Q: How are cold sores transmitted?

The herpes simplex virus (HSV) infection that causes cold sores can be spread by direct contact with cold sores or by exposure to an infected person’s saliva, such as by kissing or by sharing towels, drinking glasses, utensils, makeup, etc. [1] [2] Most infections occur after exposure to the saliva or sores of someone with an active, symptomatic infection, although asymptomatic transmission can occur. [2] People with active sores can also spread the virus to previously unaffected parts of the body, so handwashing is important during an active cold sore outbreak.
