Cold sores facts


Some exciting fact of Cold sores. These facts will be detailed in the main post

  • Cold sores represent blisters that usually develop near the mouth or on the lips.
  • They are caused by herpes virus strain HSV1 typically.
  • They usually heal between 7 and 10 days in the absence of any treatment.
  • It can be transmitted via direct contact since the virus is contagious.
  • If someone contracts the virus, it stays inactive for a while, but it can be activated by injury and fatigue


Cold sores are caused by the famous herpes virus (HSV). Both HSV1 and HSV2 are quite contagious and can be easily transmitted via close contact.

Immediately the virus accesses the body, it remains inactive, but a trigger can activate the virus and a sore development will follow.

Some people experience it once, while others experience it 2 or 3 times in a year.

Some do host the virus without experiencing any outbreak since it remains inactive.

Performing oral sex with someone whose genitals is infected by herpes could lead to HSV-2 infection.


A lot of people do have herpes virus without any symptoms. They can only tell if they are infected when Cold sores become visible.

Cold sores are usually severe when they initially show up since it’s a core infection.

Beyond that, Cold sores could be regarded as symptoms of HSV1 and 2. That is the only way you can know that the virus resides in that body.

In majority of cases, you can hardly notice any other symptom or sign of herpes infection.

The symptoms are harsher in young kids since their bodies lack the type of antibodies that can defend it against such an infection.

Symptoms may include:

  • blisters, lesions, or ulcers mouth surface or the tongue
  • tongue or mouth pain
  • difficulty in swallowing
  • lip swelling
  • sore throat
  • increased body temperature
  • swollen glands
  • nausea
  • dehydration
  • headaches

There could also be an infection of the gums and mouth, known as gingivostomatitis. This stays for up to 1 and 2 weeks, and it doesn’t recur.

Pharyngotonsillitis, is an infection of the tonsils and throat’, and it may occur when the primary infection affects adults.

The Stages

A Cold sore will certainly develop in various stages whenever it recurs.

  • That itching, burning or tingling sensation near the mouth could be a possible indication of an outbreak of cold-sore. This is immediately followed by sores that are filled with fluid. Swollen glands are equally possible.
  • The sores do appear in a similar spot. Cold sore is accompanied by irritation and pain.
  • Sores break as well as ooze.
  • It heals without leaving any scars behind because of the yellow crust that forms on the sores.

In most cases, after one or two weeks the Cold sores disappear.

The Diagnosis

Anyone who has experienced Cold sore before can easily recognize it when it is happening again.

Anyone who suspects an infection due to a sore that has lasted longer than necessary can see a health professional.

The symptoms are normally clear enough for any doctor to make a diagnosis, but they may equally need a blood test.

Occasionally, the doctor might need a fluid sample scrapped off from the surface of the Cold sore so he can detect the virus’ presence.

That is how it is done for patients whose immune systems are weak like those who are going through chemotherapy or those who have HIV or even AIDS.
