Warts can be frustrating, especially on visible areas like the face, hands, or feet. In Hong Kong’s hot and humid climate, frequent sweating and prolonged skin moisture may increase the risk of developing warts. Public spaces like locker rooms also make spreading the virus easier. Preventing and treating warts can help you manage them effectively and reduce their impact on daily life.

What Are Warts?

Warts are benign, noncancerous growths that develop when HPV infects the outer layer of the skin. HPV is the primary cause of warts, but only a few of its 100+ strains lead to wart growth. They are among the most common viral skin conditions, affecting an estimated 10%of the global population. Some types of HPV cause warts on the hands and feet, while others are responsible for genital warts, which are sexually transmitted. Although warts are not medically serious, they can be bothersome. Depending on their size and location, they may cause discomfort, affect self-esteem, and even make everyday tasks such as walking or wearing shoes uncomfortable.

-

What Does a Wart Look Like?

Warts vary in appearance depending on their type and location. Some are dome-shaped, while others are flat or rough with a bumpy texture. Certain types resemble small calluses or cauliflower-like clusters. They can be flesh-colored, white, pink, or slightly brown, blending with the skin's natural tone. Small black dots may sometimes appear on the wart’s surface as these are clotted blood vessels supplying nutrients. The size of warts can also vary, from a few milimeters to several centimeters in diameter.

-

Are Warts Contagious?

HPV spreads readily through direct and indirect contact, so warts are considered highly contagious. The virus can pass from one person to another through skin-to-skin contact, such as handshakes or touching an infected area. It can also spread indirectly through shared objects, like razors, towels, gym equipment, or footwear. Even minor skin abrasions make it easier for HPV to enter the body, increasing the risk of developing warts. Public spaces like swimming pools provide ideal conditions for spreading the virus, especially when people walk barefoot on damp surfaces.

-

Where Do Warts Normally Appear?

Warts can develop anywhere on the body but most commonly affect the hands, feet, and genital area. Each type has distinct characteristics that come with it, requiring different treatment and prevention strategies.

-

Hands and Fingers (Common Warts)

Warts on the hands and fingers, also known as common warts, are frequently seen. These warts have a rough, grainy surface and often develop around the fingernails or joints, where the skin experiences regular pressure and movement. They can cause mild pain, especially when they grow near the nail bed, making simple activities like writing or typing uncomfortable. Common warts spread quickly through direct contact with contaminated surfaces, such as doorknobs, shared pens, or towels.

-

Treatment and Prevention of Common Warts

Over-the-counter remedies like salicylic acid work by gradually peeling away infected skin layers. Cryotherapy is used for more persistent warts, in which liquid nitrogen freezes and destroys the wart. Laser therapy is another option.

-

Good hand hygiene is the first step to preventing common warts. Keeping hands clean and moisturized helps maintain a strong skin barrier, reducing the risk of HPV entering through small cuts or abrasions. Avoiding direct contact with infected surfaces, such as touching door handles with tissue, can also lower the chances of getting warts. If you already have warts, covering them with a bandage can prevent their unintentional spread to other parts of your body.

-

Foot Warts (Plantar Warts)

Foot warts, also known as Plantar Warts, develop on the feet's soles, heels, or balls. Unlike common warts, which grow outward, plantar warts tend to grow inward due to the pressure from walking and standing. This can cause significant discomfort or pain, especially if the wart forms on a weight-bearing area.

-

Plantar warts are highly contagious and spread through direct contact with HPV, often in warm, moist environments. The virus thrives in public swimming pools, locker rooms, and communal showers. Walking barefoot in these areas increases the risk of infection, especially if the skin has minor cuts or abrasions. Because plantar warts can be stubborn and painful, early treatment can help manage symptoms and prevent them from spreading further.

-

Treatment and Prevention of Plantar Warts

Plantar warts have treatment options similar to common warts, including salicylic acid to break down the wart tissue or cryotherapy to freeze and remove it. If they persist or cause significant discomfort, doctors may recommend other treatments, such as laser therapy or minor surgical removal.

-

Since plantar warts are commonly contracted in damp environments, prevention focuses on foot hygiene and protective measures. To help reduce the risk of infection, feet should be kept clean and thoroughly dried, especially between the toes. Walking barefoot in public areas such as swimming pools and locker rooms increases the likelihood of exposure to HPV, so wearing sandals or flip-flops in these spaces is essential. It’s also advised not to share footwear, socks, or towels.

-

Genital Warts

Genital warts are a type of skin infection that appears on or around the genitals and anal area. They are primarily transmitted through direct skin-to-skin contact during sexual activity. Unlike common warts, genital warts tend to be softer and flesh-colored, sometimes forming clusters that resemble small cauliflower-like growths.

-

Symptoms may appear anywhere from two weeks to eight months after exposure to the virus. In men, genital warts often develop as small, painless lumps on the penis, scrotum, or around the anus. In women, they typically form on the vulva, inside the vagina, or around the cervix, sometimes causing itching or mild discomfort. While genital warts are not life-threatening, they can be persistent and may require medical treatment to remove.

Treatment and Prevention of Genital Warts

Unlike other types of warts, genital warts generally require medical attention. While they cannot be permanently cured, treatments can help remove visible growths and manage symptoms. Doctors may recommend cryotherapy or electrocautery, which involves burning off the warts with an electrical current. Prescription creams stimulate the immune system and help the body fight the virus.

-

Preventing genital warts can start with practicing safer sex. Using condoms consistently and properly can reduce but not eliminate the risk of HPV transmission. Only having one sexual partner who is not infected and who is only having sex with you will drastically reduce the probability of contracting genital warts. It’s essential to receive the HPV vaccination to prevent genital warts and also cervical cancer. Keeping the genital area clean and avoiding scented soaps or bath oils can prevent irritation and further discomfort.
