Papillomavirus is widespread.Experts have been able to discover hundreds of species, each of which causes unique symptoms.It is quite easy to get infected - you only need to contact a carrier.To protect yourself from an infectious agent, you need to understand how HPV is transmitted.
Key Features
Human papillomavirus consists of a group of microorganisms with 100 subtypes, 13 of which can cause tumors.Such species are called oncogenes.HPV is mainly transmitted through sexual contact.Especially dangerous are types 16 and 18, which cause cancer in 70% of cases.Degeneration into atypical cells is observed in the external genitalia, as well as in the cervix.A vaccine against oncogenic strains has been approved and is actively being used in some states.
Infection after sexual activity is equally common in both men and women.There are types of HPV that do not cause problems.Sometimes the infection disappears on its own without any external intervention.This can take up to a few months, but some diseases caused by HPV can take several years to clear up.
HPV types 6 and 11 cause genital warts.They are highly contagious.HPV has its own DNA, which is a helical shape.Such a microorganism does not have a shell.The diameter of the virion reaches 55 nanometers and can remain on various surfaces for a long time, as well as in air and water.Some types are oncogenic, that is, they can cause an atypical degeneration of the cell epithelium.HPV types are designated by special numbers. Low oncogenicity is the following:
- 42;
- 43;
- 44.
Types 16 and 18 are considered dangerous.Strain 33, which can cause cancer in women, is also commonly found.Accumulation of the infectious agent occurs in the cells of the mucous membranes.
Here, the replication of the microorganism is observed, after which continuity occurs in different layers of the epithelium.From this moment, the process of cells transitioning into atypical cells begins.
Transmission routes
Some time ago, scientists were able to find out exactly how the human papillomavirus is transmitted in women and men.It penetrates the epithelium only after direct contact with the skin or mucous membranes.Typically, this phenomenon is observed in the presence of microtrauma.This requires contact with an infected person.There is also an internal route of infection, which raises many questions today.
Human papillomavirus has several ways of transmission.Sometimes the infection can occur in public places, such as swimming pools and baths.Shaving, nail trimming, etc.when the skin is damaged, it is possible for the infection to pass to the mucous membranes. Newborn children are infected while passing through the mother's birth canal.Healthcare workers who perform surgery on HPV patients are at risk.Urological and gynecological examinations are dangerous, but this can be avoided by using disposable gloves and medical instruments.
People who work with raw fish and meat can also become infected.There is even a special concept - "butcher's warts".And if earlier there was an idea that the causative agent of the disease was transmitted only through sexual contact, after the application of the polymerase chain reaction method, it became clear that there are more ways of infection.
It is possible to determine whether papillomas are contagious or not only after a correct diagnosis.After the virus enters the human body, it passes through the bloodstream and attaches to the epithelium of the genitals and the anus.It then penetrates the epithelium and its DNA, forcing the cells to act differently.Damaged epidermis grows and splits. The incubation period for HPV is no more than 3 months, but in some cases this period can be shortened or extended up to several years.
HPV can remain hidden in the body for a long time, sometimes even present from birth.The virus can be transmitted from person to person very easily.Sometimes you can get infected with a pathogenic microorganism through the saliva of a sick person (especially during kissing).Today, its spread is huge.Individuals are carriers and can infect others.External manifestations of pathology are detected during regular examinations in 1/3 of women of reproductive age.The presence of such a virus in the body is expected by experts more than its absence.
PVI and its characteristics
Human papillomavirus infection is a disease caused by an infectious agent present in the skin and mucous membranes.This is called HPV.After some time after entering the body, the cells grow in the form of warts, condylomas and papillomas.Half of the people who have sex have encountered this virus.The infection can take a year or more to manifest itself and sometimes causes no symptoms.In most cases, the disease has a recurring course, sometimes self-treatment is possible.
Among known urogenital viral infections, PVI is the most common.Its clinical manifestations are different.Of the 100 species known today, 30 cause growths in the anogenital area.Some types of HPV can cause malignant tumors of the cervix and external genitalia in women and men.Carriage can occur when no symptoms appear.These forms are discovered accidentally during the exam.
Papilloma virus manifests itself everywhere.This can be the skin under the mammary glands, neck and armpits.Active on mucous membranes.Genital warts contribute to discomfort and aesthetic disturbance.Such growths can cause bleeding.
The same prevalence is observed in both sexes.Papillomavirus is more common in people with weakened immune systems.People who abuse alcohol and cigarettes and who are promiscuous are at higher risk of infection.
The microorganism is also activated in young people when any unfavorable situation arises. For example, there may be long-term use of certain drugs., gastrointestinal diseases, respiratory viral infections.People who often go to the beach should also be careful, because there is high humidity here.In addition, the skin is almost not covered by clothes.
Infection can occur not only from casual acquaintances, but also from people with whom a healthy person lives.
Characteristic symptoms
The most common types of HPV do not cause painful symptoms.But if this type 16 or 18, precancerous pathologies are possible.Such conditions cannot be ignored.The process of rebirth can take years, so an infected person always has the opportunity to seek help in time.By the way, calluses on the legs are also caused by the papilloma virus.
A person's health changes throughout life.Although the immune system is relatively strong, only ordinary warts or harmless juvenile neoplasms can occur.With more serious problems with the body's defenses, papillomas appear in a thin thread.They are localized on the eyelids, under the arms and on the neck.For the purpose of prevention, experts advise to remove such tumors.
Genital warts are caused by HPV 6 and 11 strains.These viruses are transmitted through sexual contact.In men, the affected areas are the coronary groove of the head of the penis and the foreskin. For women, this is:
- labia;
- the area near the vagina;
- the anus.
If such growths are not treated for a long time, the pathology progresses.Women may have vaginal bleeding after intercourse.You may also experience discomfort, foul-smelling discharge, pelvic, leg, or back pain.Symptoms increase as the infectious agent spreads.
About 80% of women experience viral infections.If we are talking about HPV, then its entry into the body is facilitated by early initiation of intimate life, sexual intercourse without condoms.In recent years, the number of diseases caused by HPV has increased significantly.The occurrence of cervical cancer in sexually active young girls is explained by the imperfect functioning of the immune system.During this period, the hormonal situation does not have time to fully establish itself.
Treatment methods
In women aged 20-30, human papillomavirus infection can leave the body on its own after a year.It does not even require special treatment, because the immune system copes with the function of getting rid of microorganisms.However, regardless of gender and age, the right treatment tactics are preferred.This is a 90% success rate.
Each doctor has his own opinion on treatment tactics.But there are basics that all experts rely on.
Therapy should be comprehensive.The destructive methods characteristic of surgical intervention are not always justified.Doctors usually recommend restorative, antiviral and immunomodulatory drugs.It is recommended that both partners undergo such treatment.Also, you should use condoms to effectively get rid of HPV.
