What Increases Your Risk
People with
chronic fatigue syndrome (CFS) are generally 25 to 45
years of age. Women are more likely to have CFS.
CFS is rare in children. It may occur in teenagers, especially
young teenage girls. Unlike adults, teenagers are more likely to develop CFS
after having an illness such as
mononucleosis or
flu.
Studies show that about 4 people in 1,000 may have CFS—enough to
call it a major public health problem.4
