What is a Feverblister or Cold Sore (Oral Herpes HSV1)?
Herpes is a common viral infection. It causes Oral Herpes- Cold Sores or Fever Blisters, and Genital herpes - Genital Sores or sores usually below the waist.
These viruses look quite similar under the high magnification of an electron microscope, and generally have an affinity for specific tissues. There are two major types of this virus: Type 1 Herpes or HSV-1 has an affinity for the tissue around the lips, under the nose and eyes, but can infect other tissues as well. In most cases the virus likes tissue on or around the facial lips. Type 2 or HSV-2 has an affinity for the tissue around the genitals.
