I don't think you should post in portuguese. Luckily for you, I'm brazilian! You don't have to worry about this episode, as HIV dies quickly when exposed to air.
I agree that this is not a risk. The only risks for HIV are unprotected vaginal or anal sex or sharing IV drug needles. A hug would not transmit anything. However, if you had unprotected sex with someone you are unsure of their status, then you yourself risked HIV. Is that what happened?
Your question was fully answered that you were neither at risk nor did you put anyone at risk (nor could you ever) from hugging them.
