Impetigo is a highly contagious bacterial skin infection, commonly affecting infants and young children. It's characterized by sores and blisters, often with a yellowish crust.
Understanding Impetigo
Impetigo is an infection of the skin's outer layer (epidermis). It's predominantly caused by gram-positive bacteria, most frequently Staphylococcus aureus (staph) or Streptococcus pyogenes (group A strep). The infection is highly contagious and spreads easily through direct contact with infected individuals or contaminated surfaces.
Symptoms
Common symptoms of impetigo include:
- Itchy, red skin
- Blisters that burst, weeping a yellowish fluid
- Crust formation over sores
- Most commonly found around the nose and mouth, but can occur on other areas of the body.
The infection is typically not severe, but prompt treatment is essential to prevent spreading and complications.
Causes
As mentioned above, impetigo is primarily caused by Staphylococcus aureus or Streptococcus pyogenes. These bacteria can enter the skin through minor cuts, abrasions, or insect bites. The bacteria then multiply, leading to the characteristic sores and blisters. Another name for impetigo is sometimes infantigo.
Contagiousness
Impetigo is highly contagious. The bacteria can easily spread through direct contact with an infected person or indirectly through shared items like towels, clothing, or bedding. Good hygiene practices are crucial in preventing transmission.
Treatment
Treatment options usually involve topical or oral antibiotics prescribed by a doctor. The severity and location of the infection will determine the best course of treatment.
