Whether you call it a cold sore or a fever blister, oral herpes is a common infection of the mouth area caused by the herpes simplex virus type 1 (HSV-). Between 50 and 80 percent of Americans, cold sores, also called fever blisters, is a common viral infection. They are small, fluid-filled blisters on and around the lips. These blisters are often grouped in patches.
Once the blisters break, a crust forms and can last for several days. Cold sores usually heal in two to three weeks without scarring. Cold sores are small blisters that form on the lips or around the mouth. They are caused by the herpes simplex virus.
Cold sores usually go away without treatment within 10 to 14 days. A cold sore is a fluid-filled blister (or group of blisters) that appears on the lips and around the mouth. If you develop the herpes simplex virus at a young age, it may be triggered from time to time in the future. When the virus is activated or activated, it “wakes up” and travels through the nerves to the lips, where a cold sore develops.
Most people with oral herpes became infected during childhood or when they were young adults through non-sexual contact with infected saliva. The herpes simplex virus can be difficult to diagnose because it can be confused with many other infections, such as allergic reactions. Once you've had an episode of herpes infection, the virus remains latent in nerve cells in the skin and can appear as another cold sore in the same place as before. It can be spread by kissing, touching the infected person's skin, or sharing infected objects, such as lip balm, cutlery, or razors.
The herpes virus is spread through physical contact, such as kissing, sharing a toothbrush, even sharing a drinking glass or through sexual contact. Sometimes, oral and genital herpes viruses can spread, even when there are no sores or blisters in the mouth.
