märkähaavaa

Märkähaava, also known as impetigo, is a common bacterial skin infection. It primarily affects infants and children but can also occur in adults. The infection is caused by Staphylococcus aureus or Streptococcus pyogenes bacteria. Märkähaava is highly contagious and spreads through direct contact with the sores or contaminated items like towels or clothing.

There are two main forms of märkähaava. The non-bullous form, which is more common, begins as small red spots that quickly turn into blisters. These blisters then rupture, leaving behind moist, weeping sores that eventually form a yellowish-brown crust, often described as honey-colored. The bullous form is characterized by larger blisters that may not rupture.

Märkähaava typically appears on the face, especially around the nose and mouth, and on the hands and feet. It is usually not serious and clears up with appropriate treatment. However, in rare cases, it can lead to complications such as cellulitis, lymph node swelling, or kidney inflammation.

Diagnosis is usually made based on the characteristic appearance of the sores. Treatment typically involves topical or oral antibiotics prescribed by a healthcare professional. Good hygiene practices, such as washing hands frequently and keeping the affected areas clean, are important to prevent the spread of the infection. Avoiding scratching the sores also helps prevent further spreading and complications.
