Step-by-step explanation:
The condition described in the question pertains to plantar warts, which are flat, hard, thick growths on the soles of the feet. These are caused by certain strains of the human papillomavirus (HPV). Unlike genital warts, which are a sexually transmitted infection manifesting on the genitals, plantar warts occur on the feet and can be quite painful because they often grow inwards due to the pressure of walking. HPV is a virus with many different types that can also lead to other types of warts like flat warts, common warts, and filiform warts, as well as more serious conditions such as cervical cancer.
