"Kiss of death"?

Can newborns only get "the kiss of death" virus if someone kissed them on the mouth? Did you let close family kiss your newborn baby? I'm 1 1/2 cm dilated and 70% thinned out so Its getting closer for him to make an arrival and I'm still freaking out about this whole kissing thing. My family don't listen very well, so I know they will kiss him even tho I don't want them too.
