My boyfriend has just been diagnosed with glandular fever? how likely is it that i am going to get it? we have been kissing for the last 4 months

Sorry....: You are very likely to get. If you had it before ,you may be able to fight it

You may catch it: If you haven't already met the Epstein-Barr virus, you're likely to become infected. But let's have our priorities straight -- kissing is worth the risk. I'm glad you have each other.

Hard to say: Many get this virus in childhood & will be immune. You have been exposed but may be immune & would never get it again. If he became contagious recently it can take a month or more for you to become symptomatic. I would not spend much time worrying since you cannot change what will happen either way.
