Respected Sir/madam, Couple Of Days Back I Was Travelled On

Respected sir/madam,
Couple of days back I was travelled on train, where someone spitting through window, unfortunately I was sat on window seat, hence spitted saliva splash into my eyes directly. On that time i don't have water to clean up face and eye. Is this incident posses risk of HIV transmission? Perhaps if that salaiva contain tracable amount of blood, what's the risk of transmission of HIV? Am worried much about it. Please clarify my doubts and relive an anxiety.


Thank you.
