Viral Skin Conditions

The varicella zoster virus (VZV) is the cause of chickenpox (varicella), and shingles (herpes zoster). Varicella occurs as the primary infection, more commonly in childhood but can occur in adulthood. Herpes zoster is a result of reactivation of latent infection of nerve ganglia. The rate of infection is currently trending downwards with the introduction of a varicella zoster virus vaccine.

 

Human Papilloma Virus (HPV) typically infects the cells of the skin and results in warts. Warts are an abnormal skin growth on the skin, taking on a variety of different appearances, and in any region of skin. These may occur at any location on the skin, and even on mucous membranes, such as genitalia. In some cases, pain, pruritus (itching), or local irritation may occur.

 

Herpes simplex virus (HSV) infection (called cold sores and genital herpes depending on the site of infection) is a common infection which results from contact with persons or hosts who have the infection. Whilst HSV infections generally have good prognosis, important complications may occur, particularly with immunocompromised patients or neonates.
