Staphylococcal impetigo

What is Staphylococcal Impetigo?

Staphylococcal impetigo is a highly contagious bacterial skin infection caused by staphylococcus aureus (staph). It most commonly affects children ages 2 to 5 years old, and it occurs when the bacteria comes into contact with a cut, scrape, or bug bite in the skin. It starts off with small blisters, and then they turn into honey-colored crusts.

The main symptom of staph impetigo is the development of red sores, blisters, or pus-filled bumps that can itch or burn. The sores can be on the face, hands, or other parts of the body. They may become crusted or scabbed over and can spread quickly, particularly in a household of multiple children.

Diagnosis and Treatment

The doctor will usually make a diagnosis of staph impetigo based on its characteristic symptoms and appearance. A skin sample or culture may be taken to confirm the diagnosis. Oral antibiotics or antibacterial creams are typically used to treat impetigo, although more severe cases may require administered in hospitals.


If a child has impetigo, it is important to have them tested for other serious infections, such as group A streptococcus. It is also important to keep the area clean and covered and to practice good hygiene. If children are using topical creams or ointments, they must wash their hands thoroughly with soap and warm water before and after applying the treatment.

  • Clean any affected areas with an antiseptic liquid or cream.
  • Keep the areacovered to reduce the risk of spread.
  • Clean any previously infected areas again.
  • Wash any items that have come into contact with the infected area in hot, soapy water.
  • Discard any items that can't be cleaned.
  • Encourage frequent hand washing.
