hello ,thank u for posting ur queries.
Since u had unprotected sex with partner who hiv
+ there 0.8 to 1%chance of being infected.
Symtoms of recent hiv infection is very non specific like u have described above,it can be like any other viral illness.
Since ur partner hiv + confirmed there is very high possibility that u may be infected and these symtoms may be due recent hiv infection.
I would suggest u to go for p24 level or western blot test as it is very early and hiv elisa
may come negative even u r infected.If western blot or p24 level come negative get it repeated after 6 weeks as it take time for antibody formation in our body.
If both the report come negative get hiv elisa done after 3 months.
if all the test are negative ,then there are less likely chance of hiv infection, it may be due some other viral infection which will be cleared in a week or 2.
hope information is useful.
