Symptoms of HPV18 infection

Many people mistake the HPV virus for the HIV virus when they see it. Yes, these two viruses are completely different viruses, because the HIV virus is highly contagious, and the treatment method is also relatively complicated. However, the HPV virus is a papillomavirus. Although it is contagious to a certain extent, it is not as strong as the HIV virus. There are many types of HPV viruses. What are the symptoms of HPV18 infection?

PV virus is the abbreviation of human papillomavirus, which is a genus of papillomavirus A in the family Papovaviridae. It is a sexually transmitted disease caused by spherical DNA virus infection. The main types are HPV1, 2, 6, 11, 16, 18, 31, 33 and 35. Long-term infection with HPV16 and 18 may be related to cervical cancer in women.

The virus mainly infects the human epidermis and mucosal squamous epithelium. More than 130 species have been isolated so far. The virus only invades humans and is not pathogenic to other animals. After regular systematic treatment, the virus will be eliminated by the human body. Some scholars have also suggested that the virus can be carried for life. This debate still requires scientific research and demonstration.

1. Benign skin manifestations

⑴ Common warts: Papules the size of rice grains, with obvious keratinization on the surface, rough and uneven, thorn-like tips, and hard texture. The lesions may be single or multiple, and may gradually increase by self-inoculation. It often occurs in the hands, feet, etc.

⑵ Disease manifestations in special parts: Periungual warts: occur around the nails and toenails, manifested as thickening and keratinization under the nail. Plantar warts: occur on the soles of the feet, and bleeding spots and black spots can be seen on the surface of the lesions due to pressure. Filiform warts: occur on the neck and eyelids

It is soft and thread-like with multiple tiny warts. Flat warts: They mostly occur on the face and trunk. They are mostly flat papules 2-5mm in size, skin color or light brown, with a smooth surface, and are round or quasi-round. They are occasionally scratched due to itching, forming autoinoculation, or implanted along the surface of skin damage.

⒉ Benign manifestations of external genital diseases ⑴ Genital warts (condyloma acuminatum): include three states: typical manifestations, subclinical infection and latent infection.

(a) Typical manifestations: Typical skin lesions visible to the naked eye: papilloma-like, cauliflower-like, granular, cockscomb-like, etc.

(b) Subclinical manifestations are difficult to identify with the naked eye and can only be observed with the help of a magnifying glass or acetowhite test. Histological and cytological tests show typical HPV pathological changes;

(c) Latent infection is when HPV enters the cells of the skin and mucous membranes and does not cause any clinical manifestations or histological abnormalities, but can be detected in the cells of the skin and mucous membranes through molecular biological methods, nucleic acid hybridization, etc. Prone areas: Female vulva, vagina, cervix, around the anus, inside the anal canal, and urethral opening; male vulva, penis, testicular surface, urethral opening, around the anus, inside the anal canal, etc.

Rare locations: armpits, navel, between toes, under breasts, etc.

⑵Special areas: wart-like lesions on the surface of oral mucosa, recurrent respiratory papillomatosis, etc.

HPV infection routes

⒈ Sexual transmission;

⒉ Close contact;

⒊ Indirect contact: through contact with the infected person's clothing, daily necessities, utensils, etc.; ⒋ Nosocomial infection: medical staff do not provide good protection during treatment and care, causing self-infection or transmitting the virus to patients through medical staff; ⒌ Mother-to-child transmission: close contact between the baby and the pregnant woman through the birth canal.
