What Is A Cold Sore/Fever Blister

 They are a small cluster of painful blisters 

It’s a virus that has been around for a long time, the medical term for it is simplex herpes virus one HSV-1. 

It’s a virus that attaches its self to your nerve endings.

It can only enter into the body via a break in the skin.

Future breakouts will be in the same area, or it could be a different cold sore and area altogether.

There is no known cure for the common cold sore, but there are treatments available that alleviate the pain and possibly help stop an outbreak occurring. Click here to take a look at our top remedies and reviews.

Spreading of the virus

How Many People Have Cold sores

The World Health Organization estimates that 3.7 billion people under the age of 50 have herpes simplex virus type 1 (HSV1) — that’s 67% of the world’s population in that age bracket.

Some people will carry the virus all of there lives it is just lying dormant within there immune system never to have an outbreak in there lives.

Some people are prone to regular episodes having them monthly during the menstrual cycle.

Others when their immune system is affected, i.e. cold or flu.

Its when the virus HSV-1 becomes active and causes a sore on your face nose or other areas.

So the actual cause of the outbreak is the virus but depends on the individual.

Where Do Cold Sores Come From?

Cold sores come from people spreading the virus while they have signs of the infection from the tingling or a physical blemish on them.

I have listed the various places you can contract the virus later in this publication.

Cold Sore Virus Spreading
Easiest way to spread the virus

Are cold sores contagious?

A Cold sore is very contagious the virus is spread around very quickly from everyday items like cutlery, Flannels cups anything that comes into contact with an affected area has the potential to spread the virus.

One of the leading health concerns is that if an infant contracts the virus, this can lead to severe complications.

 Avoid contact with babies and infants when you have cold sore symptoms.

One of the ways to control this is to use an invisible plaster such as compeed click here to take a look, or an alternative is Herpecilin invisible plasters click here. 

Can you get multiple cold sores

As mentioned above, the cold sore will only break out on the particular nerve ending and reoccur multiple times in that area sadly.

But the cold sore virus can find its way into different areas of the body and attach to different nerve endings. 

The way the simplex herpes virus one enters the body is via a crack in the protective skin layer.

The virus cannot reproduce itself once it has entered the body via the broken skin; it makes your cells create copies of itself which multiply very rapidly; this is the what appears the unsightly cold sore. 

Once the virus has peaked, and the cold sore has burst, the healing process can occur, but the virus hibernates now in the nerve waiting for its next chance to break out.

Multiple Cold Sores

Best hygiene practices.

As with any virus, COVID-19 has learnt us a thing or two about that hasn’t it.

It’s much the same with the herpes simplex virus.

Basic hygiene rules apply but just more directed at the infected area.

Because the virus is highly contractable, you need to take extra care not to touch the affected area, and other surfaces avoid kissing because it will spread to others.

 The simplex herpes virus does not multiply on its own; it survives on inanimate objects from a few hours to eight weeks.

I.e. hand cup toothbrush lips waiting for a piece of broken skin to come into contact with it.

Then it can enter the body then it tells the cells to duplicate thousands of times until you have a visible blister on the area.

 The virus survives on surfaces and objects longer in low humidity situations. 

When Are cold sore contagious

A Cold sore becomes Contagious as soon as the tingling sensation starts.

Medical research has shown that the peak of the contagious stage is when the blister has popped and is leaking serum thats the fluid which is under the skin.

Cold sore stages.

The first stage – is a tingling or burning sensation on or around the mouth; this indicates the start or a potential breakout.

It would be best if you were considering at this point using one of the recommended treatments, to help prevent or speed up the healing process.

The cold sore shouldn’t be present after 14 days if symptoms persist consult a doctor.

Is genital herpes the same

It could be transmitted to genitals or vice versa.

The genital strain is called HSV-2.

If body parts come in contact during the outbreak phase, it can very easily spread, so please avoid oral sex or kissing to help with stopping the spread.

Unless you know your partner doesn’t suffer from outbreaks while you have any signs of genital herpes or a cold sore.

Weak Immune system

What causes a cold sore outbreak

The medical term for the cold sore is (HSV-1). Herpes simplex virus one is the medical terms for the virus, its also known to some as a fever blister.

That is ultimately what causes cold sore is that virus; we are exposed to it at some point in our lives. Even from childhood, we can carry the virus until we are adults, and then we have a breakout.

For this article, various sources have been used from medical research studies and the NHS website. 

People with damaged or weak immune systems or undergoing cancer treatment, i.e. chemotherapy are at risk of complications.

Most certainly tell your GP during your consultation stages about a potential outbreak occurring because of the potential for it causes damage.

Especially if you are prone to them monthly outbreaks.

Dehydration – Can occur due in the elderly or vulnerable because they may have stopped drinking. As a result of the pain so it should be monitored.

The herpes simplex virus can readily spread to other parts of your body.

  Below is a list. 

  • Skin infections – can often occur if the virus comes into contact with broken skin.
  • Herpetic whitlow (whitlow finger) – this causes painful sores and blisters to appear on and around your fingers
  • Herpetic keratoconjunctivitis – this causes swelling and irritation (inflammation) of your eye area.
  • encephalitis – swelling of the brain ( Very Rare)

 If the virus gets into your eyes, it could cause blindness in extreme cases. To help limit the chances of this occurring, try to avoid your eyes.

If you wear contact lenses, wash your hands with antibacterial soap will help stop the virus spreading.

General cold sore information.

Cold sores are the vein of a lot of peoples lives; they are very contagious painful, unsightly and usually occurs on the lips or nose but if a part of the skin is broken anywhere on the body its potential site for cold sores. 

The cause of the outbreak is usually at the most inconvenient time when our immune system is already taking a hit you’re feeling unwell or a bit under the weather.

Medical research suggests that 77% of cold sores are caused by the herpes simplex virus one is know to live above the waste. While 33% is from herpes simplex virus, two know as herpes below the waste.

Cold sores occur and reoccur in the same area as the initial infection. This is to do do with nerve endings.

i.e. if a break out happened on the left nostril near the lip thats, where the break will happen again.

The virus could spread to other parts of the body; this is then an entirely new area unrelated to the original site.

That will have reoccurring episodes any broken skin has the potential to become a new location for the virus.

The simplex herpes virus lives under the skin down inside the nerve thats, where the cold sore hibernates. 

This is why they reoccur in the same place its the nerve cell associated with that cold sore virus.

Don’t be fooled by one cold sore that you will never get another because that’s wrong.

That particular cell fibre ending has gotten infected with the virus.

Contact with the current virus and any broken skin may cause multiple infection sites. 

Sadly for some, it’s a monthly thing with there menstrual cycle while others are asymptomatic and will never suffer but carry the virus all of there lives. 


As you can see, there is a high chance of contracting simplex herpes virus throughout your life from using simple silverware to a kiss.

3.7 billion people carrying the virus but a lot of people are asymptomatic.

One of the best and oldest remedies are still freely available to most just plain old simple ICE cube held onto the affected area will numb the pain for a short period.

The problem with medication for the virus is that it cannot be cured; you could take tables to help your immune system or creams, even light treatment.

But upon research into reviews and comments, there is no one sure-fire way of getting rid of them.

Some treatments work on some people and others it makes no difference at all, so the best thing to do is a bit of trial and error work to find out what works for you.
