Herpes gladiatorum is a skin infection primarily caused by the herpes simplex virus. The virus infects the cells in the epidermal layer of the skin. The initial viral replication occurs at the entry site in the skin or mucous membrane. [7] The infections caused by a HSV Type 1 virus may be primary or recurrent. [8]
Once the chickenpox has resolved, the virus can remain dormant (inactive) in human nerve cells (dorsal root ganglia or cranial nerves) [11] for years or decades, after which it may reactivate and travel along nerve bodies to nerve endings in the skin, producing blisters. [1] [8] During an outbreak of shingles, exposure to the varicella virus ...
Genital herpes is classified as a sexually transmitted infection. [1] It may be spread to an infant during childbirth. [1] After infection, the viruses are transported along sensory nerves to the nerve cell bodies, where they reside lifelong. [2] Causes of recurrence may include decreased immune function, stress, and sunlight exposure. [2] [3 ...
Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level. It is a specialized field of study in virology. [1] Pathogenesis is a qualitative description of the process by which an initial infection causes disease. [2]
Herpes simplex virus 1 (cold sores) and 2 (genital herpes) (HSV-1 and HSV-2), also known by their taxonomic names Human alphaherpesvirus 1 and Human alphaherpesvirus 2, are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans. [1] [2] Both HSV-1 and HSV-2 are very common and ...
Molluscum contagiosum (MC), sometimes called water warts, is a viral infection of the skin that results in small raised pink lesions with a dimple in the center. [1] They may become itchy or sore, and occur singularly or in groups. [1] Any area of the skin may be affected, with abdomen, legs, arms, neck, genital area, and face being the most ...
Gianotti–Crosti syndrome (/ dʒ ə ˈ n ɒ t i ˈ k r ɔː s t i /), also known as infantile papular acrodermatitis, [1] papular acrodermatitis of childhood, [1] and papulovesicular acrolocated syndrome, [2]: 389 is a reaction of the skin to a viral infection. [3] Hepatitis B virus [4] and Epstein–Barr virus are the most frequently reported ...
This is a viral infection of the skin that usually presents in children ages 1–10 and immunocompromised patients. [12] The main symptom of this disease is round, hard, flesh colored, painless bumps, with sunken centers that are apparent on the surface of the skin (Figure 1).
