Impetigo
Overview of Impetigo
Impetigo is a highly contagious bacterial skin infection that commonly affects infants and young children but can also occur in adults. It often starts as red sores or blisters, which quickly rupture and develop a yellowish-brown crust. If you are wondering what is impetigo or infantigo, they are actually the same condition that is caused by bacteria like Staphylococcus aureus or Streptococcus pyogenes. This condition is more prevalent in warm and humid climates and among individuals with compromised skin integrity.
Types of Impetigo
- Non-bullous impetigo (Impetigo contagiosa): The most common form, presenting as small blisters or sores, particularly around the nose and mouth.
- Bullous impetigo: Characterised by larger, fluid-filled blisters often seen in newborns and young children.
- Ecthyma: A more severe form that penetrates deeper into the skin, potentially causing ulcers and scarring.
Symptoms of Impetigo
- Red sores or impetigo rash around the nose, mouth, hands or legs.
- Blisters that ooze and form honey-colored crusts.
- Itching or discomfort in the affected area.
- Swollen lymph nodes near the infection site.
- Infantigo symptoms often include fussiness, fever and skin irritation in babies.
- Mild impetigo rash can go unnoticed initially but may spread rapidly.
Causes of Impetigo
- Caused primarily by impetigo bacteria like Staphylococcus aureus or Streptococcus pyogenes.
- Breaks in the skin from cuts, scrapes, eczema or insect bites.
- Poor hygiene or crowded living conditions.
- Direct contact with infected individuals or contaminated items such as towels, toys.
Complications in Impetigo
- Cellulitis (a deeper skin infection)
- Scarring or skin discoloration
- Post-streptococcal glomerulonephritis (a rare kidney complication)
- Spread to other body parts or people, especially in daycare or school settings
Risk Factors of Impetigo
- Age is the main factor — common in children (especially 2–5 years)
- Hot and humid environments
- Skin injuries or chronic conditions like eczema
- Close contact in schools, daycare or sports teams
- Weakened immune system
Preventions of Impetigo
- Maintain good personal hygiene
- Regular handwashing with soap and water
- Avoid sharing personal items like towels or razors
- Keep wounds clean and covered
- Avoid contact with individuals who have active impetigo
- Prompt treatment of any skin injury
Diagnosis of Impetigo
- Clinical examination based on appearance of the impetigo rash or blisters.
- In rare cases, swab testing to identify the impetigo bacteria.
- Differential diagnosis to rule out other skin conditions like eczema or herpes.
Treatments of Impetigo
- Topical antibiotics like mupirocin or fusidic acid for mild cases.
- Oral antibiotics for widespread or stubborn infections.
- Gentle cleansing of the infected area with soap and water.
- Avoid scratching or touching the lesions to prevent spread.
- Patients must complete the full course of treatment even if symptoms subside early.
Prognosis of Impetigo
- Most cases of impetigo heal completely within 7 to 10 days with proper treatment.
- Early diagnosis and care help avoid complications and prevent the infection from spreading.
- Children and adults respond very well to treatment, especially when it’s started promptly.
- Once healed, the skin usually returns to normal with little to no scarring.
- With good hygiene and preventive steps, future outbreaks can often be avoided.
- For patients with recurring impetigo, long-term skin care plans can help reduce flare-ups.
- Even in more severe cases like bullous impetigo, full recovery is possible with expert medical support.
