Human Papillomavirus ( Hpv ) Family

What is the Human Papillomavirus? Commonly known as HPV, it is an infection that spreads through sexual contact. There are over one hundred different types of HPV; several types cause genital warts, while other high risk strands can lead to cancer of the cervix, anus, vagina, and penis. Because HPV is often asymptomatic, many people are unaware of their infection status, and thus, their potential for transmitting the virus to a sexual partner. The significance of the Human Papillomavirus is that fifty percent of Americans who are sexually active will contract it within their lives, and at any given point there are twenty million Americans already infected with it (“By the numbers: HPV Vaccine”).

Human Papilloma Virus, more commonly known as HPV, is a sexually transmitted virus. It is spread from skin-to-skin contact with an infected person, typically during sexual encounters. It is the most common sexually transmitted disease in the United States. According to the Immunize Action Coalition, “most sexually active American men and woman will contract at least one type of HPV virus during their lifetime” (A Parent 's Guide to Preteen, 2013, p. 1). To put the numbers in perspective, it infects an estimated seventy-nine million Americans today with approximately fourteen million more people being affected additionally each year (Human

HPV stands for the human palliloma virus. It is estimated that there are around 100 different types of HPV. The HPV virus can cause lesions to develop on the soft palate, tonsils and tongue. It can also increase the risk of certain forms of cancer, including oral cancer and cervical cancer.

Human Papillomavirus(HPV) is the most common sexually transmitted infection in the United States, according to Centers for Disease Control and Prevention(CDC) around 20 million people are infected with HPV and additional 6.2 million people are newly infected every year. According to National Health and Nutrition Examination Survey in 2003-2004 among sexually active women (57% of 14 to 19 years and 97% of 20 to 59 years) HPV was highest prevalent in youngest age group (40% of 14-19 years and 50% of 20-24 years). Infection rates decrease after age of 24 years. There are more than 100 types of HPV viruses out of which 40 cause genital infections. Out of

HPV is a class of more than 150 related viruses. Each HPV virus in this vast body receives a number which is called its HPV type. HPV is termed for warts (papillomas) some HPV types can cause. Some other HPV types can lead to cancer. HPV cancers consist of cancer of the cervix, vulva, vagina, penis, or anus. HPV infection can also cause cancer in the

Human Papillomavirus (HPV) is a double -stranded deoxyribonucleic acid (DNA) virus that only infects humans with an attraction to both cutaneous and mucosal surfaces such as the cervix, anus, tonsil, and oropharynx (Clark, 2013). HPV is a type of oncogenic virus that goes into the cells and can cause several diseases. Over the years, research has surfaced connecting genital HPV to several types of cancer. There are over a hundred strains of HPV but the most high risk strains, 16 and 18, have been shown to cause vulvar, vaginal, anal, and the most concerning, cervical cancer (Chan, Ng, & Wong, 2012). Genital HPV

Human papillomavirus (HPV) is made up of double stranded DNA with a capsid. Their viral genome is consisting of such as early (E) gene like E6 and E7encodes for oncoproteins and late (L) gene such as L1 and L2 encodes for structural proteins like capids. There are more than 100 different types of HPV identified and they generally infect around cutaneous or mucosal areas. HPV viral genome can be categorized into low risk (LR) and high risk (HR). High risk types such as HPV-16 and -18 are ones that can develop into cancer and other tumors mostly in genital area or a head and neck squamous cell. Low risk types such as HPV-6 and -11 are more frequently found I larynx or genital area (Klozar et al., 2010). Therefore, careful evaluation such as risk factors, or possibly a new vaccination to prevent against HPV related to oropharyngeal SCC should be questioned in public health

Human Papilloma Virus (HPV) accounts for the third most prevalent cancer in females worldwide,15 as it is the most common sexually transmitted infection (STI).2 There are more than 100 subtypes of HPV; 16 of those subtypes are known to be high-risk.15 HPV is a crucial precursor to cervical cancer in 99.8% of those affected,2 with subtypes 16 and 18 being the most common types.15

Cervical cancer is formed in the tissues of the cervix, an organ that connects the uterus and the vagina. Virtually all cervical cancers are caused by Human papillomavirus (HPV) infections (Schiffman et. al., 2007). HPV is the most common sexually transmitted infection in the United States. According to the CDC, 75% of sexually active people aged 15-49 have the infection at some point in their lives. (CDC). Because HPV infection is usually asymptomatic, infected people do not know exactly when they get the infection. In most cases, the body is able to fight off the virus before any symptom. However, health problems such as genital warts and cancer may

There are 200 different strands of the HPV virus. Forty types are spread through sexual contact. The good news is that most people who contract the HPV virus will not have any adverse health effects. However, nearly all cervical cancer cases are linked to the HPV virus. Cervical cancer kills 3,710 women each year. The HPV virus can also cause oral cancer.

Hpv is a virus that produces epithelial tumours in both the skin and mucous membranes2, however these tumours have different probabilities of forming cancers according to the subtype of the virus causing the infection for example tumours due to Hpv 16, 31, and 70 have a high probability of forming tumours where as Hpv 84 has a much lower risk of turning the tumour malignant3.

HPV lives in the body’s flat and thin cells on the skin’s surface called epithelial cells (“Information About the Human Papillomavirus”). There are more than 200 related viruses

Human Papilloma Virus (HPV). HPV infection Is a sexually transmitted disease (STD) caused by 30 to 40 of 130 or so strains of Human Papilloma Virus.

The HPV genome is a double-stranded circular DNA which is approximately 8 kb (7200-8000 base-pair) long (Figure 1).1 HPV DNA can be divided into early (E), late (L) and long control (LCR, non-coding) regions.1 These regions are separated by two (early and late) polyadenylation (pA) sites.1 The early region constitutes more than 50% of the total viral genome and includes six open reading frames (ORFs) that encodes E1, E2, E4, E5, E6 and E7 viral proteins.2 The late region, located downstream of the early region, forms 40% of the viral genome, and has L1 and L2 ORFs which encodes major (L1) and minor (L2) viral capsid proteins. LRC forms 10% of the viral genome, and it is a non-protein

HPV is a non-enveloped virus with double-stranded DNA that is protected by an icosahedral capsid. An icosahedral is a polyhedral with twenty faces. The genome consists of double-stranded circles with approximately eight-thousand base pairs containing eight or nine open reading frames. Gene expression involves multiple promoters and complex patterns of splicing. The HPV genome separates into three regions; the long control region, early region, and a late region. The early region contains no coding for structural proteins in
