No they are not. They are NOT contagious, in that you do not catch them from other people.
For something to be infectious it has to be caused by a bug (bacteria, virus, fungus or parasite) that can be transmitted from one person to another. Corns on the foot are not caused by an infection so they can not be contagious. You can not pass them onto other people in the family, in communal showers or around swimming pools or anywhere else.
Corns on the foot are caused by too much pressure. They don’t have roots that they grow back from when removed. To treat a corn on the foot, that pressure that causes it needs to be removed.
The myth that corns may be contagious could arise because people get confused between corns and verrucae on the feet. A verruca (wart) is a small skin lesion that is caused by a virus, so can be passed on to other people. These are not corns. They are both small and both can be painful and can sometimes to the untrained eye look the same. If you are not sure if you have a corn or a verruca (wart), then get a podiatrist to check it out and advise the best course of action.
