Can flea bites cause a recurrence of flat warts?
Disease description:
I had several flat warts on my face a while ago, which were successfully removed with laser treatment at the hospital. However, I was bitten by fleas two days ago and have since developed a few lumps. I'm a bit concerned whether being bitten by fleas could cause a recurrence of the flat warts.

Flea bites may lead to a recurrence of flat warts. Flat warts are caused by human papillomavirus (HPV) infection and are primarily transmitted through direct or indirect contact. Fleas, as ectoparasites, may carry bacteria and viruses on their mouthparts. If the patient's skin is broken, fleas may enter the body through the wound, causing abnormal differentiation and proliferation of skin cells, thereby triggering flat warts. Particularly after flea bites, if itching occurs and the patient frequently scratches the affected area, skin damage may result, increasing the risk of recurrence of flat warts. Therefore, prompt treatment should be administered following a flea bite, such as disinfecting the affected area with an antiseptic solution like iodophor, and careful observation of skin condition is necessary. If discomfort occurs, timely medical consultation should be sought, and the treatment recommendations of the physician should be followed. Additionally, maintaining personal hygiene and avoiding further flea bites can help reduce the risk of recurrence of flat warts.
