Understanding Impetigo: Causes, Symptoms and Risk Factors

Get Impetigo Treatment in Brixton

Impetigo is a common and highly contagious skin infection that primarily affects children but can occur in people of any age. It’s characterised by red sores or blisters that burst and develop a honey-coloured crust. While it’s usually not serious, understanding its causes, symptoms, and risk factors is crucial for effective management and prevention.

Causes of Impetigo

Impetigo is primarily caused by two types of bacteria: Staphylococcus aureus and Streptococcus pyogenes. These bacteria commonly reside on the skin and can enter the body through cuts, scratches, or insect bites. Once inside, they multiply and cause infection.

Symptoms of Impetigo

The hallmark symptom of impetigo is the appearance of red sores or blisters, usually around the mouth and nose but can occur anywhere on the body. These sores may burst and ooze fluid, eventually forming a yellow-brown crust. Other symptoms may include itching, swollen lymph nodes, and fever in severe cases.

Risk Factors for Impetigo

Several factors increase the risk of developing impetigo:

Age: Children aged 2 to 5 years are most susceptible due to their immature immune systems and frequent skin-to-skin contact in schools and daycare settings.

Warm Weather: Impetigo is more common in warm and humid climates where bacteria thrive.

Poor Hygiene: Lack of proper hygiene, such as infrequent handwashing, can facilitate the spread of bacteria.

Skin Conditions: People with existing skin conditions like eczema or dermatitis are more vulnerable as their skin barrier may be compromised.

Close Contact: Living in crowded environments or having close contact with an infected individual increases the risk of transmission.

Transmission of Impetigo

Impetigo is highly contagious and spreads through direct contact with an infected person or contaminated objects such as towels, bedding, or clothing. Scratching the sores can also spread the infection to other parts of the body or to other people.

How to Get Rid of Impetigo in 24 Hours

While impetigo typically requires medical treatment, it’s important to note that complete resolution within 24 hours may not be feasible. Prompt intervention can help accelerate healing and reduce the risk of spreading the infection. Here are some steps recommended by pharmacists at Junction Pharmacy in Brixton:

Antibacterial Creams: Over-the-counter antibacterial creams containing ingredients like mupirocin or fusidic acid can help eliminate the bacteria causing impetigo. Apply the cream directly to the affected areas as directed.

Keep the Area Clean: Gently wash the affected areas with warm water and a mild soap to remove crusts and prevent further bacterial growth. Pat the skin dry with a clean towel.

Topical Antiseptics: Applying antiseptic solutions like hydrogen peroxide or diluted bleach may help disinfect the skin and promote healing. However, these should be used cautiously and only as directed by a healthcare professional.

Oral Antibiotics: In severe cases or when the infection spreads, oral antibiotics prescribed by a doctor may be necessary to eradicate the bacteria from the body.

It’s essential to follow the prescribed treatment regimen and complete the full course of antibiotics even if symptoms improve. Additionally, practice good hygiene, such as regular handwashing and avoiding close contact with infected individuals, to prevent reinfection and transmission.
