Impetigo is a contagious skin infection caused by bacteria, commonly Staphylococcus aureus or Streptococcus pyogenes. It tends to affect children more frequently but can occur in people of all ages. The infection typically enters the skin through minor breaks in the skin’s integrity, such as cuts or insect bites.
The most common symptoms of impetigo are red sores or blisters, which often appear on the face, particularly around the nose and mouth, and occasionally on other body parts. These sores quickly rupture and form yellow-brown crusts. Impetigo can be itchy, and the infection can easily spread through direct skin-to-skin contact, as well as through touching contaminated objects like towels, bed linens, or clothing. As a result, it is often found in close-contact environments such as schools and daycare centers.
Impetigo comes in two primary types: non-bullous and bullous. Non-bullous impetigo is the more common form, characterized by sores that rupture and develop honey-colored crusts. On the other hand, bullous impetigo is less common but more severe, resulting in the development of large, fluid-filled blisters.
Treatment for impetigo typically involves the use of topical antibiotics, such as antibiotic ointments or creams, to help clear the infection. In more severe or widespread cases, oral antibiotics may be prescribed. It’s essential to complete the entire course of antibiotics as prescribed to ensure the infection is entirely eradicated.
Preventing impetigo involves maintaining good hygiene practices. Regular handwashing, keeping open sores covered, and avoiding close contact with infected individuals can help minimize the spread of the infection. Additionally, washing clothing, towels, and bedding that may have come into contact with an infected person is crucial to prevent the bacteria from persisting on these items.

Do you want to know more about impetigo? Let’s take a look at these 13 interesting facts about impetigo.
- Highly Contagious: Impetigo is one of the most contagious skin infections, particularly among children. It spreads easily through direct skin contact and by touching contaminated objects.
- Common in Children: While impetigo can affect people of all ages, it is most common in children aged 2 to 6 years.
- Bacterial Causes: It is primarily caused by two types of bacteria, Staphylococcus aureus and Streptococcus pyogenes, which can enter the skin through cuts, insect bites, or other minor injuries.
- Visible Symptoms: The characteristic sores and blisters of impetigo are often accompanied by a golden or honey-colored crust that forms after the sores rupture.
- Types of Impetigo: There are two main types of impetigo, non-bullous and bullous. Non-bullous impetigo is the most common, while bullous impetigo is less frequent but more severe.
- Itchy Skin: The infection can cause itching, discomfort, and occasionally mild pain for those affected.
- Common Sites: Impetigo typically occurs on the face, especially around the nose and mouth, but can also appear on other areas of the body.
- Prevalence in Warm Weather: Impetigo is more common in warm and humid climates and is often associated with the summer months.
- Resolves Quickly: With appropriate treatment, impetigo tends to resolve relatively quickly, typically within a week or two.
- Oral and Topical Antibiotics: Treatment often involves the use of oral or topical antibiotics to eliminate the infection. Completing the full course of antibiotics is essential.
- Complications: If left untreated, impetigo can lead to complications such as cellulitis, a deeper skin infection, or post-streptococcal glomerulonephritis, a kidney condition.
- Hygiene Practices: Good hygiene practices, including frequent handwashing and keeping open sores covered, can help prevent the spread of impetigo.
- Infection Recurrence: While impetigo is typically a one-time infection, some individuals may experience recurrent episodes, particularly if living in close-contact environments.
Impetigo is a highly contagious yet treatable skin infection that predominantly affects children but can impact individuals of all ages. Recognizable by its characteristic sores and golden crusts, this common skin ailment responds well to antibiotics and good hygiene practices. The swift resolution of symptoms, typically within a week or two with appropriate treatment, underscores the importance of early intervention. As a reminder, practicing good hygiene, keeping open sores covered, and avoiding close contact with infected individuals are vital steps in preventing the spread of impetigo. Seeking timely medical attention when symptoms arise ensures a swift and effective recovery, allowing individuals to return to their daily routines free of this skin condition.
