Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
Herpes type 1 infection causes
cold sores over the lips and face and commonly involves the lips..
In case if a person has a history of cold sores he/she tend to transmit infection to other individuals by close contact like kissing and using things like glass, towels etc..
But in case if there is no cold sore present then the viral count seems to be very low over the skin of infected individual although it does not become zero..
But in this condition the individual is considered clean and chances for other person to get infected are less..
Moreover you can go for her blood investigation to rule out for viral count so that the exact status can be clear..
But in case if her skin is completely clear then you are at a lesser risk of getting infected..
She should also take a long course of
antiviral medications to prevent recurring episodes of outbreak of infection..
Hope this information helps..
Thanks and regards.
