Cold Sores Causes, Symptoms, Diagnosis and Treatment


What Are Cold Sores?

Cold sores are a viral disease caused by herpes simplex virus. They are fluid filled blisters which may develop around the lips.

Often developed in patches, once the blisters break, they are replaced by a crust. Cold sores usually take a few weeks to clear off and usually no treatment is required.

Cold sores are contagious and may spread via person to person contact. Since there is no cure for HSV infections, cold sores may recur.

However, antiviral medications may decrease the frequency of their occurrences and ensure that they heal at a faster rate.

Causes Of Cold Sores:

Cold sores are caused by type 1 of herpes simplex virus. HSV-2 causes genital herpes. However, both may cause sores to appear.

Being extremely contagious when oozing fluids, cold sores can also be transmitted if no visible sores appear. It can be transmitted via:

  • Sharing eating utensils with an infected person
  • Using razors and towels of an infected person
  • Kissing an infected individual
  • Oral sex with those infected by HSV

  • Viral infection or fever
