Plantar wart is a solid, rough enlargement of the skin developed in the heel of the feet or other associated areas where the pressure is generated in excess during walking. Callus or hard skinned layer is formed at the inner side of the warts or just beneath the upper skin layer of the feet due to the excessive pressure or friction. Tenderness is a common symptom of this type of warts and are frequent in children. (1,2)

Plantar Warts Causes

Warts are the outcome of viral infection. The virus that is involved in developing the warts is Human Papilloma Virus (HPV). HPV has more than 100 types of strain and 1, 2, 4, 27 and 57 are the different strains that are responsible to cause of plantar warts.

The virus enters through the skin to skin contact and often penetrates in the blood stream via the damage in the skin surface. Warts are contagious infection and the infection favorably transmit in the moist places, like swimming pools or locker room floors, shower and gym, in these areas the chances of existence of “skin residue” is maximum and moisture helps to keep the virus alive.

Warts can affected in any skin types and in different body parts. ‘Planter warts’ are the specific types of warts which develop on the sole of the foot. For prevention, covered protective foot wear can be useful.

Children are more susceptible towards the plantar warts, as their immune system is in developing stage, which cannot fully defend body against different infectious agent. But adults with immunosuppressant diseases or therapies are also susceptible towards plantar warts. (2,4)
