Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.
herpes type 1 virus is very common in 98% of all people in the USA
it is a very common virus to cause cold sores and fever blisters in the mouth.
have you had a cold sore before?
yes, I have looks at your blood tests.
IgG to HSV1 virus means you have teh virus in your body, but it is dormant and quiet
it is suppressed by your immune system and only comes out and causes cold sores and fever blisters as you get older if you don't get enough sleep or have a poor immune system.
