Impetigo is a contagious bacterial skin infection characterized by red sores or blisters that can rupture, forming distinctive honey-colored crusts. While commonly affecting children, impetigo can also occur in adults and is often associated with areas of the skin with breaks, such as cuts or insect bites. At Pinnacle Dermatology, we understand the discomfort impetigo can cause and offer specialized care to alleviate symptoms and prevent the spread of infection.

There are three forms of impetigo:

Ordinary Impetigo: Caused by Streptococcal germs, ordinary impetigo appears as red sores that rupture quickly, ooze fluid, and then form honey-colored crusts. It primarily affects children from infancy to age two.

Bulbous Impetigo: Appearing as fluid-filled blisters, bulbous impetigo is caused by Staphylococcus germs. The infection is highly contagious and spreads through the fluid that oozes from the blisters.

Ecthyma: A more serious form of impetigo, ecthyma penetrates to the second layer of the skin (dermis). It is characterized by painful sores filled with fluid or pus, commonly appearing on the legs or feet. These lesions break open and scab with a hard yellow-gray crust and can also cause swollen lymph glands in the affected area.

Recognizing the importance of prompt treatment, our dermatology providers offer specialized care for impetigo, providing effective solutions to alleviate symptoms and prevent the spread of infection.

At Pinnacle Dermatology, your skin health is our priority. If you suspect impetigo, schedule an appointment with a trusted Pinnacle Dermatology provider for a thorough evaluation and a tailored treatment journey to healthy skin.

What are the Symptoms of Impetigo?

  • Single or multiple blisters filled with pus, which pop easily and leave a reddish, raw-looking base and/or honey-colored crust.
  • In most children, impetigo first appears near the nose and then spreads through scratching to other parts of the face, arms, or legs.
  • Itchy blisters.

Causes of Impetigo

  • Bacteria Staphylococcus aureus or Streptococcus pyogenes.
  • Bacteria entering the skin through cuts, scrapes, or existing skin conditions.
  • Bacteria exploiting the openings created by insect bites or the warm, moist environment around the nose and mouth.
  • Direct contact with the sores or by touching items like towels or clothing that have met the infected skin.
  • Warmth and humidity further promote the bacteria's growth, making certain environments more conducive to impetigo transmission.

How to Prevent Impetigo

Preventing impetigo involves adopting simple yet effective hygiene practices to reduce the risk of bacterial skin infection. Here are key preventive measures recommended by our dermatologists:
  • Regular Handwashing: Encourage frequent handwashing with soap and water, especially after activities that involve skin contact, playing in shared spaces, or using communal items.
  • Prompt Wound Care: Thoroughly clean and cover any cuts, scrapes, or insect bites to prevent bacteria from entering the skin. Immediate attention to minor injuries is crucial
  • Avoiding Skin-to-Skin Contact: Minimize direct skin contact with individuals showing signs of impetigo or other contagious skin conditions. Refrain from using personal items like towels or clothing belonging to an infected person.
  • Cleanliness in Shared Spaces: Maintain cleanliness in communal spaces, particularly in schools, daycares, and sports facilities. Regular disinfection of surfaces and shared items helps prevent the spread of bacteria.
  • Education: Teach individuals to use their own items for personal hygiene to reduce the risk of sharing bacteria. Educate individuals, particularly parents and caregivers, about the symptoms of impetigo and the importance of seeking medical attention promptly for diagnosis and treatment.
By incorporating these preventive measures into daily routines and promoting good hygiene practices, the risk of impetigo can be significantly reduced, fostering a healthier environment for individuals of all ages.

Impetigo FAQs

Yes, impetigo sores can be itchy. The red sores may break open, and the itching can be uncomfortable. Dermatologists can recommend treatments to soothe the itch and promote healing.

Impetigo is a contagious skin infection marked by red sores that turn into honey-colored crusts. It often appears around the nose and mouth. If you notice red sores that burst and form a golden crust, it might be impetigo.

With the right treatment, impetigo usually starts to improve within a few days. Dermatologists may recommend antibiotics to clear the infection. It's important to follow their advice for the prescribed duration.

How to Treat Impetigo

The primary course of action to treat impetigo involves a 7-10-day regimen of prescription oral antibiotics and/or topical antibiotics. These medications work to eliminate the bacteria causing the infection, aiding in the healing process. Individuals must complete the entire prescribed course of medications, even if the sores appear to be improving. This ensures complete eradication of the bacteria and minimizes the risk of recurrence.

Topical antibiotics available over the counter, such as Neosporin, are not recommended for treating impetigo. Our dermatologists prescribe specific formulations tailored to combat the specific bacteria responsible for the infection.
In addition to antibiotic therapy, our team may advise gentle cleansing of the affected areas to remove crusts and promote healing. It is important to refrain from picking at the sores to prevent further spread of the infection.
