märkärupi

Märkärupi, commonly known as impetigo, is a common bacterial skin infection that primarily affects infants and children. It is highly contagious and typically presents as red sores that quickly rupture, ooze, and then form a yellowish-brown crust. These sores are often found on the face, especially around the nose and mouth, but can also appear on hands and feet.

There are two main types of impetigo. The more common form, non-bullous impetigo, starts as small red spots that blister and then rupture, leaving a characteristic honey-colored crust. Bullous impetigo is less common and characterized by larger, fluid-filled blisters that may appear anywhere on the body. These blisters can be painful and may rupture, leaving a moist, red area.

The infection is caused by Staphylococcus aureus or Streptococcus pyogenes bacteria. Transmission occurs through direct contact with the sores or with contaminated items such as towels, clothing, or toys. Outbreaks can spread rapidly in group settings like schools and daycares. Poor hygiene can contribute to the spread.

Diagnosis is usually made based on the characteristic appearance of the sores. A healthcare professional may sometimes take a swab of the infected area to confirm the bacterial cause. Treatment typically involves topical antibiotic ointments or oral antibiotics, depending on the severity of the infection. Keeping the affected areas clean and taking precautions to prevent spreading the infection to others are important aspects of management.
