"chronic ebv" is redundant. EBV is ALWAYS chronic - as are all 8 members of the herpes virus family. The body never eliminates a herpes virus.
"Chronic EBV" is often used as short-speak for "chronically
activated EBV"
. Yes, all herpesviruses remain in your body for the rest of your life. For people with healthy immune systems, those viruses remain latent. The point with PWME is that many, or most, of us do
not have healthy immune systems and have chronically activated or frequently reactivated herpesviruses. That is a different situation from the usual latent infection healthy people have.
People with chronically activated or frequently reactivating herpesviral infections need antivirals. That's what antivirals are for. People knownto have reactivating herpesviral infections include transplant patients, HIV patients, and patients with immune dysfunctions such as PWME.
Extremely high antibody titres are
not common in adults many years past the original infection. Antibody titres drop over time. That's why the authorities are now recommending shingles (chickenpox) vaccine boosters for people over a certain age -- because over time antibodies can diminish to the point of not being able to protect from herpesviral reactivation. When instead of slowly diminishing, antibodies increase dramatically over time, that's reason to investigate further, especially if you have immune problems.
