What Is A Cold Sore Or Fever Blister?

A cold sore, also called fever blister, is typically a small single blister or a cluster of blisters caused by a virus. This virus is called Herpes simplex labialis (Herpes simplex 1). This virus is not to be confused with Herpes simplex 2 which is a sexually transmitted infection. The viral infection is contagious and usually attacks the skin and the nervous system. It is common for the blister to appear on the lips, outer edges of the lips or on the nose. The tingling associated with the infection is as a result of the effect the virus has on the nerve endings.

How Is It Transmitted?

The virus enters the body through broken skin and is spread when an uninfected person kisses or comes into contact with the body fluid of an infected person. The virus can be left on the surfaces of items for example utensils and drinking vessels. This mode of transmission is important to prevent the infection and transmission of the viral infection. The virus remains dormant at the root of nerves and will become active periodically.

The Stages Of The Infection

  • The initial signal that something is wrong begins with a tingling on the lip or around the edges of the lip.
  • The fluid-filled blister or cluster of blisters then appears.
  • The area around the blister(s) often becomes red, swollen and painful.
  • The blisters break open and leak clear fluid.
  • A scab is formed after a few days.
  • The area heals up within a week, even without the use of medication.

    General symptoms

The common symptoms, in addition to the cold sore, are:

  • Fever
  • Sore throat
  • Headache
  • Muscle ache
  • Swollen lymph glands

Risk Factors

It has been recognized that there are some diseases and conditions which predispose patients to Cold Sores or fever blisters when the body’s immune system is suppressed. Here are a few:

  • Cancer
  • Stress (mental or physical)
  • Severe burns
  • Chemotherapy
  • Drugs used to suppress rejection in organ transplant


It is important to be aware of complications which could arise from the fever blisters and they include: widespread area of the skin being infected; transmission of the infection to the fingertips, eyes and involvement of other organs including the genitals.
These complications can occur in individuals with other illnesses which weaken the immune system. Undernourished persons are also at risk of having the aforementioned complications should they become infected.


doctorsStandard treatments include the use of anti-viral topical creams and oral tablets. Acyclovir is a popular generic drug and there are other improved related drugs which require 1-2 tablets twice daily dosage compared with 1-2 tablets five times daily.
A popular over the counter treatment is Docosamol (Abreva). Where there is swelling associated with the cold sore, a cortisone shot is given to reduce this.

Other treatments are the standard remedies for the relief of pain, fever and headache. Acetaminophen, paracetamol and other popular over the counter preparations are good choices.

It must be stressed that these anti-viral creams and tablets do not cure the body of the cold sore virus. They act effectively to shorten the course of the ‘flare-up’ or ‘break out’ and reduce the severity of the fever blister.


It is said that the cold sore virus is so prevalent that 4 out of every 5 persons have been exposed to the virus. For those who have never had an episode of fever blisters the following recommendations will reduce your risk of exposure to the virus:

  • Avoid kissing or having oral sex with a partner who has the fever blisters. The virus can infect the genitals.
  • Do not share toothbrush, eating utensils and drinking cups with individuals who have active fever blisters or are prone to break-outs.
  • Wash hands often especially after being out in public places.

For persons who already have the infection, you can prevent or reduce the recurrent flare-ups by practicing the recommendations above in addition to the following:

  • Change toothbrush after an episode of fever blister(s).
  • Avoid touching the infected lip and then other parts of your body such as the eyes and genitalia. Wash hands often.
  • Deal with stressors causing you to be stressed, unhappy or nervous.

A Special Note About Babies And Children

Oftentimes the blisters are missed in babies and children as they can appear just inside the mouth. They could be confused with ‘canker sores’.

The cold sore is the likely cause of the blister(s) especially if the care-giver has or recently had an infection.

Avoid the practice of family and friends kissing babies and children on the mouth. This must be firmly discouraged. The immune system is underdeveloped in children and this makes them vulnerable to infections.

Know Your Triggers

  • A compromised immune system: boost your health with supplements formulated for this purpose.
  • Trauma to the skin: this must be appropriately cleaned and dressed with and antiseptic or antibiotic preparation to promote quick healing.

Taking note of your trigger(s) will help you to act preemptively to reduce the frequency and severity of the breakouts.
