The papillomavirus has become widespread.Experts have been able to discover hundreds of its species, each of which causes unique symptoms.It is quite easy to get infected;all you need to do is contact a carrier.To protect yourself from an infectious agent, you need to understand how HPV is transmitted.
Key Features
The human papillomavirus comprises a group of microorganisms that includes 100 subspecies, and 13 of them can cause tumors.These varieties are called oncogenic.HPV is primarily transmitted through sexual contact.Particularly dangerous are types 16 and 18, which in 70% of cases cause cancer.Degeneration in atypical cells is observed in the area of the external genitalia, as well as in the cervix.In some states, a vaccine against oncogenic strains has been approved and is actively used.
After the onset of sexual activity, infection is equally common in both men and women.There are types of HPV that do not cause problems.Sometimes the infection goes away on its own, without outside intervention.This can take several months, but certain types of diseases caused by HPV can take several years to clear up.
HPV types 6 and 11 cause the formation of genital warts.They are quite contagious.HPV has its own DNA, which is helical in shape.Such a microorganism does not have a shell.The virion reaches 55 nanometers in diameter and can be present for a long time on various surfaces, as well as in air and water.Some varieties are oncogenic, that is, they can cause the degeneration of the cellular epithelium into an atypical one.HPV types are designated with special numbers. Those with low oncogenicity are:
- 42;
- 43;
- 44.
Types 16 and 18 are considered dangerous.It is also common to find strain 33, which can cause cancer in women.The accumulation of the infectious agent occurs in the cells of the mucous membranes.
Here the replication of the microorganism is observed, after which persistence occurs in different layers of the epithelium.From this moment the process of transition from cells to atypical cells begins.
Transmission routes
Scientists managed to find out not so long ago 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.Normally, this phenomenon is observed in the presence of microtrauma.This requires contact with an infected person.There is also a route of internal infection, which today raises many questions.
The human papillomavirus has several routes of transmission.Sometimes infection can occur in public places, for example, in swimming pools and baths.It is possible for the infection to enter the mucous membranes when the skin is damaged by shaving, cutting nails, etc.Newborn children become infected when passing through the mother's birth canal.Medical workers who perform surgeries on patients with HPV are at risk.Urological and gynecological examinations are dangerous, but this can be avoided by using gloves and disposable 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 opinion that the causative agent of the disease was transmitted exclusively through sexual contact, after the introduction of the polymerase chain reaction method it became clear that there are many more routes of infection.
It is possible to determine whether papillomas are contagious only after making a correct diagnosis.After entering the human body, the virus passes through the bloodstream and adheres to the epithelium of the genitals, in the anus.It then penetrates the epithelium and its DNA, forcing the cells to function differently.The damaged epidermis grows and divides. The incubation period of HPV does not exceed 3 months., but in some circumstances this period may be shortened or extended to several years.
HPV can remain latent in the body for a long time, sometimes it is present even from birth.The virus can be transmitted from person to person quite easily.Sometimes one can become infected with a pathogenic microorganism through the saliva of a sick person (especially when kissing).Its prevalence today is great.Individual people are carriers and are capable of infecting others.External manifestations of pathology are detected in 1/3 of women of childbearing age during routine examinations.Specialists expect the presence of such a virus in the body 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.It's called HPV.After entering the body, after a while, the cells grow in the form of warts, condylomas and papillomas.Half of sexually active people have encountered this virus.The infection can take a year or more to manifest and sometimes does not cause any symptoms.In most cases, the disease has a relapsing course, and sometimes self-healing is possible.
Among the known urogenital viral infections, PVI is the most widespread.Its clinical manifestations are varied.Of the 100 species known today, 30 lead to the formation of growths in the anogenital zone.Some types of HPV can cause malignant tumors of the cervix and external genitalia in women and men.Transportation can occur when symptoms do not appear.These shapes are discovered by chance during an examination.
The papillomavirus manifests itself anywhere.It can be the skin under the mammary glands, on the neck and armpits.It is active on mucous membranes.Condylomas on the genitals contribute to discomfort and altered aesthetics.Such growths can cause bleeding.
The same prevalence is observed in both sexes.The papillomavirus appears more frequently in people with weak immune systems.Those who abuse alcohol and cigarettes and are promiscuous are at greater risk of infection.
The microorganism is also activated in young people if an unfavorable situation has occurred. An example would be the long-term use of certain medications., gastrointestinal diseases, respiratory viral infections.People who often go to the beach should also be careful, as there is a lot of humidity here.In addition, the skin is almost not covered by clothing.
Infection can occur not only in casual acquaintances, but also in people with whom a healthy person lives.
Characteristic symptoms
Most known types of HPV do not cause painful symptoms.But if this types 16 or 18, precancerous pathologies are possible.These conditions cannot be ignored.The rebirth process can take years, so an infected person always has the opportunity to seek help in a timely manner.By the way, calluses on the feet are also formed with the participation of the papillomavirus.
Throughout life, a person's health changes.Although the immune system is relatively strong, only common warts or harmless juvenile neoplasms are likely to appear.With more serious problems with the body's defenses, papillomas appear on a thin stalk.They are located on the eyelids, under the arms and on the neck.For preventive purposes, experts recommend removing such tumors.
Genital warts are caused by HPV strains 6 and 11. These viruses are transmitted through sexual contact.In men, the damaged areas are the coronary sulcus of the head of the penis and the foreskin. For women it is:
- lips;
- area near the vagina;
- year.
If such growths are left untreated for a long time, the pathology progresses.Women may experience bleeding in the vaginal mucosa after sexual intercourse.You may also experience discomfort, foul-smelling discharge, and pain in your pelvis, legs, or back.Symptoms increase as the infectious agent spreads.
About 80% of women have to deal with viral infections.If we talk about HPV, then its entry into the body is facilitated by the early start of intimate life, sexual relations without using a condom.The number of diseases caused by HPV has increased significantly in recent years.The occurrence of cervical cancer in sexually active girls is explained by the imperfect functioning of the immune system.During this period, the hormonal state does not have time to fully restore itself.
Treatment methods
In women between 20 and 30 years old, human papillomavirus infection can leave the body on its own within a year.This does not even require special treatment, since the immune system copes with the function of getting rid of microorganisms.But correctly chosen treatment tactics remain preferable, regardless of gender and age.This is a 90% successful result.
Each doctor has his own opinion on treatment tactics.But there are fundamentals on which all specialists base themselves.
Therapy must be comprehensive.Typical destructive methods of surgical intervention are not always justified.Doctors often recommend restorative, antiviral and immunomodulatory agents.It is advisable that both partners undergo such treatment.Additionally, to effectively get rid of HPV, you must use condoms.
