La nostra amica inglese ci segnala una ricerca sulla mononucleosis che rileva che i giovani che hanno la mono sono piu' a rischio per la CFS.

Teens who develop "mono," otherwise known as infectious mononucleosis, may be at risk for chronic fatigue syndrome, according to a study published in Pediatrics.
Previous studies suggested that about 1 in 10 adults with acute infectious mononucleosis go on to develop chronic fatigue syndrome, according to the research of Dr. Ben Z. Katz, of Northwestern University Feinberg School of Medicine, Chicago, and colleagues.
However, what happens to teens with mononucleosis has not been studied as much. In this case, the researchers monitored 301 adolescents with the infection. Six months after the mononucleosis diagnosis, 24 percent had not made a full recovery.
Thirty-nine of these subjects were diagnosed with chronic fatigue syndrome, reflecting 13 percent of the original group of 301.
Six months later, at a 12-month follow-up visit, 7 percent had chronic fatigue syndrome, and at 24 months, chronic fatigue syndrome persisted in 4 percent. That is about 20 times higher than in the general teenage population.
All 13 patients who still had chronic fatigue syndrome at 24 months were female and, on average, they reported worse fatigue at 12 months.
Treatment with steroids for the infectious mononucleosis at the time of its diagnosis did not affect the risk of developing chronic fatigue syndrome.
