Not about ME but 'chronic fatigue syndrome' gets a mention.

Human herpesviruses such as HHV-6 can remain dormant in cells for many years without being noticed. When reactivated, they can cause serious clinical conditions. Researchers from Würzburg have now found a way of differentiating between active and inactive viruses.

While HHV-6 was long believed to have no negative impact on human health, scientists today increasingly suspect the virus of causing various diseases such as multiple sclerosis or chronic fatigue syndrome.

MicroRnA molecules as markers
"Betaherpesviruses like human herpesvirus 6A, 6B and 7 integrate into subtelomeric ends of human chromosomes and acquire latency. This makes it difficult to recognize the early phase of viral activation [...]
"We have identified several viral microRNA molecules which are produced both during active infection and viral activation," Prusty explains. [...]Prusty is certain that the detection of these viral microRNAs can serve as an ideal biomarker under clinical conditions.
