What is a wart?
A wart is a skin infection that is caused by a virus in the layers of your skin that can spread to other parts of the body. It is easily missed for many reasons. First, it takes a while for the wart to be noticeable; a wart can take a month before growing to a detectable size. Second, they are easily missed because warts have relatively the same color as your skin. Third, warts are generally not painful if not located on areas of your feet that are pressed on the ground.
It is good to know that despite common belief, warts (especially ones on the foot) do not go away on their own. This is because the foot has an extra layer of skin, which gives room for the wart to cozily nest in your skin and spread around, instead of falling off.
What causes warts?
Warts occur because of microscopic openings in our skin that are exposed to the virus while walking barefoot. It is easy to catch a wart if you have been walking barefoot in public places such as pools, changing rooms, public showers, hotel rooms, and shoe stores.
In the case that you have sweaty feet, this makes the wart worse; it spreads easily in a moist environment.
