Herpes simplex causes eruptions on the skin or mucous membranes.
This eruption will disappear, although the virus remains in the inactive state in the ganglia (nerve cell body), which supplies the sense of the infected area.
Herpes simplex infection characterized by recurrent episodes of small blisters on the skin or mucous membranes, which contain fluid and feel tender.
Periodically, the virus will be active again and began to multiply, often causing skin eruption of blisters on the same location as the previous infection.
The virus can also be found in the skin without causing blisters real, in this situation is a source of infection the virus to others.
The emergence of an eruption can be triggered by:
- Sun exposure
- Fever
- Physical or emotional stress
- Immune system suppression
- Medicines or certain foods.
Herpes simplex is marked by a recurrence of numbness, discomfort or itching, which felt a few hours to 2-3 days before the onset of blisters.
Blisters surrounded by red areas may appear anywhere on the skin or mucous membranes, but most often found in and around the mouth, lips and genitals.
Blisters (which can be painful) tend to form groups, which begabung each other to form a larger collection.
There are 2 types of herpes simplex virus that infects the skin, the HSV-1 and HSV-2.
HSV-1 is the cause of the wound in the lips (herpes labialis), and the wound in the cornea (herpes simplex keratitis); usually spread through contact with secretions from or around the mouth.
HSV-2 usually causes genital herpes and is transmitted primarily through direct contact with the wound during sexual intercourse.
