Impetigo is a highly contagious bacterial skin infection that primarily affects children, although it can occur in individuals of any age. It is characterized by the development of red sores or blisters that rupture, forming honey-colored crusts. Understanding the causes, symptoms, and treatment options for impetigo is essential for prompt and effective management.

Causes of Impetigo:

Bacterial Infection:

Impetigo is primarily caused by bacterial infection, often involving Staphylococcus aureus or Streptococcus pyogenes (Group A Streptococcus).

Skin Injury or Irritation:

Breaks in the skin, such as cuts, abrasions, or insect bites, provide an entry point for bacteria, increasing the risk of impetigo.

Close Contact:

Impetigo is highly contagious and can spread through close contact with an infected person or by touching contaminated surfaces.

Poor Hygiene:

Lack of proper hygiene, including infrequent handwashing, can contribute to the spread of impetigo.

Warm and Humid Conditions:

Impetigo is more common in warm and humid environments where bacteria thrive.

Symptoms of Impetigo:

Sores or Blisters:

Small red sores or blisters appear on the skin, often around the face, hands, or diaper area.

Honey-Colored Crusts:

The sores rupture and develop a characteristic honey-colored crust or scab, giving the skin a “coated” appearance.


Itching is common, and scratching can further spread the infection. It is advised to visit a Best Dermatologist in Islamabad to get the necessary treatment for impetigo.

Enlarged Lymph Nodes:

Swollen and tender lymph nodes may be present in the affected area.

Fever (in some cases):

Some individuals, particularly children, may experience a mild fever.

Treatment of Impetigo:

Topical Antibiotics:

Mild cases can often be treated with topical antibiotics, such as mupirocin, applied directly to the affected area.

Oral Antibiotics:

In more severe cases or when multiple areas are affected, oral antibiotics (such as cephalexin or amoxicillin) may be prescribed.

Good Hygiene Practices:

Encourage frequent handwashing and ensure proper hygiene to prevent the spread of infection.

Avoid Scratching:

Discourage scratching to prevent the spread of bacteria and worsening of the sores.

Keep Sores Clean:

Gently clean the affected areas with mild soap and water and apply an antibiotic ointment as directed by a healthcare professional.

Cover Sores:

Keep the impetigo sores covered with gauze or a clean cloth to reduce the risk of spreading the infection.


Individuals with impetigo should avoid close contact with others until the sores are healed and no longer contagious.

Prompt Medical Attention:

Seek medical attention if there is no improvement with home care, if the infection worsens, or if there are signs of complications.

It’s important to complete the full course of antibiotics as prescribed by a healthcare professional to ensure the infection is fully eradicated. Additionally, practicing good hygiene and promoting a clean environment can help prevent the recurrence and spread of impetigo. If there are concerns about impetigo, consult with a Dermatologist for an accurate diagnosis and appropriate treatment.
