Parents have been hand-over-foot asking me questions about their child's warts.
Let me see if I can do more than skin the surface on this topic.
Warts are tiny skin infections caused by a strain of human papilloma virus — but not the same strain that causes genital warts and increases one's risk for cervical cancer in teen and adult women.
The HPV strain that causes common warts results in small, hard bumps on your skin with a rough surface — similar in texture to a cauliflower. They are usually found on the fingers, hands, arms and feet in children and are painless except for those on the feet.
More than 50 percent of children will get a wart at some time. They are usually passed from person to person by simply sharing towels or from close contact between children who may have open scratches or cuts, allowing the virus to spread easily into someone else.
The good news is that warts can be treated and will go away even without treatment, although this may take weeks to months or even years. Over-the-counter medications that contain mild acids that will slowly peel off the wart's dead skin cells and eventually cause it to disappear are available.
One of the most recent discoveries in wart treatment involves the use of duct tape. A few studies suggest that wrapping the wart in duct tape for six days and then soaking and paring down the wart with an emery board or pumice stone and repeating for four to eight weeks may be just as effective as the over-the-counter acid medications. The duct-tape method is thought to work by revving up the body's immune system, as the tape mildly inflames the wart, but more evidence is needed to determine just how effective this therapy can really be.
