Several commonly contracted skin diseases include ringworm, impetigo, herpes gladiatorum, and staph infection. This includes impetigo, cellulitis, pneumonia, septic arthritis, and otitis externa. Sometimes these clinical manifestations are not ringworm but appear as impetigo, scleroderma or psoriasis. Some disease processes caused by pyogenic infections are impetigo, osteomyelitis, septic arthritis and necrotizing fasciitis. The most common of these infections include streptococcal pharyngitis (strep throat) and impetigo. Examples of soft-tissue infections from MRSA include ulcers, impetigo, abscesses, and SSIs. "S. pyogenes" causes diseases ranging from pharyngitis to life-threatening impetigo including necrotizing fasciitis. This includes fungal infections of the foot, impetigo, pemphigus, superficial wounds, dermatitis, and tropical ulcers. Occasionally, secondary infection with bacteria occurs with concurrent pustules and impetigo. Some of these evacuees included children diagnosed with scabies and impetigo. Pemphigus vulgaris is easily confused with impetigo and candidiasis. The most common are chickenpox, herpes, impetigo, and a form of eczema called dyshidrosis. Impetigo is a highly contagious skin infection. Impetigo is a bacterial infection that involves the superficial skin. If impetigo is left untreated other infections could occur which can cause serious health issues.
