Can the incubation period of HPV be detected?

HPV is a contagious disease that is usually transmitted through saliva, blood, and sexual intercourse. After being infected with HPV, the genitals will be prone to itching or rashes, which can cause great harm to the health of the body. It is also highly contagious. There are no symptoms during the HPV incubation period, and it can only be detected through experiments.

Can the HPV incubation period be detected?

The incubation period refers to the period from infection with a pathogen to the onset of clinical symptoms of an infectious disease. During the incubation period, although there are no obvious clinical symptoms, laboratory tests only show positive findings.

Epidemiology

The infection rate of skin-type HPV is very common in the population, such as the common common warts, toe warts, flat warts, etc. The specific infection rate cannot be obtained. What attracts more attention is the genital warts and cervical cancer caused by high-risk HPV infection and low-risk HPV infection of the external genitalia. According to statistics, among sexually transmitted diseases in the world, genital warts caused by HPV infection account for 15-20%.

Regarding the prevalence of HPV infection in the female reproductive tract, according to a survey from the National Health and Nutrition Research Project in the United States in 2003-2004, the overall HPV infection rate for those aged 14-59 was 26.8%, so the burden of HPV infection on women exceeds previous estimates. There have been no large-sample reports on epidemiological screening for HPV infection in my country, but the incidence of genital warts among sexually transmitted diseases caused by HPV infection is increasing rapidly. It is estimated that the incidence rate should be the highest among sexually transmitted diseases because of a large number of underreporting and non-reporting. There are about 131,500 new cases of cervical cancer in my country every year. The incidence and mortality rates reported are on the rise, and the age of cervical cancer patients is getting younger. It is foreseeable that the huge losses caused by HPV infection in my country will be huge.

Infection route

1. Sexual transmission;

2. Close contact;

3. Indirect contact: through contact with the infected person's clothing, daily necessities, utensils, etc.;

4. Nosocomial infection: Medical staff fail to provide adequate protection during treatment and care, resulting in self-infection or transmission of the infection to patients through medical staff;

5. Mother-to-child transmission: It is transmitted through close contact between the baby and the pregnant woman’s birth canal.

Clinical manifestations

Low-risk HPV infection

1. Benign skin manifestations

(1) 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 in number through self-inoculation. Mostly occurs in the hands, feet, etc.

(2) Diseases manifesting in special parts of the body:

Periungual warts: occur around the fingernails and toenails, and are characterized by 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: multiple, soft, thread-like warts that occur on the neck and eyelids

Flat warts: They mostly occur on the face and are also common on the 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.
