Impetigo: Common, Contagious Skin Infection Affecting All Ages
Impetigo, a common and highly contagious bacterial skin infection, is affecting people of all ages, with children being particularly susceptible. Characterized by red sores and blisters, often with a yellowish crust, it typically appears on the face, especially around the nose and mouth. Two types of bacteria, Staphylococcus aureus or Streptococcus pyogenes, usually cause this condition, which can enter the skin through minor cuts or insect bites.
Impetigo is diagnosed through a physical examination, medical history, and laboratory tests like bacterial culture and Gram stain. Treatment involves topical antibiotic creams or ointments for mild cases, and oral antibiotics for more severe infections. Good hygiene practices, such as regular hand washing and keeping the affected area clean, are also crucial. Home remedies like warm compresses, oatmeal baths, tea tree oil, and aloe vera gel can soothe the skin and promote healing, but they should not replace medical treatment.
Certain individuals are more prone to developing impetigo. These include children under the age of 6, people with weakened immune systems, those with skin conditions like eczema or dermatitis, and individuals who participate in sports involving constant contact. The infection can spread through direct contact with an infected person or contaminated surfaces.
If left untreated or if the infection spreads, impetigo can lead to complications such as cellulitis, post-streptococcal glomerulonephritis, ecthyma, scarring, and skin cancer. Therefore, prompt medical attention is essential. With proper treatment and hygiene, impetigo is usually curable within two to three weeks.
