• Impetigo is a highly communicable skin
  infection that mostly affects the children, but
  can also occur in adults. Impetigo is also known
  as Infantigo. Children between the ages of 2-5
  years are at greater risk of developing impetigo.
  Impetigo results in the formation of red, itchy
  sores that can occur anywhere in the body.
  Impetigo can easily spread from an infected
  person to a healthy person.

Types of Impetigo

• Ecthyma- This is a more severe form of Impetigo
  as it affects deeper layers of the skin. There
  are extremely painful boils that may develop into
  open sores. Impetigo contagiosa- This is the
  most contagious and common type of Impetigo in
  children. The lumps in this type are very itchy,
  but may not be painful. Bullous Impetigo- This
  form of impetigo is common among the children
  under the age of two. The red and itchy lumps
  generally appear on the arms and legs.

Causes of Impetigo 

• The bacteria Staphylococcus aureus and
  streptococcus pygoenes are cause impetigo. These
  bacteria enter the body through a cut or a wound.
  Sometimes impetigo is caused as a result of
  already present skin infection such
  as dermatitis. A healthy person becomes infected
  by coming in direct contact with the blister or
  using infected persons items such as towel,
  sheets, or a razor. Insect bites or animal bites
  can also result in the development of this skin
  infection.

Diagnosis of Impetigo 

• A dermatologist usually diagnoses Impetigo by
  looking at it. Tell your doctor about the
  symptoms you have been experiencing. A doctor may
  also take a pus sample from the Impetigo. This
  sample is observed in the lab to determine
  causative agent. The reports of the lab test will
  help in determining the suitable treatment of
  Impetigo.

Treatments

• The goal of the treatment of Impetigo is to
  prevent the infection from spreading further and
  reverse the affect of unfavourable scarring. The
  mild symptoms of Impetigo are easily treatable by
  taking hygienic measures. For the treatment of
  mild symptoms, a dermatologist may prescribe
  antibacterial ointment which should be applied
  directly onto the affected area. Oral medications
  are given to a patient with Impetigo. This oral
  medicine prevents the infection from developing
  into the blood. It is also recommended to wash
  affected areas with antibacterial soap. Avoid
  touching affected area and always wash hands
  before eating anything and after using the
  bathroom.
