Causes include close contact, shared items, skin injuries, and poor hygiene. Prevention involves maintaining good hygiene and avoiding contact with infected individuals. Prompt medical treatment with topical or oral antibiotics is essential for effective recovery. Recognizing early signs and seeking professional advice can prevent complications, especially in vulnerable groups like the elderly or immunocompromised.

Understanding the Causes and Prevention of Impetigo in Children and Adults

Impetigo is a highly contagious skin infection caused by bacteria such as Staphylococcus and Streptococcus. It is most common among young children aged 2 to 5 but can also affect adults. Symptoms include red blisters filled with yellow fluid, which may ooze and form a crusty brown layer. Commonly affected areas include the face, hands, neck, and diaper region.

How children develop impetigo

  • Close contact with infected individuals
  • Sharing personal items like towels, toys, or clothing
  • Skin injuries like cuts or scrapes
  • Insect or animal bites

How adults can contract impetigo

  • Poor hygiene
  • Diabetes or weakened immune systems
  • Exposure in crowded environments like public transport and schools
  • Humid weather conditions increase risk

Preventive measures and treatment

If you suspect impetigo, consult a dermatologist or pediatrician promptly. In urgent cases, online images can assist in initial assessments, especially during travel. Self-medicating without professional advice is not recommended. A doctor may prescribe topical creams and oral antibiotics based on severity. Persistent or deep infections like ecthyma require medical attention as they penetrate deeper into the skin, typically affecting the legs, and are more common in elderly or immunocompromised individuals.
