What are the symptoms of impetigo?
Impetigo is a mild infection and can affect any part of the body. Mostly, it affects the nose and mouth or arms or legs.
- Red, itchy sores
- Leaks pus for a few days
- A yellow-colored scab formed over the sores
There are three types of impetigo
- Nonbullous impetigo: This is the most common form of impetigo caused by Staphylococcus and Streptococcus bacteria. It begins as small red papules that are similar to those of insect bites. These papules enlarge to small blisters and then to pustules that tend to break and form a golden crust. It takes about one week to develop. Sores are painless but itchy.
- Bullous impetigo: This type of impetigo is primarily seen in children and is caused due to S. aureus bacteria. It mainly affects the trunk and is characterized by the formation of blisters (bullae) with a clear yellow liquid, which later turns darker and turbid. Symptoms of fever and swollen glands may be observed with this type of impetigo.
- Ecthyma: This is characterized by a yellow, punched-out rash that extends deep through the skin. The rash is similar to impetigo and is a severe form of impetigo.
