- Genital herpes: eliminate sex
- Repeated herpes
Herpes infection was known to the ancient physicians, including genital herpes was known. The causes of this disease become known only at the beginning of the last century, when it was proven viral nature. After the invention of the last century in the middle of an electron microscope herpes viruses have been studied. Today, there are eight types of herpes viruses that cause disease in humans. Another type gerepesa virus can be transmitted from person to monkeys.
Reasons - herpes simplex virus first and second types
Of the nine herpes viruses that cause disease in humans, only two can cause genital herpes. This herpes simplex viruses of the first and second type - HSV - 1 and HSV - 2 mainly a disease caused by HSV-2, HSV-1, but also it may cause in recent years is the number of infections of HSV-1 increases, which may due to the increase in the number of oral-genital sex. Usually, however, HSV-1 causes cold sores on the lips, so-called "cold."
What are HSV-1 and HSV-2
Herpes simplex viruses
Herpes simplex - in fact, not so simple
first and second types differ slightly only in the structure of two surface proteins. This DNA-containing viruses that have a body covered with the outer and inner shells, as well as the capsid inside which is a DNA consisting of the 80 genes, were divided into three types.
Genes involved in the penetration of the virus in epithelial cells in primary infection and recurrence of the disease, is the matrix for the construction of new DNA viruses that contribute to shutdown function of the host cell nucleus and the synthesis of substances necessary for the interaction and attachment to the new cells. Inside the virus also contains enzymes.
Herpes viruses are not afraid of the cold, drying and exposure to ultraviolet rays, but at 50 ° C they die within half an hour. Especially long the virus retains its ability to live on damp surfaces.
In humans, HSV-1 and HSV-2 are preserved forever. Their main "home" is the nerve plexus of the lumbosacral region, where the virus is in an inactive state. But under certain conditions it can get out of the nerve plexus, move along nerve fibers to the mucous membranes and cause disease.
As transmitted HSV-1 and HSV-2
These viruses are transmitted mainly through sexual contact under normal heterosexual intercourse (mainly HSV-2) and oral-genital contact (HSV-2). It is not excluded and household transmission of herpes viruses
Herpes - a virus creeping
But it is more typical for children in close household contact with parents, including using a towel, toothbrush
Toothbrushes - make no mistake in choosing
and so on.
What happens in the body in contact with the herpes virus
The herpes virus after contact with genital mucosa may be a certain time (the incubation period - for genital herpes it is from one to ten days) of causing disease or the time to hide in the nerve plexus. It all depends on the state of immunity
Immunity - types and characteristics in children in adults
The disease begins with the fact that the herpes virus first attaches to the surface of epithelial cells of the genital organs, and then enters the cell membrane resets and enters the nucleus of the cell where new viruses are played, then leaves the cell and injects located next to healthy cells. When a sufficient number of viruses, symptoms of the disease.
But if a person has a good immune system, it does not allow viruses to penetrate into the cells of the epithelium. In this case, the viruses are moving along the nerve fibers in the nerve ganglia, located in the lumbar region and there "freeze" in an inactive state. That is why most people are unaware that they are carriers of viruses.
Once human immunity decreases (this occurs when exposed to certain factors), the virus in the same way leaves the nerve ganglia to the surface of mucosal epithelial cells to attach, to multiply and cause disease.
Predisposing factors for the development of the symptoms of herpes
Contributing factors for the development of the disease are any effects on the body, resulting in reduced immunity. It may be cold, any acute illness, frequent exacerbation of chronic diseases, physical and psychological overload, severe stress, trauma, surgery and so on. Contributing factors may be infected by other sexually transmitted diseases.
Genital herpes - a chronic viral infection, a sexually transmitted. Genital herpes is very contagious, avoid infection through sexual contact is very difficult, it does not help even a condom. The only reliable way to prevent the disease - it is sex with only one sexual partner tested.
