Hello and welcome to e health forum.
Viral infections resulting in sorethroat, sinusitis, and other conditions occur when individuals come in direct contact with individuals with either a active or latent infection.
Hence since you recently had a sexual relation, it is possible that you may be having a viral pharyngitis. It could also be a presentation of your stress and feeling of guilt. You can take âââAdvil or Motrin, to reduce your âsymptoms which may be very helpful. â
HIV is transmitted only by having multiple sexual encounters with a HIV positive person, and not with a single sexual ââââencounter. The risk of HIV transmission by a single sexual (anal) intercourse is about 0.08%, which is very less.
Since you did have intercourse with a HIV positive person, it would be in your best interest, to get tested for HIV. This can be done with a ELISA for HIV Antibodies and P24 antigen assay after 4 weeks from the last date of âââexposure.
This might give you a proper diagnosis and clear all your doubts.
