aio ab mono

I have a friend who was diagnosed w Mono less than a year ago. Today we were hanging out and they accidentally got spit on my telephone. I am worried I have any chances of contacting it. I disinfected my phone as well anything that could be considered contaminated. Is this enough? Will I get Mono? After my friend spat they rubbed it off with their hand but I fear I am going to get Mono. Please Help.
