The small blisters around the mouth and nostrils that define cold sores also known as fever blisters are due to a virus that, once contracted, stays with you, hiding until triggered.
Anyone can get a cold sore, and most people contract the virus through physical contact with an affected person. Even without a visible cold sore, a person can infect others via their saliva.
Researchers have found that more than half of Americans ages 14 to 49 carry the herpes simplex virus type 1 HSV —the virus that causes cold sores to develop—and up to 90 percent of Americans will have at least one cold sore during their lifetime. Kissing and intimate contact, as well as sharing food, drinks, and personal items e.
In one report in the journal Human Genome Variation, researchers suggested that a susceptibility gene is the main risk factor for cold sores.
However, the exact mechanism of such a gene is unknown. Once infected with herpes simplex, you will have the virus for the rest of your life. Recurrent cold sore outbreaks can be triggered by many different factors like stress, fatigue, hormonal changes including menstruationillnessdental work and even exposure to extreme weather. Many carriers of the herpes simplex virus never experience symptoms or an outbreak. When someone does experience a breakout, symptoms become apparent within a few days of exposure to the HSV virus.
After the first infection, the virus is dormant, hiding inside the nerve cells of the face, which means symptoms may not be experienced.
However, triggers can lead to recurrences of the virus. You can expect fewer severe symptoms with a recurrence, as the severity of outbreaks generally lessens over time. Children can develop cold sores inside the mouth, which are commonly mistaken for canker sores small lesions in the mouth. The doctor will be able to provide an accurate diagnosis based on a physical exam and other present symptoms. The initial infection of the herpes simplex virus is the most severe because the body has yet to build up its defenses to the virus.
High and persistent fever, problems swallowing, trouble breathing, or red, irritated eyes, especially in children, should be brought to the attention of a doctor. After initial symptoms develop, it can take two to four weeks to heal completely. During that time, cold sores go through three distinct stages. The symptoms and stages of an outbreak can vary depending on whether or not this is your first case or a recurrence. During the first stage of a cold sore outbreak—or the first one to two days, approximately—many people experience tingling, itching, or even soreness around the mouth.
Some people experience these sensations and never actually develop fluid-filled blisters. After a few days, small, hard, fluid-filled blisters begin to form on the lips, nose, cheeks, or other parts of the face.
Watch out for eye symptoms, such as sensitivity to light, pain, or grittiness in the eyes. You can also spread blisters to other locations on the body by touching sores and then another body part. If you touch a cold sore, wash your hands immediately.
The blisters may merge together and burst, resulting in small, open sores that ooze fluid. After a few days, the open sores will begin to dry out and scab.
Scabs can be very itchy and even crack, so avoid biting or picking at them, as this can worsen discomfort. Between five and 15 days after the initial outbreak, scabs will begin to fall off and affected areas will begin to heal.
Until cold sores have scabbed over, you can still infect others. Until then, be sure to avoid:. It is, therefore, important to remain vigilant and take steps to avoid infecting others with HSV. Cold sores cause pain, irritation, and even embarrassment. Fortunately, there are a number of ways to treat pain and symptoms to feel better faster.
If taken within 72 hours of an outbreak, certain oral antiviral medications prescribed by your doctor can help shorten the time it takes for cold sores to heal. For recurrences, be sure to talk to your doctor or dermatologist about prescription treatments. Your doctor may also recommend applying antiviral ointments directly to your cold sores.This author has been verfied for credibility and expertise. Cold sores -- those painful, fluid-filled, blister-like lesions that appear on or surrounding the lips -- are caused by the contagious herpes simplex virus, or HSV.
Two types of this virus, type 1 and type 2, can both cause cold sore-like lesions, but most cold sores are associated with type 1 infections 2. Cold sores often tend to recur during times of physical or emotional stress, although the exact triggers can vary among individuals.
Stress -- whether it's emotional stress, or physical stress, such as the stress caused by injury, surgery, or dental procedures -- can lead to depressed immune system function. The diminished immune response can trigger viral reactivation and a new outbreak. An article published in in the journal "Medical Hypothesis" concluded that the release of various chemicals during periods of both acute and chronic stress is at the root of immune system compromise in HSV sufferers.
During an acute illness such as the cold or flu, the body is using its full immune system armament. The defense system is fully engaged in an attempt to trap and kill the microbes causing the acute attack, and to heal the damage caused by these organisms.
All the while, the latent or hidden HSV that has been kept quiet by the surveillance of an alert and fully functioning immune system has a chance to re-emerge.
HSV then comes out of its sleeping phase, inducing the symptoms of itching or burning at the site where the blister-like lesion will develop. Within 24 to 48 hours a full-blown cold sore outbreak is in effect. The appearance of cold sores during the time of a fever has led to another commonly used name for cold sores: fever blisters.
Research published in in the journal "Cutis" measured HSV-1 cold sore outbreaks during the summer months. In this very large study population of 3, patients, roughly 10 percent were classified as having sun-induced flare-ups.
However, as the heat of the summer sun increased throughout the months of June, July and August, the sunlight-induced flare-ups increased too: the percentage of patients affected by sunlight ultimately increased to 40 percent.
The article speculated that solar UV exposure could induce recurrent cold sores either by lowering the immune system or by direct reactivation of the dormant virus.
