 [ Symptoms ] i was diagnosed with mononucleosis 7 months ago since then i have not been able to recover [ Disease ] well the symptoms of ebv commonly subside in 2 3 weeks but fatigue can last for 2 3 months and in very few cases can even last for about one year so the symptoms can be lingering from ebv infection only but i would also suggest you to get a blood culture done to rule out for any other infections a cbp +esr should also be done
