  • Treatment:
    • Often resolves on its own in 6–12 months.
    • Cantharidin (“beetle juice”) or cryotherapy may be used for removal.
Hand, Foot, and Mouth Disease (HFMD)
  • Caused by Coxsackievirus.
  • Symptoms:
    • Fever, sore throat, followed by painful mouth sores.
    • Red spots or blisters on the hands, feet, and diaper area.
  • Treatment:
    • Supportive care with hydration and pain relief (acetaminophen, ibuprofen).
    • Hand hygiene to prevent spread.
Herpes Simplex Virus (HSV) – Cold Sores
  • Painful blisters around the lips or mouth.
  • Triggered by stress, fever, or sun exposure.
  • Treatment:
    • Antiviral creams or oral antivirals (acyclovir) if severe.

3. Fungal Skin Infections

Caused by fungi, usually affecting warm, moist areas of the body.

Ringworm (Tinea)
  • Caused by dermatophyte fungi (Tinea species).
  • Symptoms:
    • Circular, scaly, red patches with a clear center.
    • Can affect the scalp, body, feet (athlete’s foot), or groin (jock itch).
  • Treatment:
    • Topical antifungal creams (clotrimazole, terbinafine).
    • Oral antifungals for scalp infections (griseofulvin, terbinafine).
Candida (Yeast) Infections
  • Common in diaper areas and skin folds.
  • Symptoms:
    • Bright red rash with satellite lesions (small red bumps around the main rash).
    • May occur after antibiotic use.
  • Treatment:
    • Topical antifungal creams (nystatin, clotrimazole).
    • Keep the area dry and clean.

4. Parasitic Skin Infections

Caused by tiny parasites that live on or in the skin.

Scabies
  • Caused by the Sarcoptes scabiei mite.
  • Symptoms:
    • Intense itching, especially at night.
    • Red, pimple-like rash between fingers, wrists, elbows, and diaper area.
  • Treatment:
    • Permethrin cream (apply from neck down, leave overnight).
    • Treat all household contacts to prevent reinfection.
Head Lice (Pediculosis Capitis)
  • Tiny lice infest the scalp and lay eggs (nits) on hair shafts.
  • Symptoms:
    • Itchy scalp, visible lice or nits.
  • Treatment:
    • Lice shampoos (permethrin, malathion) and nit combing.
    • Wash bedding, clothes, and hair accessories.
When to See a Doctor

Seek medical attention if:

  • The rash or infection worsens or spreads despite treatment.
  • The child develops fever, pain, or swelling.
  • There is pus, drainage, or red streaks around the rash.
  • The infection keeps coming back.
