🔍 Quick Summary
Warts are small, rough skin growths caused by a virus.
They are common, contagious, and usually harmless.
1️⃣ Introduction
Warts are non-cancerous growths on the skin.
• caused by human papillomavirus (HPV)
• can appear on hands, feet, or other areas
• common in children and young adults
👉 Warts are harmless but can spread if untreated.
2️⃣ How it happens
The virus enters through small breaks in the skin.
• infects the top layer of skin
• causes excess skin growth
• leads to rough, raised bumps
👉 Direct contact helps the virus spread.
3️⃣ Types

- rough, raised bumps
- often on hands and fingers
• Plantar warts
- occur on soles of the feet
- may be painful when walking
• Flat warts
- smooth, smaller
- often on face or arms
👉 Different types appear in different locations.
4️⃣ Common causes
• Direct contact
- touching infected skin
• Indirect contact
- shared surfaces (e.g. floors, towels)
5️⃣ Symptom
• small rough growths
• skin-colored or slightly darker
• may have black dots (tiny blood vessels)
👉 These are caused by viral stimulation of skin cells.
6️⃣ Associated symptoms
• mild pain (especially on feet)
• discomfort when pressure applied
• spreading to nearby skin
• cosmetic concern
👉 Often more noticeable than harmful.
7️⃣🩺When it becomes concerning 🚨

8️⃣ Management / treatment
• topical treatments (salicylic acid)

9️⃣ Diagnosis
