👉 Verrucella is a fungal infection that affects the skin, causing blisters or ulcers on the affected area. It usually occurs in warm and moist environments such as indoor bathrooms, swimming pools, or hot showers. The fungus, which can be either pathogenic (causing disease) or non-pathogenic (not causing disease), grows by reproducing through hyphae. This process can cause severe inflammation and infection in the affected area, leading to blisters that may itch or scab
