What is impetigo?

Impetigo is a highly infectious skin infection primarily caused by bacteria, specifically Staphylococcus aureus or Streptococcus pyogenes. The condition is characterized by the appearance of red sores, blisters, or crusty patches on the skin, often around the nose and mouth, but it can occur anywhere on the body. This infection is particularly common among young children, as they are more susceptible due to their close interactions and less developed immune systems.

The contagion aspect of impetigo is significant; it can spread rapidly through direct contact with the sores or through contact with items that have been contaminated, such as towels or clothing. Understanding that impetigo is easily transmitted helps in emphasizing the importance of proper hygiene and the need to avoid sharing personal items to prevent outbreaks.

Other options do not accurately represent impetigo. While some skin conditions may be contagious or caused by allergens or fungi, each has distinct characteristics and causes that differ from those of impetigo.
