Herpes simplex virus (HSV) can cause infections that affect the mouth, face , the genitals, the skin, the buttocks, and the anal area. There are two different types of HSV:
•    Type I – Also known as herpes labialis, causes infections mostly as oral “cold sores”. Oral herpes is highly contagious, and is spread by close contact with a person who has herpetic lesions.. HSV can be transmitted to a person regardless of the presence or absence of symptoms, but people are most contagious when they have active blister-like sores.
•    Type II – Occurs mainly bellow the waist leading to the genital herpes. Genital herpes is also highly contagious, and is spread by sexual intercourse with someone who has the virus. Once exposed, symptoms appear within 2 weeks and manifests as an itching or tingling sensation followed by redness of the skin and then blisters.
Both types of these HSVs are extremely contagious and are capable of infecting the skin at any location on the body. No matter where the first outbreak occurs, the cold sore tends to recur in more or less the same place. Recurrences can happen once a month, once a year or only on occasion.
When you first get the infection, the virus enters the nerve cells and travels until it come to a place called ganglion, where it lays dormant. At times, the virus may replicate again and travel down the nerve to the skin, resulting in sores and blisters. It is not clear the exact mechanism behind it, but some conditions seem to be associated with recurrences such as:
•    A fever, cold or the flu
•    Stress
•    Ultraviolet radiation (exposure to the sun)
•    Changes in the immune system
•    Trauma to the skin
•    Sometimes no apparent cause for recurrence
You can treat herpes by taking certain creams or pills that treat the infection. Generic Zovirax comes highly recommended—it’s effective, safe, and affordable.
