A few years ago, my brother-in-law came down with warts on his hands. My niece, his daughter, developed warts on her hands within a year. Her mother speculated that they were caused by "hormones," since the girl was 14 at the time. Her mother subsequently began noticing warts on her own hands. Although I don't know very much about warts, I felt they were probably being caused by a virus, bacteria or some other contagion, otherwise they would not suddenly appear on three members of the same family.
A year ago, the father left his wife and child and came to live with his sister, another sister-in-law of mine. Her family now has warts. I am a little concerned about allowing my children to visit over there, since I don't want them to suddenly start sprouting warts hither and yon.
So, my questions are: Are warts contagious? If so, by what mechanism? Once a person develops warts, what is the most effective treatment with the least amount of medical input (my husband's family is full of people who believe blue-green algae will cure cancer/let them live forever/bring their vision back to 20-20, etc.)? Assuming someone pulls themselves together long enough to actually see a doctor, does anything a regular physician can do yield better results than over-the-counter treatments?
Thanks for your advice!
