To avoid
unpleasant consequences it is useful to know what causes cold sores. Frankly
speaking it is enough to say three words to answer the question what causes
cold sore. These words are "virus herpes simplex". Maybe you heard
that there are two types of this virus. A lot of people know that herpes
simplex 2 is the cause of common sexual disease, and herpes simplex 1 is the
cause of cold sore. This virus is very foxy. It may live in the body of each
person and "sleep" for years and show evidences of its presence. The
statistics says that about 80% of people who live in North
America are carrier of herpes virus (first type). So you
see that this disease is extremely common and even if you or somebody from your
surrounding has this condition it is not the reason to be frustrated.
Generally
the herpes simplex 1 in its inactive state lives in the nerve cells of the
individual's body. A lot of people may have this virus inside but never see its
manifestations on the surface (for example on lips). As a rule it is not very
hard for our immune systems to cope with this virus and defend us from it. But
sometimes when the immune system is very weak or due to some other triggers
this insidious virus may travel to the surface of the body and show everybody
its features. At the time when the virus spreads down the nerve cells it
frequently increases its quantity. This "trip" of the virus from
inside to the surface is usually accompanied by tingling and subsequent
clusters of blisters. In most cases it is located on the individual's lips.
In
learning what causes cold sores it is helpful to know some specific triggers
that may cause "waking up" of dormant herpes 1 virus. Among these
causes it is possible to distinguish the next items: cold weather (have you
noticed that the greater part of people who suffer from herpes you may see on
the streets in winter?); fatigue; fever which may be caused by any infection;
menstrual periods; stress (both mental and physical); physical irritation of
the lips (this may happen after the visit to the dentist); sunlight and
sunburn.
Answering
the question what causes cold sores I cannot help not to say about that cause
which may lead to the occurring herpes on your body even if you do not have it
inside. I am talking about the direct contact with the affected person
(touching the area where you may see herpes evidences, using the same towel,
cup of lipstick with the person who has this disease). This virus can be
transmitted even through handshaking in the case if the affected person touches
herpes blisters and then without washing them touch your hands. But when the
blisters are crusted over you may shake hands with no danger – this person is
not contagious any more.
How to prevent cold sores
There are two main advices how to prevent cold sores. The first is to avoid
contacts with infected body fluids. It means that it is extremely useful not to
kiss your beloved when he or she has herpes on the surface. The second advice
is to avoid using together with the sufferer the same spoon and knives, cups
and towels, lipsticks and other item which the person who is the carrier of the
virus may use.
