Hi . Being the victim of a road rage incident can be very traumatic in itself so you would probaly be pleaseed to know that the risk of conrtacting any disease from the unknown person is so negligible that you may ingore it. Infections transmitted through saliva that are of concern are HIV
, Hepatitis B
and C. The saliva has to contain some amount of blood however and should have have come in contact through a skin puncture or if the person bit or scratched you. Risk of infectious transmission through the eyes, mouth or nose is almost too minimal to be concerned about.
