- Causes of Cold Sores

- QUESTION: I get cold sores about three or four times a year, and that has
- been going on for years. I live in a very cold climate and have always
- associated the outbreak of sores with extra cold weather. However, I was on a
- visit to my brother in Florida, and despite the fine warm weather, had another
- session with these sores. Now I have to rework my thinking about the causes
- of cold sores, unless you would be kind enough to explain their cause to me?
- I would be very much obliged.

- ANSWER: The itchy, crusty rash of the "cold sore" is actually the result of a
- viral infection. It is the herpes simplex virus (HSV) that provokes the
- outbreak of the rash, which may be located any where on the skin or mucosal
- tissues but is most commonly seen around the mouth, on the lips, or on the
- genital organs. There are two types of HSV, labeled HSV-1, usually the cause
- of lip lesions and HSV-2, which produces the rash seen on the genital organs.
- Once the viral infection is in the system, it remains hidden in the body
- between outbreaks inside certain nerve tissues, and can provoke another
- eruption of the rash at times of stress (both physical and emotional),
- overexposure to sunlight, exposure to certain drugs or foods, as well as
- problems in the immune system. Often the trigger mechanism goes undetected.
- In your case it would seem that the excessive cold in your home climate has
- that effect on you.
- However you ran into a more commonly identified reason when you visited a
- warmer climate and were exposed to higher levels of the sun's rays. Recent
- research has demonstrated that individuals who are susceptible to recurrent
- cold sores may be able to prevent outbreaks by using a suntan lotion or cream
- with a protective factor of 15 or higher (SPF 15) when going out into a sunny
- climate.
- There are also medications in both pill and cream form which may help you
- reduce the effects of the sore, and reduce the severity of the outbreak.
- Acyclovir (a prescription medication) can reduce the intensity, and
- antibiotics are useful when a secondary infection complicates the situation.
