What Causes a Herpes Cold Sore?
Herpes cold sores, also known as oral herpes or fever blisters, are caused by the herpes simplex virus type 1 (HSV-1). HSV-1 most often causes painful blisters around the mouth that crack open, ooze, and then scab over. Although HSV-1 is typically associated with oral herpes, it has been known to cause blisters on genitals (and other parts of the body) as well. Both oral and genital herpes are highly contagious and can be spread even if blisters are not present.
FAQ: Help with Herpes Cold Sores
Q. How did I get herpes?
HSV-1 is spread by contact with body fluids from an infected person. This includes contact with the actual blister, but can also be spread indirectly through sharing razors, eating utensils, or saliva. Children are often infected by parents who kiss them during an outbreak.
Q. How do I cure it?
Unfortunately, there is no cure for herpes cold sores. Once you’ve been infected, the virus remains in your body, but cold sore outbreaks will usually run their course in a few days to two weeks.
Q. Should I go to the doctor?
For cold sores from HSV-1, it is common for the blisters to clear up on their own. You can purchase topical creams to reduce the pain and inflammation, but if you have frequent or severe outbreaks, you should speak with a medical professional.
