Clinical features: Bacterial skin infections can be either impetigo, erysipelas or recurrent boils. All these are caused by either staphylococcus alone or together with streptococcus but rarely streptococcus alone. There are other non-bacterial skin infections e.g. viral (warts, herpes simplex, herpes zoster and varicella, kaposis varicelliform eruption), fungal (candidiasis, ringworm and tinea vesicolor), skin infestations (scabies and pediculosis).
