How long should you wait to kiss someone with glandjular fever?

Once you have the virus that causes mono you will technically have it for life, but that doesn't mean you are going to have to give up kissing. There are many opinions on when it is safe to kiss again after being diagnosed with mono ranging from 2-4 weeks all the way up to 18 months (yikes!). My doctor has told me that anyone I am kissing on a regular basis has probable been exposed already. I would say a good standard would be 2-4 weeks after your symptoms subside.
