What are the chances i contracted oral herpes? - oral herpes more condition_symptoms

My friend and I shared us a drink because they do not want to pay. We are both free of herpes. Following a while, another person had been drinking from a cup without knowing me, and herpes. Instead of just a normal person, he decided to spit on him. I drank after he did not know he had been drinking. What are the chances that I now also herpes? How do I know if I do?
