What is infantigoWhat is Infantigo?

Infantigo gets its name from the Latin word impetere, which means ambush. The two bacteria’s namely, Streptococcus pyogenes and Staphylococcus aureus are responsible for this infection.

Also known as school sores characterized by the patch of red, itchy skin sores which burst and develop honey-colored crusts.

In 2010, Infantigo influenced about 2% of the population, i.e., approximately 140 million people.

Types of Infantigo and their Symptoms

Impetigo can be of two kinds: Bullous and Non-Bullous Impetigo.

Bullous Impetigo

The bacteria Staphylococcus produces Exfoliative toxin A, which reduces adhesion, between uppermost layer (epidermis) and the lower layer(dermis) of the skin.

This condition is known as Bullous Impetigo.

  • Characteristically found in the newborn.
  • It can occur around the neck, diaper or axilla region.
  • Some of the symptoms might include itching, swelling of nearby glands, fever or diarrhea. A kidney disease could occur as a result of the long-term effect of impetigo.
  • The disease is no more contagious after two days if the infected person is on proper antibiotic medication.

Non-bullous Impetigo or Infantigo contagiosa or school sores can occur due to both, Streptococcus or Staphylococcus.

  • It can be experienced at any age but is most common in children.
  • Its first symptom can be a red sore close to the nose or mouth that later take the shape of yellowish crusts on the face, arms or legs.
  • Skin ulcers or redness may also come out as a result of scratching the skin. Fever is not very common, but lesions can be itchy or painful.
  • People get better within three weeks without getting themselves treated.


Either of both Streptococcus pyogenes and Staphylococcus aureus can cause Ecthyma.

Sometimes, prolonged bullous or non- bullous impetigo might also result in Ecthyma. It digs deeper into the skin and is more severe than any other form of Infantigo.

  • Some small, pus-filled sores with a thick crust and surrounded by reddish-purple skin is how it is recognized. Most often, it appears on buttocks, thighs, ankles, and feet.
  • Ecthyma blisters can be painful.
  • Blisters heal slowly and may also leave scars.

Causes of Impetigo

Besides the two causative bacteria’s, Streptococcus and Staphylococcus it is not precisely known why this ailment appears.

Some people have a high tendency of resisting impetigo because of their general good health or due to some chemicals applied on their skin. But observation reveals a few of the following causes may act as triggers to Impetigo.

  • Already infected skin- Skin which has some other infections is easily affected. But it is not that it cannot develop in the healthy skin.
  • Open wounds, injuries, cut, scratch or rashes to inhibit this skin disorder in a child.
  • Warm and humid environment.
  • Contact – As it is a contagious infection, it spreads quickly and easily through close contact. Within ten days the blisters would be visible after the bacteria injects into your skin.

Is Impetigo Contagious?

The answer to this would obviously be yes. It is a contagious bacterial skin infection.

A person infected with Infantigo can pass on the virus to an uninfected person through close contact. One needs to stay at home at least until the time up to which it is no more infectious.

Without antibiotics, it is contagious until the time, until the sores heal.

Infantigo in Adults

How does Infantigo Spread?

Most people carry the causing bacteria’s in their nose. Though it can also cause throat infections, Infantigo spreads through a person infected with it or being in contact with the carrier of the bacteria.

The virus transmits through direct(close) or indirect intermediary. A person with open wounds or cuts has a low resistivity against this disease. After the rash is dry, the bacteria are not infectious to the intact skin.

How is Infantigo Diagnosed?

The diagnosis of Infantigo is essential to take necessary precautions to prevent it from spreading. The doctor would be able to diagnose Impetigo just by looking at your or your child’s skin. He may also ask about recent cuts, rashes, allergies, etc.
