Infectious Agents in Latvia

Researchers in Latvia studied 108 ME/CFS patients (94-Fukuda) and 90 “practically healthy” persons for eviAdvances-in-Virology-300x201dence of active infection with HHV-6, HHV-7 and parvovirus B19. 65% of the ME/CFS patients had evidence of one or more active infections with these three agents compared to 13% of the practically healthy subjects.  They conclude, “The association between occurrence of ME/CFS clinical symptoms, HHV-6, HHV-7 and B19 infection/coinfection reactivation and increased expression levels of TNF-α and IL-6 allows suggesting that these immunomodulating pathogens are involved in ME/CFS etiopathogenesis. Their role as trigger factors could not be excluded.” (Advances in Virology, Aug. 2012)
