Plantar warts are caused by human papillomavirus (HPV), a highly contagious virus. The incubation period can range from 1-12 months, and while it's possible to catch the virus again, it doesn't mean the virus stays in your body forever. Treatment options include home remedies, over-the-counter treatments, and medical procedures like cryotherapy or surgical removal for severe cases. Practicing good hygiene habits and strengthening your immune system can help prevent plantar warts. Research may lead to more effective treatments but eradication of HPV remains far-fetched.
