The papillomavirus has spread.Experts have managed to discover hundreds of its species, each of which causes unique symptoms.It's very 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, 13 of which can cause tumors.These varieties are called oncogenic.HPV is transmitted mainly through sexual contact.Particularly dangerous are types 16 and 18, which in 70% of cases cause cancer.Degeneration into atypical cells is observed in the external genitalia area as well as the cervix.In some states, a vaccine against oncogenic strains has been approved and is being actively used.
After sexual activity begins, infection is equally common in men and women.There are types of HPV that do not cause problems.Sometimes the infection goes away on its own without any outside intervention.This may take several months, but certain types of diseases caused by HPV may take several years to resolve.
HPV types 6 and 11 cause the formation of genital warts.They are quite contagious.HPV has its own DNA, which has a helical shape.This 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 atypical ones.HPV types are designated by special numbers. Low oncogenicity are:
- 42;
- 43;
- 44.
Types 16 and 18 are considered dangerous.Strain 33 is also frequently found, which can cause cancer in women.The accumulation of the infectious agent occurs in mucosal cells.
Here the replication of the microorganism is observed, after which persistence occurs in different layers of the epithelium.From this moment on, the process of transition of cells into atypical cells begins.
Transmission routes
Scientists managed to find out exactly how the human papillomavirus is transmitted in women and men not so long ago.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 a domestic route of 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 bathhouses.It is possible for the infection to enter the mucous membranes when the skin is damaged during shaving, cutting nails, etc.Newborns become infected as they pass through their mother's birth canal.At risk are medical professionals who perform surgeries on patients with HPV.Urological and gynecological exams are dangerous, but 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 it was believed 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 only possible to determine whether papillomas are contagious after a correct diagnosis.After entering the human body, the virus passes through the bloodstream and attaches to the epithelium of the genital organs, in the anus.It then penetrates the epithelium and its DNA, forcing cells to function differently.The damaged epidermis grows and divides. The incubation period for HPV is no more than 3 months, but in some circumstances this period may be reduced or extended to several years.
HPV can remain latent in the body for a long time, sometimes it is present from birth.The virus can be transmitted from person to person quite easily.Sometimes you can become infected with a pathogenic microorganism through the saliva of a sick person (especially through kissing).Its prevalence today is great.Individual people are carriers and are capable of infecting others.External manifestations of the pathology are detected in 1/3 of women of childbearing age during routine examinations.The presence of this virus in the body is more expected by experts than its absence.
PVI and its features
Human papillomavirus infection is a disease caused by an infectious agent present on the skin and mucous membranes.It's called HPV.After entering the body, after some time, 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, a recurrent course of the disease occurs, sometimes self-healing is possible.
Among 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 protuberances in the anogenital region.Some types of HPV can cause malignant tumors of the cervix and external genitalia in women and men.Carriage may occur when no symptoms appear.These forms are discovered by chance during an examination.
The papilloma virus manifests itself anywhere.It could be the skin under the mammary glands, on the neck and in the armpits.It is active on mucous membranes.Condylomas on the genitals contribute to discomfort and aesthetic disturbance.Such growths can cause bleeding.
The same prevalence is observed in both sexes.The papilloma virus appears most often 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 any unfavorable situation occurs. An example would be the prolonged use of certain medications., gastrointestinal diseases, respiratory viral infections.Those who go to the beach frequently also need to be careful, as the humidity is high here.Furthermore, the skin is barely covered by clothes.
Infection can occur not only in casual acquaintances, but also in people with whom a healthy person lives.
Characteristic symptoms
The most well-known types of HPV do not cause painful symptoms.But if this types 16 or 18, precancerous pathologies are possible.Such 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 papilloma virus.
Throughout life, a person's health changes.Although the immune system is relatively strong, only common warts or harmless juvenile neoplasms are likely to occur.With more serious problems with the body's defense, papillomas appear on a thin stalk.They are located on the eyelids, under the arms and on the neck.For prevention purposes, experts recommend removing these tumors.
Genital warts are caused by HPV 6 and 11 strains. These viruses are transmitted through sexual contact.In men, the damaged areas are the coronal groove of the head of the penis and the foreskin. For women it is:
- lips;
- area close to the vagina;
- anus.
If these growths are not treated 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.
Around 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 onset of intimate life, sexual intercourse 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 young girls is explained by the imperfect functioning of the immune system.During this period, the hormonal status does not have time to fully establish itself.
Treatment methods
In women between the ages of 20 and 30, human papillomavirus infection can leave the body on its own after a year.This does not even require special treatment, as the immune system fulfills the function of getting rid of microorganisms.But correctly chosen treatment tactics are still preferable, regardless of gender and age.This is a 90% success rate.
Each doctor has his own opinion on treatment tactics.But there are fundamentals that all experts trust.
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 this treatment.Furthermore, to effectively get rid of HPV, you must use condoms.
