genital herpes is transmitted through naked, intimate contact with someone's genital area.
anytime someone is sick, they should never share food or drinks with others, especially not children nor should they kiss them. if she has a sore throat, regardless of the cause, she should not be engaging in these sharing activities.
Thanks for your comment, but it doesn't really answer my question. I am aware that genital herpes HSV-2 is a sexually transmitted virus. Now, if a person had given oral pleasure to the same person that had given he/she HSV-2, can it also be contracted in the mouth? If yes, can it be spread through saliva and/or sharing food or beverages...? My 3yo is a very spunky and free spirited little girl. There are times when my cousin is in the house and leaves food or beverages out on a table, and my 3yo will serve herself. I myself is aware that sharing while you're sick should be prohibited. My husband and I know that for ourselves, and don't engage in sharing activities or kissing with our children when we are ill. Now, in my cousins case, she's not one to really be very religious with things like that. Slips her mind I guess.
you can get hsv2 orally but it doesn't happen often. when it does, it rarely sheds so it's very unlikely you'd transmit it in general. oral herpes is typically transmitted through romantic type kisses. small children and infants are at a higher risk of contracting oral herpes from someone through less passionate kisses and potentially sharing drinks but the risk of that even is fairly small.
bottom line is - your cousin isn't any more of a risk to your children than any other adult they are around is. statistically 1 out of every 2-3 of the adults around them have hsv1 orally which sheds far more frequently and is far more of a potential issue than your cousin's situation would ever be.
