Toe warts and corns are both skin diseases that occur on the feet, but they are entirely different diseases, and many people easily confuse toe warts with corns. First, the causes of toe warts and corns are different. The occurrence of corns is greatly related to compression and friction, while toe warts are mainly caused by viral infections due to reasons such as low immunity. Secondly, their contagiousness is different; corns are not contagious, while toe warts are highly contagious.

Differentiation between Corns and Plantar Warts

Corns and plantar warts are two different skin conditions, although both often occur on the feet, they have significant differences. First, corns and plantar warts differ in contagion and quantity. Generally, corns appear singly and are not contagious; while plantar warts often appear in larger numbers and are highly contagious. Moreover, corns are usually caused by pressure or friction on the feet, whereas plantar warts are caused by a viral infection of the skin on the soles of the feet.

Can I apply corn plaster if the corn has burst?

If a corn has broken open, you should not continue to apply corn plaster to it, as the plaster is somewhat corrosive. Since the skin of the corn has already been damaged, you should not use this medicated plaster until the skin has healed. Corns typically develop on the skin due to prolonged friction and pressure on the foot skin. Wearing ill-fitting shoes for a long period, or having deformed feet or toes, can also lead to the development of corns. If you have a corn, you can apply corn plaster locally, or visit a formal hospital to receive treatments such as cryotherapy with liquid nitrogen or using a carbon dioxide laser. If the corn has broken open, pay attention to the cleanliness and hygiene of the foot to prevent further infection. You can apply iodine locally for disinfection.

Are corns the same as calluses?

A corn is actually what is commonly referred to as a typical wart, and this type of common wart is actually caused by a viral infection. When the body's immune system is weakened, such an infection can occur, and it generally has a slight possibility of contagion. Most of the time, treatment of these warts involves localized injections of antiviral medication, or through methods such as laser surgery, which can achieve improvement. On the other hand, a callus is a type of localized proliferative condition, and although it may be caused by a viral infection, the likelihood of it being caused by localized pressure or irritation is greater. Typically, this condition can be improved through physical therapy methods, such as using topical medications to remove it, or by using laser surgery locally as a complementary treatment, achieving better outcomes.

Can corns be contagious?

Corns are not contagious; this condition is usually caused by prolonged friction and compression. Corns are characterized by thickened skin, commonly found on the soles of the feet, the front-middle parts of the toes, and the outer edges of the little toes. If corns develop, it is important to eliminate the cause. If there is long-term friction or compression on the feet, it must be avoided. Wear appropriate shoes to reduce pressure and friction. For treatment, you can apply corn treatment ointments. (For specific medications, please administer them under the guidance of a professional physician and do not self-medicate blindly.)
