Human Papillomavirus, or HPV, is a sexually transmitted disease that few teens have heard about or understand. Carter examines the history of warts and HPV and carefully describes who is at risk, what symptoms to watch out for, and how to prevent the spread of this highly contagious disease. HPV has reached near epidemic proportions in the United States and Canada, affecting many young people who may not be aware of its symptoms. Carter concludes the book by describing other diseases that HPV has been shown to increase, such as cervical cancers in women and anal cancers in men.
