If you have warts on your feet, you may still be infected with HPV. Although you have had a plantar wart on your feet, and the wart has been removed through certain treatments, it is possible for your skin to be re-infected with HPV again because HPV is clinically classified into a variety of subtypes, and although you have been infected with a subtype, you may be able to have some immunity for this subtype of HPV in the future, but it doesn’t mean that you have immunity for the other subtypes of HPV. HPV has immunity, so it is still possible to be infected. Some patients may be susceptible to specific HPVs due to individual differences, and from this point of view, they are also susceptible to HPV infections, and if they have a history of infection, they should pay attention to skin protection.
