I have a qiestion about HIV transmission. Yesterday I was talking to two people and they told me they are here in our school for N HiV conference. Then I asked them if they have hive then they looked at each other and said now they don’t have it and then they asked for a cigarette and I gave the guy 2 since there are 2 of them and he took them ( he might have touched me or scratched me i don’t really remember exactly, but if he did I would feel it) and they started asking me questions about hiv and how many people with hive back home in my country and I said they are close to less than.05%. Tgen I left them and went to my house on the bus and looked up the conference they are with on a website and it said all the people there are living with hiv! And that guy lied to me and said he doesn’t have it. My question is, am i at any risk of getting the hiv transmitted to me after what happened? Please answer my question because I am worried sick
