Warts (verruca) occurs due to human papillomavirus (HPV). HPV is a sexually transmitted infection (STI). it can spread by direct and indirect contact.

Warts don’t show up immediately after virus exposure. Sometimes it takes as long as six months to appear after HPV exposure.

People with strong immunity may not notice any warts even after HPV exposure. This is because their body’s immune system fights well against this virus.

Warts are painful to touch. When they occur in feet, it’s painful to walk then. Warts usually go away on their own, but it takes time.

Wart and corn are quite similar. Wart is small bumps with, grainy appearance. If you touch the wart, it would feel rough, and you can notice a black spot on the top of the wart.

Warts can be white or flesh color with a black dot on the top.
