Symptom #1: Not believing HIV can happen to you.
HIV does not have symptoms. The only way to know if you have HIV or not is to take an HIV test and the only way to avoid infection is using a condom. But there is something that increases the risk of getting HIV, and they're the “beliefs” that make us think that HIV can't happen to us, and that's where the risk of transmission lies. So if you "believe" you have one of the following symptoms, think again, because in that case, you could have HIV or be at risk of infection.
