The virus does not remain on the skins surface for too long, once healing the sore probably contains no virus.
Most people with cold sores are very conscious of them and there's no sense touching them as it prolongs healing.
The virus is extremely unlikely to live off the skin in any quantities sufficient for infection fir anything more than a few seconds. It is virtually impossible to for infection to occur the way you suggest.
Thanks Fleetwood.
That's my concern only that as I can see her sore clearly, she dint even covered it with bandage or so.. that's why I am worried, if she touches her sore and touches plate or food too simultaneously. Then what is probability ? Any clear chances of transmission?
Please revert, because I have confusion
The virus can only practically be transferred with skin to skin contact. It is extremely unlikely to spread through an object such as a plate or food. If the person does not touch her cold sore, the there is no chance of transmission.
Over 60% of the population have the oral HSV1 virus including the chefs in every restaurant. Millions of meals every day and transmission does not occur.
