Viral protection

How herpes appears, knows almost everything. In cold
appearance of the characteristic rash around the mouth - a phenomenon
common. Rash is a point bubbles that
then be opened with the formation of painful ulcers. Sores dry up and
approximately two weeks to heal. If damaged in place
skin rash will get the bacteria and develop secondary purulent
inflammation, healing will occur more slowly and can remain
scars.

The most common rash of herpes simplex appears on the skin and mucous
membranes around the mouth (the so-called labial herpes. Next on
frequency space rash - it is sexual organs (in this case herpes
called genital). Much less rashes appear on the hands,
feet and torso. In some cases, herpes infects the eye
(herpetic keratitis) or central nervous system (herpetic
encephalitis).

Herpes simplex can cause two types of virus - HSV-1 and HSV-2. They
transmitted by contact - a liquid which is secreted from the eruption,
contains a large number of viral particles. When the fluid gets
on the skin or mucous membranes of healthy people (for example,
touching, kissing, sexual intercourse, etc.), the virus penetrates
sensory nerve endings and is embedded in the genetic apparatus
nerve cells. Then remove the virus from the body is impossible, he
remain with a person for life. This supports one or
both types of HSV are more than 90% of adults.

However, the rash may not appear at all infected. This is because
that the immune system responds to viral invasion of "inclusion"
specific and nonspecific immunity. In addition, it is connected with
features of the life cycle of the virus.

Specific immunity is the production of antibodies that
selectively attack the appropriate type of virus.

One of the major components of non-specific antiviral
immunity is the production of interferon alpha, beta and gamma - protective
molecules by the cells of an organism in response to the invasion
viruses. Interferons modify the processes of cell activity such
way that it becomes immune to the virus and is not involved in its
reproduction, as well as activate immune cells - lymphocytes and macrophages.

For most people the virus is always in a dormant state, not
causing a rash. But about one-third of infected under the influence of such launchers
factors as stress, hypothermia, concomitant infection, menstruation,
trauma, surgery, radiation and the effect of ultraviolet and
others, the virus "wakes up" and begins to multiply in the nerve cells.
This is manifested in the appearance of the characteristic bubbles locations
nerve endings and release of these large number of viral
particles.

In order for acute herpes were faster course of disease
was easier, and the number of rash - minimum, apply
drugs called adjuvants.
