The patient.info website has an article about the need to study the similarities between Long COVID and ME/CFS as the conditions have many overlaps.

A large number of people with long COVID are reporting similar symptoms to those who have myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Scientists are now researching the similarities between the two conditions. Many hope that exploring this interconnection will result in a better understanding of both long COVID and ME/CFS.
The flurry of research into the long COVID crisis is being seen by the ME/CFS community as a significant opportunity to dramatically advance our knowledge of ME/CFS. Despite the connection with viral infections, the exact cause remains unclear because it is possible that not all cases of ME/CFS are triggered by a virus.
Now, as lots of illuminating data continue to come out of long COVID research, new insights into both conditions could mean better treatments are found. This has the potential to benefit the millions of lives severely affected by ME/CFS every day.
