I had mono 20 yrs ago. I am now 61. I had Rheumatic fever as a child and have always tired easily. Within the past year, I have had several bouts of chill, fever, extreme fatigue, dizziness, abdominal cramping. Each episode would leave me without energy, extremely tired. I have just had complete bloodwork which stated testing shows that I have had a past infection with mono. I might also have a reactivated infection, but liver tests and other blood tests do not seem to confirm a reactivated infection. Suggestion is to treat this as mono for now. What does this mean for now , and is this contagious?
