Epstein-Barr is widespread - it sits latent in the human body, occasionally and opportunistically reactivating. It's detectable in 90% of humans, though most people don't have symptoms. According to functional medicine doctors I've talked to, it's a significant factor in a lot of what is understood to be long covid. I've had two reactivations in the past 3 years, each of which lasted ~6 weeks. The immune system does eventually get on top of it (assuming no other conditions keeping your immune system under siege) but while it's running rampant, you really are operating at just a fraction of your capabilities.
