Skin sputum is generally benign, HPV DNA is free, and some sputum can resolve on its own. High-risk human papillomavirus is closely related to genital precancerous lesions and malignant tumors. HPV DNA is often integrated into the chromosomes of host cells. The damage caused by HPV is affected by immune factors, and cell-mediated immunity is more important. Skin imperfections occur after HPV infection, and will resolve spontaneously after a long period of time; the incidence of cervical cancer in immunosuppressed patients will increase. basic knowledge The proportion of illness: 0.04% Susceptible people: teenagers Mode of transmission: contact transmission, mother-to-child transmission Complications: malignant tumor
Cause
Skin sputum
Modern medicine believes that cockroaches are caused by viruses, and common warts and ticks are caused by human papillomavirus; infectious soft mites are caused by infectious soft prions. Mainly through direct contact infection.
Common cockroaches and cockroaches are not contagious, but trauma can easily cause prion infection. Infectious soft palate is highly contagious and can be vaccinated by itself.

The flat warts are moved by the liver fire, and the complex heat is poisonous and evil, which is caused by the skin.

After HPV-16, type 18 infection, if the treatment is not timely, 5% to 10% of vulva, cervix, and perianal genital warts may develop cancer after a long period of time, which may cause malignant tumors such as penile cancer and cervical cancer in the future.
4, transmission to the baby, affecting the quality of reproduction. Pregnant women with sputum, during childbirth, can be infected through the birth canal, causing HPV infection in infants and young children.
