Transcript of HPV

As the virus enters a cell, the L1 protein coat degrades, leading to the release of the virus' genetic material in a cell's nucleus. In the nucleus, the DNA from the virus is transcribed by messenger RNA, which carries viral DNA snippets to the cellular DNA, where it is integrated and eventually translated into proteins called E6 and E7, which can lead to cancer There are more than 40 HPV types that can infect the genital areas of males and females. These HPV types can also infect the mouth and throat. Most people who become infected with HPV do not even know they have it. Hpv Fact: HPV is passed on through genital contact, most often during vaginal and anal sex. HPV may also be passed on during oral sex and genital-to-genital contact. HPV can be passed on between straight and same-sex partners. HPV stands for Human Papillomavirus which is a virus from the papillomavirus family that affects human skin and the moist membranes that line the body, such as the throat, mouth, feet, fingers, nails, anus and cervix. What is HPV? Human papillomavirus HPV is normally asymptomatic in males
The HPV test is available only to women; no HPV test yet exists to detect the virus in men. However, men can be infected with HPV and pass the virus along to their sex partners.
Vinegar solution test: your doctor may apply a vinegar solution that turns HPV-infected genital areas white.

Pap test: Your doctor collects a sample of cells from your cervix or vagina to send for laboratory analysis. Pap tests can reveal abnormalities that may lead to cancer.

DNA test: This test can recognize the DNA of the high-risk varieties of HPV that have been linked to genital cancers. The test is conducted on a sample of cells taken from your cervix. Girls and women: Two vaccines (Cervarix and Gardasil) are available to protect females against the types of HPV that cause most cervical cancers. One of these vaccines (Gardasil) also protects against most genital warts. Gardasil has also been shown to protect against anal, vaginal and vulvar cancers. Vaccinations: Boys and men: One available vaccine (Gardasil) protects males against most genital warts and anal cancers. Gardasil is recommended for 11 and 12 year-old boys, and for males 13 through 26 years of age, who did not get any or all of the shots when they were younger. To Prevent any type of HPV, the most reliable way is to avoid skin-to-skin, oral, anal or genital contact with a person.

•Preventing Penile Cancers: There is no approved screening test to find early signs of penile cancer. HPV Prevention: More than half of sexual active people are infected with 1 or more HPV types at some point in there life. Recent research indicates that at any point in time 42.5% of women have genital HPV infections, whereas less than 7% of adults have oral HPV infections. HPV Statistic: There are 200 strains of HPV
but there are only two strains that causes
cancer.
HPV-16 and HPV18 Either Cervarix or Gardasil is recommended for 11 and 12 year-old girls, and for females 13 through 26 years of age, who did not get any or all of the shots when they were younger. These vaccines can also be given to girls beginning at 9 years of age. It is recommended to get the same vaccine brand for all three doses, whenever possible. Mayoclinic.com

•1,500 women who get HPV-associated vulvar cancer
•500 women who get HPV-associated vaginal cancer
•400 men who get HPV-associated penile cancer
•2,700 women and 1,500 men who get HPV-associated anal cancer
•1,500 women and 5,600 men who get HPV-associated oropharyngeal cancers (cancers of the back of throat including base of tongue and tonsils) [Note: Many of these cancers may also be related to tobacco and alcohol use.]
Certain populations are at higher risk for some HPV-related health problems. This includes gay and bisexual men, and people with weak immune systems (including those who have HIV/AIDS). Yearly Statistics: Genital warts usually appear as a small bump or group of bumps in the genital area. They can be small or large, raised or flat, or shaped like a cauliflower. Health care providers can diagnose warts by looking at the genital area during an office visit. Warts can appear within weeks or months after sexual contact with an infected partner—even if the infected partner has no signs of genital warts. If left untreated, genital warts might go away, remain unchanged, or increase in size or number. They will not turn into cancer. Warts: Corina
