Hello
As you stated that girl was an
HIV infected and unfortunately died due to HIV infection .
You had sexual relation (once ) with that girl without condom or protection , call as unprotected sex.
Risk of HIV infection transmission depend on many factors :
The risk increases with sex from advanced-stage disease ( as may be in your case because you stated that girl died due to HIV infection means she was in advanced stage ),probably due to higher titers of HIV , presence of more virulent strains of virus.
Also depend of
viral load , if antiretroviral treatment taken or not.
Since every factors which are responsible for transmission for HIV infection were at risk in that girl and so also getting HIV infection by you more and more.
Anyhow, now get in rapid nucleic acid amplification test ( p24 pcr
rna ).
This test can be taken after 2 weeks of initial contract .
Hope this will help you.
