What is HPV?
HPV stands for human papillomavirus. There are 40 types of genital HPV infection. The virus infects the genital area, such as the skin of the penis, vulva (area outside in vagina), the anus and the linings of the vagina, cervix, and rectum.
How common is HPV?
Genital HPV is the most common sexually transmitted infection. According to the Centers for Disease Control, 20 million Americans are currently infected with HPV, and another 6.2 million people become newly infected each year. The Centers for Disease Control also notes at least 50 percent of sexually active men and women will have a genital HPV infection in their lives.
How can you tell if you have HPV?
There are two types of HPV, low-risk and high-risk. According to womenshealth.gov, low-risk HPV can cause genital warts, weeks, months, or years after sexual contact with an infected person.
In women, warts form:
- Inside and around the outside of the vagina
- On the vulva ("lips" or opening to the vagina) cervix, or groin
- In or around the anus
In men, genital warts can grow:
- On the penis
- On the scrotum, thigh, or groin
- In or around the anus
In rare cases, genital warts can grow in the month or throat of a person who had oral sex with an infected person.
Genital warts can vary in appearance. They may be bumpy or flat or so small that they can not be seen. Warts can cause discomfort, itching or burning. However, not everyone infected with HPV gets warts or any other symptoms.
High-risk HPV, the type that causes cervical cancer, can be found during Pap tests. Since many women with HPV infections do not know their status, it is important to maintain a yearly schedule of Pap tests.
While HPV is as common in men as women, it rarely is the source of health problems in men. However, it can lead to anal cancer in men who have sex with men.
What are the treatments for HPV?While there are treatments for genital warts and changes to the cervix created by HPV, there is no treatment or cure for HPV.
How can HPV be prevented?
- Abstain from sexual contact
- Keep your sexual relationship monogamous
- Use a condom every time for vaginal, anal, or oral sex. While condoms are not 100 percent effect in preventing HPV, they reduce the risk for a variety of sexually transmitted diseases.
What about the vaccine?
The HPV vaccine known as Gardasil® has some limitations. Currently, the vaccine is given to females between the ages of nine to 26. It protects against four of the 40 types of HPV. According to studies, it is effective in preventing 70 percent of cervical cancers, if females are fully vaccinated (three doses) before they have sex for the first time. The protection lasts for five years.
