What Causes Infectious Rashes

Skin Rash, Causes, Signs and Symptoms, Diagnosis and Treatment.

Skin rashes have an exhaustive list of potential causes, including infections. In a broad sense, rashes are commonly categorized as infectious or noninfectious.

Causes of infectious rashes include:


  • Trichophyton is a type of skin fungus that commonly causes rashes of the skin, hair, and nails. This infectious rash is called tinea or ringworm. It may occur on any body surface.
  • Candida can cause common yeast infections in moist areas like between the fingers, in the mouth, vaginal area, and also in the groin folds. It would be unusual to have a Candida rash in a dry body area.
  • Other much less common fungal infections include cryptococcosis, aspergillosis, and histoplasmosis. These are fairly uncommon in healthy people and are more frequently seen in individuals with a compromised immune system as in HIV/AIDS, immune suppression due to cancerchemotherapy, and patients on long-term immunosuppression because of organ transplant or hematologic diseases.


  • Herpes simplex types I and II may cause infections of the lips, nose, facial skin, genitals, and buttocks. HSV infections may also cause erythema multiforme , which is characterized by tender bull’s eye-like targets on the palms, usually corresponding to an HSV flare.


Scabies is a very itchy, contagious superficial skin infestation with a microscopic mite.Lice infestations may cause different types of itchy rashes in the affected areas like the scalp and nape of the neck or pubic area.

Some treatments, such as oatmeal baths, may help control the itching of both infectious and noninfectious rashes.

    Infectious Rashes

    • Fungal
    • Tinea or ringworm infections of the skin, hair, and nails are treated by topical and/or oral antifungal medications like terbinafine.
    • Candida infections are treated with topical antifungal medications like clotrimazole and sometimes with oral antifungal drugs like fluconazole . Nystatin will not treat ringworm, nor will griseofulvin treat yeast.
    • Atypical fungal infections, including cryptococcosis, aspergillosis, and histoplasmosis, are generally treated with an oral or intravenous course of special antifungal medications.
  • Viral
  • Herpes infections are usually treated with oral or intravenous antiviral medications, including acyclovir , famciclovir , valacyclovir , ganciclovir , and cidofovir . Depending on the severity of the individual infection and factors relating to the patient’s immune system, specific antiviral treatment may not be required or more aggressive treatment may be recommended.
  • Vaccination is an effective prevention measure to help ward off infections with the herpes zoster virus, which causes chickenpox and shingles.
