Warts are caused by an infection with certain types of human papillomavirus (HPV). The virus enters the top layer of the skin through tiny cuts or broken skin, leading to rapid and excessive growth of keratin, a hard protein, which forms the wart. Warts can spread through direct contact with a wart or by touching objects contaminated with the virus, and they are especially common in children, people with weakened immune systems, and those who handle raw meat regularly.
Why We Get Warts
The main reason for getting warts is the presence of HPV on or around the skin. When the virus infects the epidermis, it causes the skin cells to multiply quickly, creating a thick, rough growth called a wart. People are more likely to get warts if they have cuts, scrapes, or damaged skin that allow the virus to enter easily. Warts tend to appear more in moist or soft areas of the skin, and they are contagious, so contact with someone else's wart or contaminated surfaces can transfer the virus and cause new warts to grow.
Summary
- Warts are caused by the human papillomavirus (HPV).
- The virus infects the outer layer of the skin through tiny cuts.
- This causes the skin to grow rapidly, forming a wart.
- Warts are contagious and can spread via direct skin contact or contact with contaminated objects.
- More common in children, immunocompromised individuals, and those with skin injuries.
