Introduction

In general, filiform warts are not caused by high-risk HPV infections; they result from low-risk HPV infections and are distinctly different from high-risk HPV types that may cause cancer in terms of both type and severity. There is no need to be concerned about health risks related to high-risk HPV in daily life. If filiform warts are detected, they can be removed through methods such as freezing or laser treatment, and personal hygiene should also be maintained.

Generally, filiform warts do not belong to conditions caused by high-risk HPV infections. They are caused by low-risk HPV infections and are distinctly different from high-risk HPV types that may cause cancer in both viral type and degree of harm. Detailed analysis is as follows:

From HPV typing perspective, the viruses causing filiform warts are mostly low-risk subtypes such as HPV 1, 2, 4, etc. These subtypes mainly affect the epidermal layer of the skin, only stimulating abnormal proliferation of skin cells and forming benign filiform skin growths. They do not invade deeper layers of the skin nor cause malignant transformation of cells. The health risks are mainly concentrated on aesthetic impact and localized transmission. In contrast, high-risk HPV types can invade inside cells, interfere with the normal growth cycle of cells, and long-term infection may lead to carcinogenesis.

Daily concerns about health risks associated with filiform warts and high-risk HPV are unnecessary. If filiform warts are detected, they can be removed through freezing, laser therapy, or other methods. At the same time, maintaining personal hygiene, avoiding sharing personal items, reducing the probability of virus transmission to others, and maintaining skin health are all important preventive measures.

What causes the growth of filiform warts?

Under normal circumstances, the development of filiform warts may be caused by factors such as weakened skin barrier function, prolonged friction on localized skin areas, infection with low-risk types of human papillomavirus (HPV), spread of flat warts, or evolution from common warts. It is recommended to seek timely medical attention, identify the underlying cause, and undergo symptomatic treatment under a doctor's guidance. In daily life, it is important to maintain skin cleanliness, avoid scratching affected areas with hands, and prevent the spread of the virus.

What is the best ointment for treating filiform warts?

Under normal circumstances, there is no definitive answer to the question "what topical medication is best for treating filiform warts," as treatment effectiveness may vary among individuals. Commonly used topical medications include tretinoin cream, imiquimod cream, fluorouracil ointment, salicylic acid ointment, and interferon gel, which should be appropriately selected based on individual circumstances. Tretinoin cream works by regulating epidermal cell growth and promoting the shedding of warts.

Do filiform warts spread to family members?

In general, filiform warts can be contagious to family members, but not all contact leads to transmission. The likelihood of transmission depends on factors such as the mode of contact and the skin condition of family members. It is important to avoid direct or indirect close contact in daily life to reduce the risk of infection. To minimize the risk of transmitting the infection to family members, patients should use personal hygiene items separately and regularly wash and disinfect towels, clothing, and other items.
