This condition, also known as “fever blisters” is presents with small fluid filled blister-like spots that appear in or around the outside of the mouth. These blisters are often grouped together in patches. After the blisters break, a scab forms that can last several days. Cold sores usually heal in two to three weeks without leaving a scar.

Cold sores spread from person to person by close contact, eg. kissing. They are usually caused by herpes simplex virus type 1 (HSV-1), and less commonly herpes simplex virus type 2 (HSV-2). Both virus types can affect the mouth or genitals and can be spread by oral sex. Cold sores are contagious even if you the sores are not visible. The virus usually manifests when the immune system has been compromised.

There is no cure for cold sores, but there are ways to treat the symptoms and prevent new outbreaks. For some strange reason, those under the Gemini star sign, are susceptible to this condition.
