Impetigo is an acute bacterial infection with lesions that contain a light,
yellow fluid. These vesicles erupt and form a golden crust. This disease is
more common in children and is contagious. Causes of impetigo include
streptococci and staphylococci bacteria. Poor hygiene, tropical climates, and
improper sanitation can contribute to infection. Oral antibiotics are generally
required along with topical treatment.
Parasitic Infections:
Scabies is one of the parasitic (needs a host) infections. It is caused by
the itch mite, sarcoptes scabiei, which burrows under the skin usually
beginning in the webs of the fingers and causes raised bumps. It eventually
spreads to the rest of the body but not usually the face. The itching is
intense and becomes worse a night. The infection is contagious and spread
through contact with an infected person. A dermatologist can diagnose the
infection and proscribe a mite killing lotion lindane (Kweel) or permethrin
(Elimite) that is applied to the entire body except for face after showing. It
is left on overnight and then washed off. A second application may be
necessary. All bedclothes and towels should be washed using hot water.
