Filiform warts are caused by human papillomavirus (HPV) infection, which is quite contagious. Transmission between spouses can be more severe due to prolonged contact, or sharing items like towels and bath mitts, which can lead to infection. Once one person is infected, it is crucial to seek standardized treatment at a hospital. The most common treatment currently used is laser removal, which in most cases can cure the condition in one or two sessions. However, some patients may experience recurrent outbreaks, requiring laser treatment each time to prevent the warts from multiplying and spreading. During treatment, towels and bath mitts should be frequently disinfected and not shared. Additionally, it is recommended to engage in regular exercise to boost the immune system, or take oral medications that enhance immunity to prevent recurrence.
