Impetigo is a common skin condition characterized by the sudden appearance of red sores, typically around the nose, mouth, or on other areas of the face, arms, and legs. At PromiseCare in Hemet, California, medical professionals often see patients with these sores, which can ooze fluid and form a yellowish crust. Impetigo is highly contagious and can spread through skin contact, cuts, or scrapes, as well as by touching contaminated items.
If diagnosed with impetigo, symptoms can clear up with the right treatment and good hygiene habits. Treatment plans developed by healthcare providers at PromiseCare may include antibiotics and self-care measures to manage symptoms and prevent the spread of the condition. By understanding the causes, symptoms, and treatment options for impetigo, individuals can take the necessary steps to regain healthy skin.
Overview
Impetigo is a highly contagious bacterial skin infection that can spread quickly if left untreated. It often occurs when bacteria like Staphylococcus aureus and Streptococcus pyogenes enter the skin through a cut or scrape, or even through skin-to-skin contact with an infected person.
To prevent the spread of the infection, it’s essential to practice good skin hygiene. Keeping the skin clean, washing hands frequently, and avoiding touching the affected area can reduce the risk of transmission.
Symptoms
When dealing with a skin infection like impetigo, recognizing the symptoms is vital for prompt treatment and preventing further spread.
Red sores typically appear around the nose and mouth, which can break open, ooze fluid, and form a honey-colored crust. These sores are usually painless but can be itchy. Impetigo can spread to other areas through touch, clothing, and other items.
It’s essential to be aware of the symptom duration and take action quickly. Compared with other skin infections, impetigo symptoms can develop rapidly, often within a few days of infection.
If left untreated, the infection can last for several weeks, increasing the risk of complications. Recognizing the symptoms and seeking medical attention help prevent the infection from spreading and facilitate a speedy recovery.
Causes
Impetigo can be caused by pre-existing skin conditions and environmental factors.
Pre-existing skin conditions, such as eczema, increase the risk of contracting impetigo, as damaged skin is more vulnerable to infection. Additionally, open wounds can allow bacteria to penetrate the skin, ultimately leading to impetigo.
Exposure to close living quarters is another significant risk factor for contracting impetigo. Bacteria can easily spread through skin-to-skin contact, so living in close proximity to someone with impetigo poses a significant risk.
Risk factors
Impetigo risk factors include skin breaches such as minor cuts or bug bites, which provide an open invitation for impetigo-causing bacteria to invade.
Young children are at a higher risk, with impetigo occurring most commonly in kids ages 2 to 5. Warm, humid weather also increases impetigo infections.
Risk factors for impetigo infection include young age, as children under 5 are more susceptible due to their developing immune systems, broken skin through small cuts, insect bites, or rashes, poor hygiene practices such as infrequent hand washing, close contact with infected individuals allowing the bacteria to spread, and sharing personal items such as bedding or towels with someone who’s infected.
Complications
Complications of impetigo can be severe if left untreated or not managed properly. This highly contagious condition can spread quickly, increasing the risk of developing serious complications like cellulitis, a bacterial infection that can spread to the lymph nodes and bloodstream, potentially becoming life-threatening.
Long-term effects can also occur, including kidney problems like post-streptococcal glomerulonephritis, which can cause kidney damage. Seeking medical attention immediately upon noticing symptoms is crucial to preventing these complications.
Practicing good hygiene and following a treatment plan can also help prevent complications, reducing the risk of long-term effects and facilitating a full recovery.
Diagnosis
When your skin breaks out in itchy, pus-filled blisters, you want answers – and fast. Getting an accurate diagnosis is the first step towards healing and relief. A healthcare provider will examine the affected skin area, looking for signs like redness, swelling, and honey-colored crusts.
To confirm the diagnosis, they may perform laboratory tests like skin scrapings or swabs to identify the bacteria causing the infection.
Diagnostic criteria to evaluate include redness and swelling around the affected area, the presence of pus-filled blisters that rupture and form a honey-colored crust, the size and spread of the lesions, signs of systemic infection such as fever or swollen lymph nodes, and the results of laboratory tests including skin cultures and blood work.
Treatment
As the itchy, pus-filled blisters of impetigo spread across the skin, effective treatments are available to combat this highly contagious skin infection.
Topical treatments like mupirocin, retapamulin, and fusidic acid can be applied directly to the sores 2-3 times a day. Removing the crust with soap and water before application can help these antibiotics penetrate deeper.
For more severe cases or when the infection has spread, systemic antibiotics may be prescribed, including beta-lactamase-resistant antibiotics or other medications targeting MRSA.
With proper treatment, the duration of illness decreases, and the spread of lesions slows. Using topical or systemic treatments can help heal the infection and stop it from spreading.
Medications
Facing a diagnosis of impetigo can be overwhelming, but understanding the available medications can empower you to take control of your treatment.
Treatment options typically include topical treatments, which are applied directly to the skin, or systemic treatments, which are taken orally to combat the infection from within.
Common medications for impetigo include Mupirocin 2% cream or ointment, a topical antibiotic effective against localized, uncomplicated, non-bullous impetigo, Retapamulin 1% ointment, a topical antibiotic effective against S. aureus and S. pyogenes, Cephalexin, a systemic antibiotic commonly used for bullous impetigo and cases with more than five lesions, Clindamycin, a systemic antibiotic effective against MRSA, and Doxycycline, a systemic antibiotic suitable for treating MRSA, but not solely against Group A streptococcus.
Surgery
Impetigo treatments may involve surgery in severe cases or when complications develop. Surgical options may be necessary to manage the infection if it becomes severe or doesn’t respond to other treatments.
Pus or abscesses that form as a result of the infection may require surgical drainage to clear them. In severe cases of impetigo, debridement may be necessary to remove dead or infected tissue.
Impetigo can also sometimes lead to more severe conditions, such as cellulitis that progresses to necrotizing fasciitis, requiring prompt surgical intervention.
Surgery is usually considered a last resort and often isn’t required if antibiotic treatment begins early.
The severity of each case determines whether surgical options are necessary for effective infection management.
Lifestyle and home remedies
Impetigo can be frustrating and painful, but many lifestyle changes and home remedies can help manage the infection and prevent its spread.
Making a few simple changes to your daily routine can reduce the risk of getting impetigo again and speed up the healing process.
Wash sores with antibacterial or antiseptic soap every 8-12 hours, soaking off visible crust. Apply a waterproof occlusive dressing to prevent further spread. Change linen, including towels, sheets, face washers, and sleepwear, daily. Cutting fingernails short can prevent scratching and spread to other body areas. Using a clean washcloth and towel each time can also help prevent spreading the infection.
Preparing for your appointment
As you work to manage your impetigo symptoms and prevent its spread, you’ll eventually need to visit a healthcare provider to confirm the diagnosis and get personalized advice.
Before your appointment, take some time to prepare. Make a list of the symptoms you’re experiencing, including when the sores started and what they looked like initially. Write down all the medications, vitamins, and supplements you’re taking, as well as any other key medical information.
Come up with a list of questions, such as what might be causing the sores and what you can do to prevent the infection from spreading. Being prepared will help you get the most out of your appointment and ensure you receive the best possible care.
What you can do
To manage impetigo, focus on prevention strategies and infection control.
Wash affected areas daily with soap or cleanser to minimize transmission. Apply antibiotic ointment twice daily or as directed. Cover affected areas with a clean bandage when possible. Perform dilute bleach baths 2-3 times a week to reduce the bacterial count on the skin. Practice good hygiene, such as regularly inspecting skin for signs of infection and avoiding sharing personal items.
