Types of Impetigo

Overview

Impetigo is a highly contagious skin infection that can affect people of all ages, but it is most commonly seen in children. There are two main types of impetigo: non-bullous impetigo and bullous impetigo. Here are descriptions of each type and the characteristics that are common and unique across both types:

Non-bullous impetigo:

• This is the most common type of impetigo.
• It starts with clusters of red or discolored itchy sores, typically around the mouth and nose.
• These sores can burst and develop into thick, honey-colored crusts.
• The infection can spread to other areas of the body.
• In some cases, nearby glands may become swollen.
• Without treatment, non-bullous impetigo usually resolves within a few weeks without scarring.

Bullous impetigo:

• Bullous impetigo is less common than non-bullous impetigo.
• It begins with fluid-filled blisters that usually appear on the trunk (between the neck and waist).
• These blisters enlarge quickly, burst, and become covered with a honey-colored crust.
• Unlike non-bullous impetigo, there is usually no redness or swelling associated with bullous impetigo.
• The blisters in bullous impetigo stay longer without bursting compared to non-bullous impetigo.

Common characteristics across both types of impetigo:

• Impetigo is highly contagious and can spread through close contact with an infected person or their personal items.
• The infection is usually caused by bacteria such as Staphylococcus aureus or Streptococcus pyogenes.
• Symptoms may include blisters or sores that burst and ooze before drying up, leading to the formation of crusts.
• Impetigo can be itchy and uncomfortable.
• Treatment typically involves applying an antibiotic ointment or cream to the affected area.

It's important to seek medical treatment if you suspect you have impetigo. Your healthcare provider can provide an accurate diagnosis and recommend appropriate treatment options based on your specific situation.
