Despite their name, cold sores or fever blisters are not caused by common cold.
These annoying, itchy, painful, blistery lesions on your lips are a fact of life for many people around the globe.
In this post we will go through their symptoms, causes, and what can you do to prevent them from ruining your day.
What are the causes of cold sores?
Cold sores are caused by a very common virus called herpes simplex virus, or HSV.
There are two types of HSV that can cause fever blisters or cold sores: HSV type 1 and HSV type 2. Cold sores or herpes labialis are more commonly caused by HSV type 1.
Most people get their fist exposure to the virus in their early childhood through contact with family members or daycare children who carry the virus.
Bear in mind that there’s no definite cure that allows you to get rid of herpes simplex for good.
Once you get infected with it, it’s always there in your system.
It is thought that after the primary infection, the virus remains latent in our trigeminal ganglion.
Recurrence of an outbreak of the viral infection may happens as a result to exposure to bright sunlight, flu, and fatigue.
Here are the symptoms of cold sores
HSV type 1 infection usually causes a mild, self-limiting painful blistering around the mouth that is more commonly known as cold sores.
Cold sores or fever blisters can present themselves anywhere on the human body.
But they are most likely to appear on the outside of your mouth and lips.
Cold sores start with a tingling sensation, then burning sensation begins to surface.
Then finally the outbreak takes place as a painful red blister.
After a few days the blister breaks open oozing the fluid out and crusting takes place. A yellow crust keeps building up and falling off.
How Are Cold Sores Diagnosed?
To see if you have the herpes simplex virus (HSV) or not, your dentist or medical doctor will simply examine the cold sore or may take a swab from it.
Blood tests for HSV antibodies are also beneficial. A positive antibody result will indicate that you have the virus, even if it’s in it’s latent dormant form.
So who exactly gets cold sores?
Almost Everyone worldwide is at risk to get cold sores.
It’s important to note that Herpes simplex viruses are among the most common causes of human viral infections.
And men and women are both equally affected by HSV -1 infection.
It’s believed that the body’s immune response to HSV-1 and HSV-2 , persist for a lifetime, after the primary infection of the host.
As a result, a prevalence of Herpes simplex infections is measured by testing various populations for the presence of HSV antibodies.
It’s believed that 90% percent of all people experience at least one outbreak of cold sores in their lifetime.
Are cold sores contagious?
Cold sores usually last about 7 to 10 days and they are highly contagious until they dry up and crust over completely.You can get cold sores when you come into direct contact with people who are having an HSV type 1 outbreak. But it’s also possible to contract HSV from people who have the virus lying dormant in their bodies by sharing things that carry the virus.
