### Types of Warts Caused by HPV 1. **Common Warts**: These are rough bumps that usually appear on the hands. They are small, ranging from the size of a pinprick to a pencil eraser, and may have tiny black dots which are dead blood vessels. They are caused by HPV types 2 or 4. 2. **Plantar Warts**: Found on the soles of the feet, these warts are flat and may have small clotted blood vessels that look like tiny black dots. They can grow deeper into the foot and become painful. They are caused by HPV types 1, 2, 4, 27, and 57. 3. **Mosaic Warts**: These are flat, white, pinhead-sized marks that appear on the balls of the feet and under the toes. They are caused by HPV type 2. ### Treatments for Warts - **Freezing (Cryotherapy)**: Liquid nitrogen is used to freeze the wart, which may take several treatments. This can be painful and may cause blistering or scarring. - **Cantharidin**: A liquid applied by a doctor that causes a blister to form around the wart, cutting off its blood supply. The dead wart is then removed by the doctor. - **Medications**: Prescription-strength salicylic acid, bleomycin (injected into the wart), and imiquimod (an immunotherapy drug) are used to treat warts. For children, 5-fluorouracil may be an option. - **Surgery**: When other treatments fail, a doctor can surgically remove the wart, which may leave a scar. - **Laser Surgery**: Uses a laser to burn and destroy wart tissue, which can also leave a scar. - **Home Remedies**: Over-the-counter salicylic acid treatments, freezing sprays, and duct tape (though not highly recommended) can be used at home. ### Prevention Methods - **Avoid Touching Warts**: Do not touch warts on yourself or others to prevent spreading the virus. - **Keep Skin Clean and Dry**: Moist and damaged skin is more susceptible to HPV. - **Use Protection**: Use condoms or dental dams during sexual activity to prevent genital warts. - **Boost Immune System**: A healthy immune system can help fight off HPV. - **Vaccination**: HPV vaccines can protect against the types of HPV that cause most warts. If you have diabetes or a weakened immune system, consult a doctor for proper treatment and avoid self-treatment.
