Most Common Causes of Cold Sores
Cold sores are usually caused by herpes virus, which can lay dormant in the body and becomes active later when something triggers it. Cold sores may appear after colds, fevers, exposure to the sun, stress, during menstruation, or for no apparent reason. Generally it is felt that anything that compromises the immune system may trigger the cold sores, such as infection, cancer or any illness.
Many people can generally feel a cold sore coming on as they are aware of a tingling, burning or itching sensation. They may also have a fever, enlargement of lymph nodes close to the sores, or a general feeling of malaise.
Cold sores are caused by a virus, the herpes simplex virus or HSV. There are two kinds of herpes simplex virus, called type 1 and type 2. While both types can cause cold sores, type 1 is the variety usually responsible. Type 2 HSV is found in genital herpes and is much rarer than type 1 HSV.
HSV-1 is the most common cause of cold sores. Most people are exposed to HSV-1 between the ages of three to five. There are many ways that a person can become infected by HSV-1, including among them coming into close contact with a person who has a cold sore, ingesting contaminated fluids that have been sneezed or coughed into the air, or by coming into contact with objects that a person with a cold sore touched or used. Although most people are first infected with the HSV-1 virus early in life, they do not get their first cold sore until after puberty. Once someone is infected with HSV-1, the virus remains with them for the rest of their lives.
HSV-2 is much less common than HSV-1. It primarily causes genital herpes.
Cold sore infections are very contagious. The most common way for the virus to be transmitted is through infected saliva. You may pass on the virus through saliva regardless of the presence of sores. The contagion lessens as the blisters dry and gets crusted. Cold sores can never spread by using common surfaces like towels or clothes.
Cold sores often occur during a bout with the cold or flu virus. The cold and flu season is also the cold sore season. But you can get colds and flu in the summer - and cold sores too.
Injury to the target area is a common trigger that causes cold sores. Sunlight is excellent for your skin, but sunburn is not. Sunburn commonly triggers cold sores. Burning your lip with hot pizza, or biting it, or kissing someone with an active cold sore can cause cold sores too.
Any mental stress manifests itself physically, and is quite often responsible for causing cold sores. Some common "mental stress" triggers are upcoming events such as weddings, class reunions or presentations in front of people.
Cold sores are caused by the herpes simplex virus type 1, a highly contagious virus that, once contracted, will stay in your nervous system forever, occasionally rising from dormancy to make an appearance on your face. (Herpes type 1 is not to be confused with herpes type 2, of the genital variety). Because of this, once you've had cold sores you can't stop recurrences for good, but you can read the following suggestions to learn how to get rid of cold sores quickly, and how to avoid triggers and outbreaks of herpes type 1 as much as possible.
Cold sores are small but painful and even pus filled sores that affect the lips, mouth or nose of a person. Painful blisters, fever, irritability, and not to forget the hampering of one‚Äôs appearance are all associated with cold sores. Many people suffering from this problem often face the problem of reoccurring cold sores. This happens when the virus causing cold sores does not get completely eliminated from the body. Let‚Äôs first look at all the causes that can lead to cold sores.
The root cause of all cold sores is the herpes simplex virus and there are eight known types of herpes and two of these are commonly known for causing cold sores. Another common cause of cold sores is stress. This can be triggered by any event in your life which causes you to feel negatively and can have a huge impact on your skin. Cold sores can also occur when you have a cold or even the flu Many people are prone to get these right after a bout of the flu and they may linger as long as the flu if you aren‚Äôt careful to try and get rid of them. Sunlight is good for your skin in the right moderation, but sunburn is not.
