skin and mucous Herpes - Causes, Symptoms and Treatment .MF .
There are more than 80 types of herpes viruses.Herpes is sick all life on planet Earth, except for mushrooms and certain types of algae.Of the 80 types of herpes, in humans the disease may cause a herpes virus 9. have specificity, i.e.a person can not get sick with herpes, which affects pigs and pig can be infected by human.An exception is the simian herpes virus.
Approximately 90% of the population are infected with herpes .In 5% of the population of manifestations of herpes and the remaining asymptomatic carriage.Primary infection with herpes simplex virus usually occurs in early childhood, but sometimes later.In most children, symptoms of infection are limited to sporadic eruptions around the mouth.Occasionally develops acute stomatitis with marked changes in the general condition.Herpes can "jump" on the lips and nose, and body, and on the genitals (genital herpes).
causative agent of herpes on the lips, herpes and genital herpes is herpes simplex virus (HSV).
Physico-chemical properties of the herpes virus : die when exposed to temperature, at 500C for 30 minutes.When 37,50C - for 20 hours.It can be stored indefinitely at a temperature of -700C.Well tolerated lyophilization.Resistant to successive freezing and thawing, to the effects of ultrasonic radiation.The saliva in the range of 30 minutes to store the virus retains its viability.In wet sterile medical gauze and wool - during the time of drying (up to 6 hours).The average virus "viable" in the environment under normal temperature and humidity for 24 hours.
The above data refer to the destruction of the virus invitro or laboratory conditions. kill the virus within the body with the help of existing techniques unrealistic (gipertemiya, removing the nerve ganglia, ganglia destruction by introducing into them chemicals, blood ozonation, etc.).Attempts such treatment can lead to profound disability or even a patient's death.
herpes simplex viruses are inactivated by the action: X-ray and ultraviolet ray, alcohol, organic solvents, phenol, formalin, proteolytic enzymes, bile, common disinfectants.
Infection is transmitted mainly by contact (through kissing, a common dish, towel general, during sexual intercourse), as well as airborne, and possible route of infection transplacental (from mother to fetus during delivery).
The virus enters the body through the skin or mucous membranes, then falls to the regional lymph nodes, blood and internal organs.Spread the virus through blood and nerve trunks, the way it is in the nerve ganglia, the virus remains for life, occasionally causing acute at lower immunity, when overheating or overcooling, in stressful situations, a number of diseases (eg. Pneumonia, influenza, malaria and others.), the gastro-intestinal disorders while taking some medications after surgery.
possible damage to the following organs herpes virus:
- eyes (keratitis, conjunctivitis);
- mucous membranes (of the face and genitals);
- central nervous system (meningitis, encephalitis).
Way herpes infection:
sexual, airborne (very rare), with a primary infection of the virus can be transmitted through the placenta.
