Warts are benign skin growths caused by the human papillomavirus (HPV). There are over 100 strains of HPV, and different strains cause different types of warts. Warts are contagious and spread through direct skin contact or shared objects, but they often resolve on their own as the immune system fights the virus. However, they can persist, spread, or cause discomfort, prompting treatment.
Most warts are harmless, but genital warts are a sexually transmitted infection requiring medical attention. Below are the six most common types, including their signs, symptoms, and options for home remedies and professional treatments.
1. Common Warts (Verruca Vulgaris)
Common warts are rough, raised bumps that typically appear on hands, fingers, knees, or elbows. They often have a grainy surface with tiny black dots (clotted blood vessels).
**Signs and Symptoms:**
– Firm, raised growths with a rough texture
– Grayish-yellow or brown color
– May appear singly or in groups
– Usually painless, but can be tender if on pressure points
2. Plantar Warts
Plantar warts grow on the soles of the feet, often pushed inward by body weight. They can be painful when walking.
