How harmful is human papillomavirus?

Human papillomavirus is a genetic epidemic that is still very common. The patient's condition is contagious and has a wide range of transmission routes, including sexual contact, genital secretions, mother-to-child, oral, etc. It is mainly transmitted between blood and blood, and secretions. Patients with papillomavirus must take precautions.

1. Epidemic characteristics The epidemiology of HPV infection is still not fully understood. There is a lack of extensive serological epidemiological survey data. According to the currently known epidemiological data, it is clear that several types of HPV infections are common in the population, mainly causing a variety of skin and mucosal surface infections. This infection has age differences but no gender differences. The most common is common skin warts, accounting for 50% of the total HPV infection, and occurs more frequently in children. Genital warts, also known as genital warts, are a sexually transmitted disease. Since 2000, the incidence rate has increased significantly in the United Kingdom and the United States. A study completed in the United States in 2002 showed that the detection rate of HPV DNA in female STD clinic patients reached 49.2%.

2. Source of infection: Patients with clinical and subclinical infection are the main source of infection. Latently infected people (carriers) are not only reservoir hosts of HPV, but can also serve as sources of infection.

3. Transmission routes HPV is mainly transmitted through direct or indirect contact with objects contaminated with HPV.

(1) Direct contact is the main route of transmission, such as sexual contact. The risk of infection from genital warts in one sexual intercourse is estimated to be 50% to 60%. The disease is most contagious within 3 months

(2) Indirect (non-sexual) contact transmission of papillomavirus, through contaminants containing the virus (underwear, bathtubs, toilets, towels, etc.), or through non-sexual contact in the home, and skin and mucous membrane damage is an important predisposing factor.

(3) Mother-to-child transmission: HPV infection in the mother is transmitted to the baby through the birth canal during delivery, or through close contact during postpartum health searches.

(4) Self-inoculation and spread to other parts of the body.
