AIDS infection route

[MINIDDD]

For adults, is HIV infection only through have unprotected (no condom) penetrative anal or vaginal sex, or Share IV drug equipment with other IV drug users？Can't any other behavior be infected with HIV?
In addition, I did four generations of p24 antigen test after 28 days. Can I completely eliminate the risk of infection？
Thank you for your help

Yes, your test is a 4th generation test and conclusive at 28 days and beyond.  You do not have hiv.

"No, but I read a lot of other people's posts." It is obvious if you read even a few posts that there are only 3, and since you have read many it shows that you are stuck in some kind of obsessive mindset that keeps you needing to be reminded of what you just read. For instance, you have asked the same question about what is a risk on this thread twice plus you wasted your time testing for something that was not a risk. Consider therapy because this is some kind of mental health issue.

You seem very familiar.  Have you already posted here?

No, but I read a lot of other people's posts
So apart from the two behaviors I mentioned above（have unprotected (no condom) penetrative anal or vaginal sex, or Share IV drug equipment with other IV drug users.）, any other behavior will definitely not be infected with HIV, right？
I can get on with my life, right

when people say the ONLY risks are . . . that means that yes, that's the only way and nothing else is a risk.  Yes, you can move on.

The answer to your first question is yes. You had no risk since you are asking about other methods. So it is time for you to move on instead of asking more questions.

If I have unprotected sex，Can I completely exclude infection by testing p24 antigen after 28 days？
