What is the primary cause of verrucae?

1. Fungal infection

2. Viral infection

3. Bacterial infection

4. Parasitic infection

The correct answer is: Viral infection

Verrucae, commonly known as warts, are primarily caused by a viral infection, specifically the human papillomavirus (HPV). This virus infects the skin and mucous membranes, leading to the characteristic growths associated with warts. HPV enters the skin typically through small cuts or abrasions and triggers an overproduction of skin cells, resulting in the raised, rough texture of verrucae. Understanding the nature of the causative agent is crucial, as it informs treatment options and prevention strategies. For instance, antiviral treatments or topical therapies may be employed to target the HPV infection. In contrast, fungal, bacterial, or parasitic infections would present with entirely different types of lesions and require different therapeutic approaches, which underscores the importance of accurate diagnosis in dermatological conditions.
