Hi,
Right i have to appolagise firstly for re submitting this post. Although i am thankful for the advice i do not think the question was understood. I said that there was blood in the saliva, not think how do i know because i saw it and it was horrible. So i am saying that when walking the saliva that this guy spat out had blood and i felt some hit my eye.
Is this a risk. There are no if's as i saw it.... Weird but true
and if not not a risk as i have been told does it not matter then how much blood is in the spit.
