An author of a certain book enumerates different diseases that people can have:

eye disorders, sleep disroders, .... snoring, and the "new" diseases of Chronic Fatigue Syndrome and Fibromyalgia

Does it mean that according to the author these two diseases are "new" or that there are some "new" diseases that have something to do with Chronic Fatigue Disorder and Fibromyalgia?
These two diseases are "new".
OK, thank you.
