Introduction

Filiform warts are generally not dangerous and are mostly benign lesions that primarily affect appearance. Malignant transformation is rare, but the warts may gradually increase in number or be transmitted to others, so attention to daily protection and management is necessary. It is important to avoid scratching the warts, not share personal items with others, and take measures to reduce the risk of spread and transmission. If the number of warts is large or they affect daily life, they can be removed through standard treatments such as cryotherapy or laser therapy.

Generally, filiform warts are not dangerous and are mostly benign lesions that mainly affect appearance, with very rare malignant transformation. However, they may gradually increase in number or be transmitted to others. Attention should be paid to daily protection and management. Detailed analysis is as follows:

From the perspective of health risks, filiform warts are caused by infection with low-risk types of human papillomavirus. These viruses do not cause malignant tumors and, in most cases, only form slender skin growths on the skin surface. They do not damage internal organs or cause significant discomfort, although warts located on exposed areas such as the eyelids or neck may affect appearance.

However, filiform warts carry a risk of spreading. If the warts are frequently scratched, the virus may adhere to the hands and subsequently spread to other parts of the body, leading to the appearance of new warts. Sharing towels, clothing, or other personal items with family members may also transmit the virus to others.

In daily life, it is important to avoid scratching filiform warts and not to share personal items with others to reduce the risk of spreading and transmission. If there are numerous warts or they affect daily life, they can be removed through standard treatments such as cryotherapy or laser therapy. After removal, it is important to keep the local skin clean and dry to promote wound healing and prevent infection.

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.
