Impetigo

Christopher Hobbs:

“Impetigo is a bacterial skin infection often associated with Staphylococcus spp. or sometimes Streptococcus spp. The infection appears on the skin as red patches, then develops small white pustules which can join to form larger blisters. The infection is highly contagious and can occur commonly in small children and infants. This kind of infection can occur more readily in people who have a highly alkaline diet, such as a vegan diet or strict vegetarian diet.”

Etiologic and Other Factors Leading to Impetigo:

1. Etiologic Factors:
   Impetigo is primarily caused by bacterial infections, usually Staphylococcus aureus or Streptococcus pyogenes.
   • Risk Factors: Minor skin injuries (scratches, insect bites, eczema), poor hygiene, warm and humid climates, or contact with an infected person.
2. Other Contributing Factors:
   • Weakened immune system or pre-existing skin conditions.
   • Crowded living conditions or daycare environments (more common in children).
   • Seasonal prevalence (more common in summer and fall due to heat and humidity).

Signs to Seek Professional Help:

1. The infection spreads rapidly or becomes extensive.
2. Presence of fever or swollen lymph nodes.
3. Pain, redness, warmth, or pus around the lesions indicating deeper infection (e.g., cellulitis).
4. Lack of improvement with over-the-counter treatments or worsening of symptoms.
5. Infections near the eyes or sensitive areas.
