Warts are small, raised growths on the skin that look like grains with a rough surface. Small, blocked blood vessels that resemble blackheads are often visible inside the wart.
HPV (human papillomavirus) is manifested through warts. You can get it through direct contact with an infected person: for example, if you shake the hand with a person who has a wart on his finger or the back of his hand.
However, you can get infected in other ways: through personal hygiene items (towels, washcloths, razors, eyebrow clippers) or through infected surfaces (doorknobs, locker room floors). Most often, the virus clings to affected or damp skin. But it can be extremely difficult to establish the moment of infection, because sometimes the wart appears only six months later.
Most often, people with weakened immune systems are infected with HPV. Among them:
• Children and adolescents. This is due to both age-related imperfection of the immune system and the fact that children are less careful and more often have wounds on the skin.
• Patients with autoimmune disease.
• Patients with HIV / AIDS or those who have recently undergone organ transplants.
