Viral skin infections are caused by various viruses and are generally contagious. They can occur at any age, with some conditions affecting children more frequently, and others being more common in sexually active adults. Prevention through vaccination, personal hygiene, and avoidance of contact with infected individuals—as well as timely diagnosis and appropriate treatment—are essential to avoid complications and further transmission.
Molluscum Contagiosum
A mild viral skin infection caused by the Molluscum contagiosum virus. Transmission occurs primarily through direct contact with infected individuals or contaminated objects (e.g. clothing, towels). It presents as small, skin-colored or pink papules. It is more common in children and immunocompromised individuals. Although the condition typically resolves within a few months, laser therapy may be required in some cases.
Herpes Simplex
Herpes simplex virus (HSV) is classified into two types: HSV-1, which usually affects the face and lips, and HSV-2, which primarily affects the genital area. Herpes is among the most widespread viral infections globally. It manifests as clusters of painful vesicles accompanied by burning and discomfort. The virus is transmitted via direct contact with lesions or saliva and can spread even in the absence of visible sores. Frequent recurrences are linked to reactivation of the virus, often triggered by stress, fatigue, or immunosuppression. Treatment involves antiviral agents that reduce the duration and severity of symptoms.
Varicella (Chickenpox)
A highly contagious childhood illness caused by the Varicella Zoster virus. Transmission occurs via respiratory droplets or direct contact with skin lesions. Key symptoms include fever and a widespread vesicular rash that crusts over time. Although typically mild, it may cause complications in immunocompromised individuals or pregnant women. Treatment is supportive, focusing on symptom relief and complication prevention. Vaccination is available for disease prevention.
Herpes Zoster (Shingles)
Caused by the reactivation of Varicella Zoster virus—the same virus responsible for chickenpox. After the primary infection, the virus remains dormant in nerve ganglia and may reactivate years later, particularly in the context of immune suppression. Herpes zoster manifests as a painful, unilateral vesicular rash arranged in a dermatomal distribution (a “belt-like” pattern). The vesicles eventually rupture and crust. Although not life-threatening, shingles can lead to severe complications, such as postherpetic neuralgia (chronic nerve pain). Treatment includes antiviral medication and analgesics for pain management.
Warts & Genital Warts (HPV)
Caused by the human papillomavirus (HPV), warts (verrucae) are benign skin growths, while genital warts are hypertrophic lesions typically found on mucous membranes of the genital area. Warts most often appear on the hands and feet, while genital warts are transmitted sexually and associated with an increased risk of cervical cancer. Common wart treatment includes cryotherapy or CO₂ laser ablation. Genital warts usually require antiviral therapy and CO₂ laser vaporization.
