What is Impetigo?
Impetigo is a bacterial skin infection mostly affecting children aged two to five, but adults can catch it too. It's caused by bacteria invading the skin, either directly or through minor skin injuries like cuts or insect bites. The disease thrives in warm, humid environments and spreads easily in crowded places with poor hygiene.
Types of Impetigo
There are three main types of impetigo: nonbullous impetigo, bullous impetigo, and ecthyma. Nonbullous impetigo is the most common, starting as red sores that quickly burst and form a yellow-brown crust. Bullous impetigo is characterized by larger blisters filled with yellow fluid, while ecthyma is a deeper infection that causes painful ulcers.
Possible Complications
Though impetigo is usually mild, it can sometimes lead to complications. Poststreptococcal glomerulonephritis is a kidney condition that may occur after a streptococcal skin infection. Additionally, acute rheumatic fever has been linked to streptococcal skin infections in certain communities.
