After completing the treatment plan to rid your feet of warts, or verruca plantaris virus, it is important to work to prevent their return.  It is important to discourage the environment that harbored these viruses in the first place.  This includes keeping your feet as clean and moisturized as possible as small cuts in your foot act as entry points for new verruca viruses. Also, never go barefoot in public locker rooms, gyms, or showers; always use pool shoes or waterproof sandals.  Preventing sweat and excessive moisture to accumulate in your socks and shoes also prevents the virus from thriving, so using a sport sock with a cotton blend which wicks the moisture away from your skin.  Most importantly, if you think a wart may be returning, do not ignore it!  The faster you treat the virus, the faster it will go away.
