Herpes is a viral disease, accompanied by a characteristic rash on the mucous membranes and skin of the blisters with fluid.
Herpes is most often called an infection that is caused by the herpes simplex virus type 1 and type 2.
In everyday life, herpes can also be called "cold on the lips" and also "fever".
Herpes simplex virus usually affects first of all mucous membranes, skin, nervous system, and other internal organs of a person.
According to multiple data from the world's epidemiological studies, herpes is spread all over the globe. Approximately 40 years of age, over 90% of the population already have developed antibodies to the herpes virus, respectively, at least once in their lifetime they have already transferred the infection. The severity of the course of the disease, the susceptibility of the body to herpes infection depend to a large extent on the state of the human immune system.
Herpes virus infections occupy a special place among all infectious diseases.
It's about viruses that provoke various diseases. A common feature of these diseases is the appearance on the skin or on mucous bubble rashes.
Among them: chicken pox, herpes on the lip, shingles, infectious mononucleosis, viral exanthema, genital herpes, etc.
Often physicians emphasize that most often the recurrence of herpes appears after stress, physical activity, operations, also the disease with herpes is a companion of other viral diseases, for example, influenza, ARVI.
The source of infection with herpes is the carriers of the virus, which secrete it into the environment, as well as patients with fresh herpetic eruptions. To infect with herpesvirus infection, it is sufficient to get viral particles on the mucous membranes or on the human skin.
It is also possible and congenital herpes is a viral disease caused by intrauterine infection of the fetus. Intrauterine infection is possible in the case when the mother during pregnancy develops a primary herpetic infection with the corresponding ingestion of herpes viruses into the blood.
Symptoms of herpes
Symptoms of herpes are known to most of the adult population of the planet, but in recent years the number of infected and sick people is constantly increasing.
Symptoms of herpetic infection depend on the severity, extent and localization of the lesion.
The first manifestations of herpes occur 2-7 days after infection or after exposure to a factor that provokes the activation of the virus in the human body. As a rule, such a factor is a disease, stress or hypothermia.
Each of the eight types of viruses causes diseases that have a certain symptomatology.
At 1 type of herpes rashes on the skin most often appear in the form of small single or multiple vesicles. Typically, the first type of herpes occurs on the skin of the face, often the lips.
At type 2 the problem takes place on the skin and mucous in the genital area. With chickenpox, the vesicles are located throughout the body. On the contrary, with herpes zoster, multiple vesicles will be arranged grouped. Herpes virus infection in particular, like the flu, is dangerous for its complications.
Viruses 1 and 2 type affect the skin and mucous membranes of the nose, lips, mouth and external genitalia.
Also, herpes viruses of these types affect the eyes, affecting virtually all anatomical parts of the organ of vision, ENT organs and esophagus.
At the same time, such diseases as stomatitis, keratitis, uveitis, pharyngitis, esophagitis, etc. develop. Sometimes the central nervous system is affected with the development of herpetic meningitis and / or encephalitis.
Type 3 virus (varicella zoster virus) - in children causes chickenpox, and in adults, shingles. When chickenpox rashes single, located on the scalp and throughout the body. The temperature is extremely rare. A feature of rashes with shingles is their location in the places of location of nerves and nerve nodes. A typical location is on the trunk, along the intercostal nerves.Herpesvirus type 4 (Epstein-Barr) causes infectious mononucleosis, which is characterized by the development of angina, hepatitis and lymphadenopathy. The severity of clinical manifestations depends on the state of the immune system. When the deficit of immunity is expressed, severe hepatitis with severe intoxication and jaundice develops.
Type 5 virus (cytomegalovirus) in adults affects the internal organs - the liver, lungs, heart, kidneys. Hepatitis has features similar to hepatitis caused by HHV-4. Pneumonia has the character of necrotic bronchopneumonia and is clinically similar to ordinary bacterial pneumonia, which causes difficulties in diagnosis and treatment. The greatest danger to this type of virus is for the fetus and the newborn.
Herpes virus type 6 is considered guilty of the occurrence of malignant tumors and sudden exanthema in children.
Herpes virus type 7 provokes the development of chronic fatigue syndrome.
And finally, type 8 - causes Kaposi's sarcoma in people with AIDS.
A common symptom of all types of herpetic infection is leukopenia (lowering of blood leukocyte count), which can be detected in the usual general blood test. To confirm the diagnosis, it is necessary to carry out virological (virus detection)
