Author By: Jolene Sim, Health Team Contributor on 10 Jun, 2018

Impetigo is a skin condition that is very common and contagious. While this condition is usually more likely to affect children, it can also occur in adults at any age. In some regions, impetigo is also known as “school sores”. In the year 2010, impetigo affected as 2% of the global population (approximately 140 million individuals). It only involves the superficial layer of the skin. Some of the risk factors of impetigo include being in a day care center, inadequate nutrition, crowding, contact sports, diabetes, and open wounds in the skin due to mosquito bites, scabies, herpes, or eczema. Spread can occur if there is contact with the affected individual.

To prevent it from spreading, hand washing and cleaning the affected area can be useful. The condition can resolve on its own within three weeks without treatment. However, some complications such as cellulitis and poststreptococcal glomerulonephritis can occur.

Impetigo Cause #1: Staphylococcus Aureus

Staphylococcus aureus is a bacterium that can be found on the human body. It is commonly found in the nose, skin, and respiratory tract. While it is not always pathogenic (it is not always harmful), it can cause many different conditions such as abscess, food poisoning, folliculitis, and impetigo.

Skin infection such as folliculitis and impetigo occur when there is a wound in your skin due to a cut, scratch, or insect bite. The bacterium invades the wound and start colonizing the area causing an infection. The bacterium will then start to produce toxins which causes the upper layers of the skin to break apart, causing blisters and other symptoms.
