What does phv high-risk positive mean

HPV can also be called human papillomavirus, which is a relatively harmful sexually transmitted disease, which is what we often call genital warts. When a laboratory test is conducted, HPV positive appears on the test report, which means that the patient may be infected with this virus. There are many causes of genital warts, the most important of which is unclean sexual behavior. In addition, poor immunity can also easily lead to infection.

1. Sexual Behavior

Most studies have shown that the number of women's sexual partners, the frequency of sexual intercourse, and the presence of genital warts in their sexual partners are closely related to HPV infection. Although some studies have shown that the age of first sexual intercourse is also related to HPV infection, this factor is affected by the number of sexual partners. After adjusting for the number of sexual partners, its risk is not significantly significant.

2. Immune factors

The host's immunity plays a major role in the progression of HPV infection and lesions. Studies have found that the HPV infection rate in immunosuppressed kidney transplant recipients is 17 times that of the normal population. The incidence of HPV infection is also increased in people infected with HIV. The risk of HPV infection increases due to factors such as promiscuous sexual behavior, a large number of partners, and a young age of first sexual intercourse among HIV-infected people. However, some studies cannot prove that immunosuppression is directly correlated with HPV infection. HIV population may have a higher HPV infection rate due to their high risk of exposure or reduced ability of the body to resist latent viruses. The HPV DNA detection level in this population is higher than that in the normal population, indicating that the body's ability to inhibit HPV infection is reduced.

3. Pregnancy

Studies have shown that an increase in the number of pregnancies, births, and abortions in women does not increase the risk of HPV infection, but the number of malformations is related to HPV infection. Some studies have shown that the HPV infection rate is high in pregnant women and the amount of virus detected is also increased, but this may be due to the increase in virus levels during pregnancy, which improves the detection efficiency. A study using the PCR method to detect HPV confirmed this view. The PCR method for detecting HPV virus is independent of the virus content. The results showed that there was no significant difference in the infection rate between pregnant and non-pregnant women (9.6%/10.9%).

4. Oral contraceptives

Although oral contraceptives can increase the risk of cervical cancer, whether they affect HPV infection is still controversial. Studies have shown that oral contraceptives can indeed increase the risk of HPV infection, but some people believe that oral contraceptives have no effect on the occurrence of low-grade cervical lesions, but can increase the risk of high-grade lesions. Therefore, it is believed that oral contraceptives affect the HPV infection rate by changing the progression of the disease rather than directly affecting it.
