Impetigo is a common and highly contagious bacterial skin infection that primarily affects young children, though it can occur in individuals of any age. This article provides a comprehensive overview of impetigo, including its definition, types, causes, and risk factors. Furthermore, it delves into the symptoms and diagnostic approaches for identifying this condition, along with the various treatment options available.

Additionally, we will discuss the preventive strategies to reduce the risk of impetigo transmission and potential complications and prognosis. Understanding impetigo and how to manage it effectively is crucial in promoting skin health and preventing its spread within communities.

1. An Overview

Definition

Impetigo is a highly contagious bacterial skin infection that primarily affects infants and young children, though it can occur in adults. It manifests as red sores, usually around the nose and mouth, that quickly rupture, ooze for a few days, and then form a yellow-brown crust.

Types of Impetigo

Non-Bullous Impetigo (Impetigo Contagiosa)

• Description: This is the most common form of impetigo. It starts with red sores around the mouth and nose or other areas of the face. These sores burst and develop honey-colored crusts.
• Bacteria Involved: Typically caused by Staphylococcus aureus or Streptococcus pyogenes.

Bullous Impetigo

• Description: This type involves larger blisters filled with a clear fluid that becomes darker and cloudy. These blisters are less likely to rupture and form a crust compared to non-bullous impetigo.
• Bacteria Involved: Exclusively caused by Staphylococcus aureus.

Ecthyma

• Description: This is a more severe form of impetigo where the infection penetrates deeper into the skin, forming painful fluid- or pus-filled sores. These sores can turn into ulcers and leave scars.
• Bacteria Involved: Often caused by Streptococcus pyogenes, sometimes in combination with Staphylococcus aureus.

2. Causes and Risk Factors

• Age: Children aged 2 to 5 years are most commonly affected.
• Close Contact: Participation in activities involving close physical contact, such as sports or daycare, increases the risk.
• Warm, Humid Weather: Impetigo is more common in warm and humid climates.
• Skin Injury: Minor skin injuries, insect bites, and other skin conditions like eczema can increase susceptibility.
• Weakened Immune System: Individuals with weakened immune systems are at higher risk.
• Poor Hygiene: Poor hygiene practices can facilitate the spread of the infection.

Prevention

• Hygiene: Regular handwashing and good personal hygiene are crucial.
• Wound Care: Proper care of cuts, scrapes, and insect bites to prevent infection.
• Avoid Sharing Personal Items: Do not share towels, clothing, or personal care items.
• Isolation of Infected Individuals: Keeping infected individuals away from others until they are no longer contagious helps prevent the spread.

Treatment typically involves topical or oral antibiotics, depending on the severity of the infection.

3. Symptoms and Diagnosis

Impetigo is a common and highly contagious bacterial skin infection that mainly affects infants and young children. Here are the key symptoms and how to diagnose them.

Symptoms of Impetigo

1. Red Sores: The most characteristic sign is the appearance of red sores, usually on the face, especially around the nose and mouth, as well as on the hands and feet.
2. Oozing and Crusting: These sores quickly burst, ooze for a few days, and then form a yellowish-brown crust.
3. Itching and Soreness: The affected area can be itchy and tender.
4. Blisters: In some cases, impetigo may cause fluid-filled blisters (bullous impetigo) that can enlarge and burst.
5. Swollen Lymph Nodes: Sometimes, nearby lymph nodes may become swollen.

Diagnosis of Impetigo

1. Physical Examination: A healthcare provider can often diagnose impetigo by examining the characteristic sores.
2. Culture Test: Sometimes, a swab of the infected area may be taken to identify the bacteria (typically Staphylococcus aureus or Streptococcus pyogenes) and to determine antibiotic sensitivity.
3. Differential Diagnosis: The doctor may differentiate impetigo from other skin conditions like eczema, herpes, or contact dermatitis.

When to Seek Medical Advice

• If sores are not healing or are spreading
• If the child is experiencing pain or fever
• If there are signs of more severe infection, such as redness and swelling spreading from the sores

Early treatment with antibiotics, either topical or oral, is essential to prevent the spread of the infection and to hasten recovery.

4. Treatment Options

Topical Antibiotics

Topical antibiotics like mupirocin can be applied directly to the sores to help clear the infection.

Oral Antibiotics

In severe cases, oral antibiotics such as dicloxacillin or cephalexin may be prescribed to combat the bacteria internally.

Home Care

Keeping the affected area clean, avoiding scratching, and regularly changing dressings can help promote healing and prevent spreading the infection to others.
