Plantar Warts

Warts are small benign growths that develop on the skin due to a viral infection caused by the human papillomavirus (HPV). HPV affects 80-90% of the global population, with most individuals remaining asymptomatic. Plantar warts occur in 10% of the general population and 20-30% of school-aged children. Initially appearing as small, circular growths, they can gradually increase in size over time and may become either symptomatic or asymptomatic.

There are several risk factors for plantar warts. A weakened immune system makes it harder to fight off infections, while cuts or breaks in the skin provide an entry point for the virus. Direct contact with HPV particularly in communal areas like swimming pools, can increase the risk of infection. 

Age also plays a role, as children and teenagers are more susceptible. A previous history of warts increases the likelihood of recurrence, and poor foot hygiene can contribute to the development of plantar warts. Excessive moisture, such as sweaty feet, can create an ideal environment for the virus to thrive.
