What are the lesions of impetigo?
The main symptom of impetigo is reddish sores, often around the nose and mouth. The sores quickly rupture, ooze for a few days and then form a honey-colored crust. Sores can spread to other areas of the body through touch, clothing and towels. Itching and soreness are generally mild.
What are the two types of impetigo?
Impetigo is a highly contagious, superficial skin infection that most commonly affects children two to five years of age. The two types of impetigo are nonbullous impetigo (i.e., impetigo contagiosa) and bullous impetigo. The diagnosis usually is made clinically, but rarely a culture may be useful.
What skin lesions are characteristic for impetigo bullosa?
Bullous impetigo refers to lesions that have transparent, fragile, flaccid bullae or an outer rim of desquamation where bullae have ruptured.
Is impetigo itchy when healing?
The sores can be itchy and occasionally painful. After the crust phase, they form red marks that fade without leaving scars. Infants sometimes have a less common type of impetigo, with larger blisters around the diaper area or in skin folds.
What causes impetigo to flare up?
Causes of impetigo Impetigo occurs when the skin becomes infected with bacteria, usually either Staphylococcus aureus or Streptococcus pyogenes. The bacteria can infect the skin in two main ways: through a break in otherwise healthy skin – such as a cut, insect bite or other injury – this is known as primary impetigo.
What is the most probable diagnosis of impetigo?
To diagnose impetigo, your doctor might look for sores on your face or body. Lab tests generally aren’t needed. If the sores don’t clear, even with antibiotic treatment, your doctor might take a sample of the liquid produced by a sore and test it to see what types of antibiotics would work best on it.
