Where do cold sores come from?

Answer 1

The root cause of a cold sore is the virus known as the herpes simplex virus. There are eight types of this virus but only two of them are the ones which have been known to answer the question of why do people get cold sores. These types are the herpes simplex type 1 and 2. Why do people get cold sores? People get cold sores when the virus becomes triggered and begins to replicate themselves. They do this replication process commonly on the upper portion of the lip or on the nose. This is basically why people get cold sores. What most do not know about is that stress is the primary reason that causes cold sores to just break out. Most common are illnesses and injuries that cause stress and will in effect cause the virus to wake up. Why do people get cold sores when they have flu or with too much exposure to sunlight? Cold sore viruses tend to replicate in an environment that is warm. If you get yourself too much exposed to heat, chances are, you will get to experience a cold sore. Herpes virus lays dormant on nerves and when triggered by stress, it travels along the nerve to the lips, nose, face and other areas of the body (wherever the initial site of exposure) and one experiences an "outbreak." It is possible to have Herpes Simplex Virus I and II on any area of the body. The usual transmission is by direct contact with a sore from a person who has Herpes. There is evidence that the virus is transmitted by saliva or mucus membranes for several days before the person develops a sore. (The classic example is a kiss from dear old Aunt Hilda or parent, grandparent, etc.) The virus can also live on moist towels for an unknown amount of time. Because it is a virus, it requires living cells to replicate. The tricky part is determining when the virus is no longer viable when in contact with items such as moist towels.
