Josephine feels that Elizabeth is being far too graphic, but Elizabeth wants her information to be highly effective and visually dramatic, so she is going to leave it up to the doctors to decide. She talks to people about STDs almost every day and everyone seems to have the impression that the person they are intimate with doesn’t have an STD, or that because this is a small town STDs are not really a problem, or that it just won't happen to them. She really wants to dispel these notions. Just in case Josephine is correct, Elizabeth decides to start over with the basic facts first. Genital warts are caused by __________.

STDs are sexually transmitted disease that are more often transferred through the sexual contact. They are the common contagious disease that affects the human population.

Genital warts are marked by the pink or brown swellings near the genital area. They can occur on any reproductive part of the body. The causative agent of the warts is the human papilloma virus and can be converted into cancer if left untreated.

Thus, the answer is human papilloma virus.
