the bad breath could be a symptom of a fungal infection or it could mean its time to get your teeth cleaned.
you should discuss it with your wife none of your symptoms are of any std related illness,you should find out if she's having the same symptoms also track down your previous encounters just to find out about them .fever and sore throat likely mean something viral you could have gotten it from kissing or sharing a drink. your symptoms are pretty much right across the board for everything(west nile,cmv,mono,or just the flu).even dieabetis or household exposer to mold or dust.
I'd say gather all the info you can on you condition and weather or not its contagious and talk to your doctor.
check for hiv again if ur curious about it. None of what u say is hiv symptoms
Sorry I mean the Nights Sweats, Fever & sore throat is constant for 2 years...
I also need to add that I have recently developed bad breath, is this also a symptom?
