HPV infection may also cause more serious conditions, such as certain types of cancer. A person can be infected with more than one HPV strain at a time. Strains are identified by number and fall into either of the following two categories. These strains have no association with cancer but can lead to genital warts. In addition to the vulva and the penis, warts may appear on the cervix or vagina in women, the scrotum in men, or in and around the anus in men or women.
Warts may also appear in the mouth and throat. Two strains of HPV, types 6 and 11, cause 90 percent of these warts. In other words, they pooled data already gathered from 5, HIV-positive women in 20 smaller studies, and conducted a large-scale analysis. The data were also compared to published information from previous studies in HIV-negative women. The research team looked at the following questions:. The team studied the differences between women with three different levels of cervical cell abnormalities:.
The study found that over one-third of all HIV-positive women without cellular abnormalities As would be expected, HPV infection was more likely in women with more advanced cervical cell abnormalities. However, many more of the HIV-positive women Findings were as follows:.
HPV was found in Different subtypes also varied between regions. HPV16 - the subtype most likely to lead to cervical cancer — was the most common HPV subtype, found in It was more widespread among women with higher-grade cell abnormalities.
This meta-analysis presents a large amount of complex data on different types of human papilloma virus and their effects on HIV-positive women. What are the latest medical advancements for HPV prevention? Where can I find more information about HPV and safer sex? Human papillomavirus, or HPV, is a virus that infects the skin and genital area. More than types of HPV have been identified.
Some infect the skin and can produce warts, some infect the genital area and can produce genital warts, and some infect the genital area and can lead to cancer of the cervix, the opening of the uterus. They can also cause cancers of the vagina, vulva, penis, anus, mouth and throat. When the HPV virus is in contact with human cells, it may cause changes to the cell. These changes are called lesions. High-risk oncogenic HPV types are able to integrate into the DNA of the cell and modify its behaviour in a way that can result in cancer.
High-risk HPV are the cause of nearly all cervical cancers. They can also cause cancers of the anus, penis, vagina and vulva. There is growing evidence that high-risk types may also be involved in some cancers of the mouth and throat. Conversely, low-risk HPV types do not cause cancer. Some low-risk HPV types can cause genital warts these are called condyloma and other low-risk types cause lesions that are of no medical consequence or cause no lesions at all.
Although people might feel uncomfortable having warts in their genital region, these lesions are not life threatening and rarely present health complications.
Condyloma can develop very quickly or very slowly, they may be undetectable to the eye and they may clear up without treatment. HPV viruses are very common. HPV is most common in young women and men who are in their late teens and early 20s. HPV can be transmitted through skin-to-skin sexual contact, whether or not there is penetration. It can be transmitted through vaginal or anal intercourse, oral sex and mutual masturbation genital touching. The vaginal and anal tracts are particularly susceptible to sexually-transmitted HPV and the risk of transmission is greatest during penetration without a condom.
This being said, HPV is also found on parts of the body such as the vulva, scrotum and inner thighs which are not covered by a condom. It is thus possible to for partners to transmit HPV even when a condom is used. HPV can be transmitted through vaginal sex, anal sex, oral sex, or skin-to-skin contact of the genitals.
