Introduction
Impetigo is a common skin infection that mainly affects children, but can also occur in adults. It is highly contagious and can spread rapidly in schools, daycares, and other close-quarters settings. In this article, we will explore what impetigo is, its causes, symptoms, treatment options, and prevention measures.
Causes of Impetigo
Impetigo is caused by two types of bacteria: Staphylococcus aureus and Streptococcus pyogenes. These bacteria can enter the skin through cuts, scrapes, insect bites, or other breaks in the skin’s barrier. Poor hygiene, crowded living conditions, and warm weather can increase the risk of developing impetigo.
Symptoms of Impetigo
- Red sores or blisters on the face, arms, or legs
- Sores that burst and develop a honey-colored crust
- Itching and discomfort
Treatment Options
Impetigo is usually treated with antibiotics, either in the form of topical creams or oral medications. It is important to finish the full course of antibiotics to prevent the infection from recurring. Keeping the skin clean and dry can also help speed up the healing process.
Prevention Measures
- Practice good hygiene, including regular handwashing
- Keep cuts and scrapes clean and covered
- Avoid sharing personal items, such as towels
Case Studies
Emily, a 7-year-old girl, developed impetigo after playing in the school yard without washing her hands. Her parents took her to the doctor, who prescribed antibiotics and recommended keeping the affected area covered until it healed.
Statistics
According to the Centers for Disease Control and Prevention, impetigo is more common in children aged 2-5 years, with an estimated 2% of children affected each year.
