Just wanted to update all, my son became ill with a flu like virus a year and a half ago. He was left with extreme fatigue and brain fog. No pain, he does work a full time job but never feels rested. We were originally told he had strep throat, then mono although both tests came out negative. He was testing high counts of EBV and then told he had chronic EBV. We continued to test his EBV antibodies every 6 month. His latest one tested negative for EBV, then we checked his blood again 2 weeks later and it came out negative again, not even for a past infection. This has been baffling, I would erge others to get rechecked. Clearly my son is not feeling good but we are no closer to figuring out why? Theses EBV antibodies were elevated from something else. Negative for Candida also. My son feels exactly the same, no better no worse.
