Why there is a misconception about angular cheilitis?

Many people mistakenly think that AC is contagious. They reason that it likes cold sores (oral herpes), or fever blisters. However, these are different conditions, and are in no way related to angular cheilitis.

Quick facts to remember about Candida

  • Candida can be detected in 93% of angular cheilitis lesions
  • Candida is also found in the mouths of about 40% of healthy individuals
  • Candida albicans is the most commonly isolated species of Candida
  • Candida species, usually Candida albicans, accounts for about 20% of cases

As stated above, candia exists even in healthy people. There are certain conditions needed in order to get angular cheilitis. Important ones are mentioned below:

Deficient immune system – A lowered immune system would allow the candida to increase in growth. This could happen for different reasons, like you would have to be ill enough for this to happen or have some nutritional deficiency that would lower your defenses.

Denture problems – If you have dentures than there is a possibility you could develop a form of it, but if you are healthy and are able to maintain the mouth area, than you can control it and never experience the problem.

Infection – Providing a wet environment is always a great way to get it, and even with a yeast infection, you would have to have an increase of the yeast infection such as thrush in order for it to begin to show up.

Closing note:

Candidiasis is a very common yeast (fungal) infection. The fungus normally lives in the body and it cannot be eliminated. Even if you try to eliminate, candidiasis can come back repeatedly.  Therefore the best way to avoid an outbreak of candidiasis is to strengthen your immune system. Though the disease angular cheilitis is not a contagious one, having a strong immune system will go a long way in avoiding possibility of getting infected with angular cheilitis.
