Thanks for your query at DoctorSpring.com
I understand your concern.
If you have blisters and if they break open the infected fluid comes out. You can spread the infection to the other parts of the body where there is a cut surface, injury or mucous membranes such as inside mouth if you touch them. If you don't have blisters you don't need to worry.
Patient replied :
So to clarify, I should only worry about spreading the virus to other parts of my body when I have an active sore? I can safely touch my lips and then other parts of my body or reuse a wet wash cloth right now without any real concern so long as I don't have a obvious sore?
