This is all fine and good, but:
-by 5 years old 1/2 of all people will have had mono
-and by 27 the percentage goes up to 90%
Sounds like life causes these conditions.
"In less-developed nations, 90 percent of people become infected by age 2.
Once infected, the virus remains in people for their entire lives."
Further in the report :
"Over the years, scientists have linked EBV to a few other rare conditions, including certain cancers of the lymphatic system.
Harley, who has devoted much of his career to studying lupus, found possible connections between lupus and EBV years ago.
That work includes proposing mechanisms that the immune system uses in response to the virus that lead to lupus,
and showing that children with lupus almost always are infected with EBV."(emphasis mine)
Since once someone has Epstein-Barr virus (EBV) and "it appears that components made by the virus interact with human DNA in the places where the genetic risk of disease is increased," Harley says.
"And not just for lupus, but all these other diseases, too."
My Hypothesis:
Therefore, is it possible that parents can pass on this DNA adjusted immune response onto their children also through family genetics ?
Since one of the transmission sources is exchange of saliva (ie.:"kissing disease"), this represents a communicable disease
with opportunity of new infections with family, friends, and physically intimate friends.
There is a reason why some genetic disorders are passed on in successive generations of a family,
and this study of the interaction of viri with DNA and immune system dynamics could well explain why certain diseases are passed on to succeeding generations.
