The New Dundee Study of UK children with ME What do you make of the Dundee study finding evidence of infection in blood cells of children with ME/CFS in the UK? Has this sort of evidence been found before, or is this something really new? It’s positioned in the news as evidence ME/CFS is ‘real’ but what does it mean? Reply: We have also found that pediatric cases of CFS, just like adult CFS, show high prevalence of multiple bacterial and viral infections. I think that this is real, and it is important, and it shows that CFS like other chronic conditions is not just a mental problem but a medical problem.
