What causes cold sores?
The HSV-1 and HSV-2 are the two forms of the herpes simplex virus, or HSV. HSV is the cause of cold sores and both forms of this virus causes herpes labialis, sores in the mouth and genital herpes, sores on the genitals.
Herpes simplex virus is introduced into the body through a break in the skin or orally. The virus can be transferred to other individuals when infected fluid goes into their bodies through touch or saliva like when using the same utensils, razors, kissing or touching. These are the common ways parents can infect their own child. The virus can enter through other areas in the body.
What are the symptoms?
Pain around or on your lips is the initial symptom of cold sores. Other common symptoms would be sore throat, inflammation of glands on the neck and sometimes other parts of the body, and fever. In children, drooling is an early sign of cold sores. The pain of cold sores can be intolerable for some people. Once the blisters break open, the healing begins when the clear fluid leaks out and the skin begins to crust on the area of the blister. It will completely heal after 1 or 2 weeks.
