// The overall age-adjusted EBV antibody prevalence declined from 72% in 2003–2004 to 65% in 2009–2010 (P = . 027). The prevalence in 2009–2010 by age group was as follows: 6–8 years, 50%; 9–11 years, 55%; 12–14 years, 59%; 15–17 years, 69%; and 18–19 years, 89%.18 Jul 2013//
however there is at least another site that says the antibody prevalence is 95%
EBV is a herpes virus DNA and may well show latency.
and boys and girls no really
the way to make latent viruses express themselves is - acridine yellow or fuse with sendai virus. - irradiate
and so later covid infection is a theory that will get up and run and has an experimental basis
thing is - - you should if it is re-expressed - actually find whole virus particles.
Latent virus infection ( of cell lines used in vaccines) was big business in the 70s and 80s - and mainly worked out. The obvious thing is that you should be able to recover the virus (EBV) and for long covid- - covid, and if you cant.... then it strikes me as an unlikely mechanism
