Fever Blister Information - Fever Blisters & Cold Sores. Cold sores, also known as fever blisters or herpes labialis, are recurrent infections caused by the herpes simplex virus. See the Colgate online article about cold sores and fever blisters to learn what causes fever blisters as well as cold sores and other types of viruses. Fever blister: A small sore situated on the face or in the mouth that causes pain, burning, or itching before bursting and crusting over.
Herpes Simplex also known as cold sores or fever blisters, are painful lesions which usually form on the lips, chin, cheeks, or nostrils. The blisters typically turn into yellow-crusted sores and then disappear within a couple of weeks. Unfortunately, people who get cold sores, which are caused by the herpes simplex virus (usually type 1), generally get outbreaks over and over again, and they are highly contagious. While there is no cure or vaccine at this time, there are things you can do to ease the pain of cold sores, speed up their healing, and stop their spread.They hurt really bad if you dont take care of them.But you need to get the right rub for them to heal.
What Are the Causes of Fever Blisters? Fever blisters are one of the most common conditions of the mouth. Also known as cold sores (and known medically as herpes labialis), fever blisters are caused by a contagious virus called the herpes simplex virus.
There are two types of herpes simplex viruses:
Herpes simplex type 1 (HSV-1)
Herpes simplex type 2 (HSV-2)
Most cases of fever blisters are caused by HSV-1. In fact, more than 95 percent of recurrent fever blister outbreaks are caused by HSV-1. Most people infected with the HSV-1 virus usually become infected before they are 10 years old.
Fever Blisters Proven Fever Blister Treatment - A fever blister is a fluid-filled, painful blister which usually occurs on or around the lips. Fever blisters are also known as fever blisters, oral herpes, herpes febrilis, labial herpes and herpes labialis. Fever blisters most often occur on the external lips which distinguishes them from the common canker sore which is usually found inside the mouth.
Fever blisters are caused by the herpes virus. There are some eight different types of human herpes viruses. However, only two of these viruses, herpes simplex, types 1 and 2, cause fever blisters. Common belief is that herpes simplex virus type 1 infects above the waist and herpes simplex virus type 2 infects below the waist. However, this is not always the case both herpes virus type 1 and type 2 can cause herpes lesions on the lips or genitals. However, recurrent fever blisters are almost always a result of the herpes virus type 1.
Unfortunately, oral herpes is very common. Some 80% of the population has had a fever blister while almost 25% of those infected will experience recurrent outbreaks. Individuals can become infected by herpes virus and the virus may remain latent for life or the virus may promote frequent recurrent fever blisters. The highest risk for spreading the virus is the time period beginning with the appearance of the ulcers or blisters. However, infected individuals do not need not have visible ulcers to spread the infection. In addition, the virus may be present in the saliva of infected individuals without obvious oral lesions. Viruses are not the same as bacteria. Bacteria are independent cells and can reproduce without the assistance from their host. While, viruses enter their host cells and use the host to replicate the virus. The infected host cell is subsequently killed while the virus is released. For example, in the case of fever blisters the actual ulcer is formed from the death of the cells and the immune response against the virus. The virus can also remain dormant for weeks or even years until some event triggers the virus to become active.
