Synopsis of Impetigo

Impetigo is a highly contagious bacterial skin infection, most common in children, but it can affect people of any age. It is usually caused by Staphylococcus aureus or Streptococcus pyogenes, and it spreads easily through direct contact, shared items (like towels or bedding), or open skin (e.g., insect bites, scrapes, eczema).

There are two main types:

  • Non-bullous impetigo (most common): Begins with red sores or blisters that quickly rupture, ooze fluid, and form a honey-colored crust.

  • Bullous impetigo: Features larger fluid-filled blisters that remain intact longer before bursting.

Typical symptoms include:

  • Red sores around the nose, mouth, hands, or legs

  • Itching or mild discomfort

  • Rapid spreading to nearby skin

  • Swollen lymph nodes (in some cases)

Impetigo is typically superficial but can lead to complications if untreated, such as cellulitis, kidney inflammation (post-streptococcal glomerulonephritis), or scarlet fever in rare cases.

When to see a doctor:
If sores are spreading quickly, accompanied by fever, or not improving in a few days, seek medical care. Diagnosis is clinical, and antibiotics (topical or oral) are often prescribed to prevent complications and transmission.

Natural remedies for Impetigo

Gently Clean the Area with Warm Water and Mild Soap: Keep sores clean and uncovered unless directed otherwise.

Apply Warm Compresses: Helps dry lesions and promote drainage.

Prevent Spread: Use separate towels, wash hands frequently, and trim nails to avoid scratching.

Boost Immunity with Rest and Hydration: Supports skin healing and microbial defense.

Disinfect Surfaces and Laundry: Reduce reinfection and transmission.
