Causes of Infantigo

The following are the causes to develop infantigo

Skin Injury

Any cut, animal or insect bites, allows the streptococcal bacteria to enter in the dermis layer of the skin and multiply there. Inflammation occurs at the site of infection due vasodilatation. Poor hygiene, delay wound healing in case of diabetic patient or immune system disorder trigger the progression of infantigo.

Skin Diseases

Allergy, rashes, eczema are the common skin diseases and these are triggered in warm weather. Untreated chronic skin diseases cause infentigo.

Direct Skin Contact

Infentigo is a contagious disease, direct contact with an infected person transmit the infection. Living in overcrowded areas, activities need direct skin contacts, school going children, scratching the infection cause spreading of infection.

The initial symptoms arise after 4-10 days of the entrance of the bacteria. This period is known as the incubation period. After invading into the skin, the Staphylococcus generates infantigo toxin and bound to surrounded skin proteins and affect the skin cells. The degenerative condition is progressing inside the skin and symptoms occur.

Treatment of Infantigo

For treatment of infantigo, it is important to start with proper diagnosis. Sometimes misunderstanding is created with other skin disease like ring worm or other fungal infection.

After diagnosis, dermatologist initiates the treatment with cleaning the sores with swab. They recommended that maintenance of proper hygiene of the sore at home also.

This helps to restrict the growth of the bacteria and restrict spreading of infection.

In case of non bullous type of infection, usually the pimples are burst rapidly and the secretion is dry fast. Usually simple washing is not useful to remove the coating. It is advisable to soak the wound for easy removal of coating as coating delay the wound healing. Coatings are not allowing the prescribed medicine to reach at the affected site to kill the bacteria.

If the infection is extended in large areas of the body, then antibiotic treatment is essential for control the infection. Depending upon the severity, topical or oral antibiotic is prescribed. In severe cases, both formulations are required to administer. The effective treatment should accelerate healing of sores and normalize the skin texture without any skin mark development.

Usually the antibiotic therapy lasts for seven days. Completion of antibiotic course is important; otherwise it will create secondary infection. Early diagnosis and treatment control the further complication like cellulites, septicaemia, and psoriasis.

Some natural treatments are also effective in case of infentigo.

  • Application of the garlic paste at the affected site control the infection, as garlic has natural antibiotic property.
  • Aloe vera jell application maintain the moisture content of the affected area and prevents the dryness of the sore which helps to remove coat easily.
  • Addition of fruits and vegetables in the diet improve the immune system as they contain anti-oxidant property and fight against the infection.
