What are the symptoms of impetigo?
It first appears as a small scratch or itchy patch of eczema - skin inflammation - on seemingly healthy skin. A small red, itchy spot quickly develops into a blister containing a yellow substance. Later, the top of the blister becomes crusty and weeps while new blisters develop in the same place or on other parts of the body. Impetigo usually begins on the face, especially
around the corners of the mouth, the nose and back of the ears.
Impetigo causes small bumps or blisters that burst. The skin underneath is moist, tender and red, and it oozes a clear liquid. A honey-colored crust, which may itch, then forms over the reddened area. If the disease is more severe cases, you also may have a fever and swelling of the lymph glands (swollen glands) in the face or neck.
Impetigo has two general forms: ordinary impetigo and bullous impetigo. Ordinary impetigo is scabby and pustular (little pimples full of pus) in appearance and is generally caused by strep germs. It starts as a small blister or pustule that ruptures and leaves a reddish base which is then covered by a honey-colored crust. In children, this condition often begins on the skin near the nose, though it may spread. Ordinary impetigo is also known as impetigo vulgaris and streptococcal impetigo. Bullous impetigo produces large, fragile blisters and is caused mostly by staph germs. It also often affects the face, but may appear elsewhere. The blisters it forms have very thin walls that collapse, leaving a bright red, inflamed, moist base. Bullous impetigo is also known as impetigo bullosa and staphylococcal impetigo.
