School Sores.

A highly contagious bacterial skin infection.

What are school sores?

School sores, a colloquialism for impetigois a very infectious superficial bacterial infection of the skin. Around 80-90% of infection is caused by “Gold Staph” (Staphylococcus Aureus). Streptococcus causes most of the other cases.

Six School Sore Snippets:

  • They are most common on the face and forearms/lower legs.
  • School sores are very common in kids – but also occur in adults (impetigo).
  • The condition is very contagious. Young children pass it to each other very readily.
  • Start treatment early for both ease of treatment and to get back to daycare/school/work as soon as possible.
  • Kids with eczema are more likely to get severe infection.
  • Recurrences can be caused by self-infection from staph carried in places like the nostril.

What do school sores look like?

There are two clinical types of school sores.

The Crusted type (non-bullous impetigo) accounts for 70% of cases. They start out as blisters or pustules that rupture. The crust is usually yellow, orange or brown in colour and can become quite thick as it accumulates.

The bullous type (bullous impetigo) accounts for 30% of cases. The lesions are eroded and red. They actually start as “bullae” which are large blisters but they burst almost as soon as they form. Look for the the edge of the blister just inside the rim of the lesion. The surface may be red, moist or covered in a thin honey-coloured crust. Classical bullous impetigo represents toxin produced by the Staph bacteria.
