ARS symptoms usually occur within 2 to 4 weeks following initial infection, and very rarely occur 6 or more weeks after exposure.
These symptoms last 3 to 14 days and go away on their own.
Symptoms aren't reliable for diagnosis of HIV, only tests for HIV.

The cause of sore throat and fever, can be due to viral infections, such as flu or mononuclosis.
It could be caused by bacterial infection, strep throat, too.
