Pediatric myalgic encephalomyelitis/chronic fatigue syndrome

Pediatric myalgic encephalomyelitis and chronic fatigue syndrome (ME) and (CFS) has been defined by the Centers for Disease Control and Prevention (CDC) and the National Academy of Medicine (NAM) although it is usually diagnosed in adults. "Children below the age of 8 or 9 do not have the symptom pattern of adolescents past puberty. If the onset of the disease occurs during adolescence, the most common time of onset, the pattern is similar to that of adults." Children can be diagnosed at 3 months while adults are diagnosed at six months with the exception being symptoms that meet the International Consensus Criteria (ICC) for myalgic encephalomyelitis (ME) when a diagnosis should be made immediately for both children and adults.

It is especially important that parents, guardians, and educators understand ME/CFS's hallmark symptom, post-exertional malaise (PEM); symptoms will worsen 24-72 hours after physical or mental exertion. Cognitive dysfunction will impact their ability to do schoolwork even at home.

Recognizing that school nurses are necessary for helping children and their families navigate ME/CFS while balancing the child's education needs, the United States National Association of School Nurses (NASN) published School Nurses Can Improve the Lives of Students With Myalgic Encephalomyelitis/Chronic Fatigue Syndrome. The Chronic Fatigue Syndrome Advisory Committee (CFSAC), along with the US Department of Health and Human Services (HHS) published Supporting the Pediatric Needs of Educating Students.

Prevalence
A 2006 study by Jordan, et al, concluded that the overall prevalence rate for a community-based sample of adolescents (aged 13 to 17) was 181 per 100,000 or 0.181%. A 2011 study in the Netherlands reported a prevalence rate of 111 per 100 000 adolescents or 0.111%.

In 2012, the CDC estimated less than 20% of (adult) Americans that have chronic fatigue syndrome (CFS) were diagnosed. A 2008 ProHealth survey of 1,210 (adult) ME/CFS patients showed "29% had been ill from 6 to 20-plus years before being diagnosed."

Infectious onsets of ME/CFS
One in ten people who become infected with Epstein-Barr virus, Ross River Virus, or Coxiella burnetii will develop a set of symptoms that meet the criteria for ME/CFS; people with severe symptoms to these infections are more likely to develop ME/CFS. Genes are being considered for a risk in developing ME/CFS as sometimes several members of the same family will develop ME/CFS.

Other infections studied in relation to ME/CFS but not necessarily causative:
 * Bornaviruses
 * Candidiasis
 * Enterovirus
 * HHV-6
 * HIV
 * Hepatitus
 * Mycoplasma
 * Rubella

Other reported onsets:
 * Flu-like illness
 * Gastroenteritis
 * Influenza


 * Mononucleosis
 * Vaccines

Many outbreaks have been attributed to a flu-like illness including Incline Village, NV, Rockville, MD, and the Tapanui & West Otago, New Zealand Outbreak to name a few. For some unknown reason, young children are generally not impacted during an outbreak.

Generally accepted criteria for diagnosis

 * Canadian Consensus Criteria (CCC) A diagnosis of moderate and severe forms of ME/CFS are accurately made using this criterion. Adults can be diagnosed at six months while pediatric cases are diagnosed at three months.
 * International Consensus Criteria (ICC) - This criterion will accurately diagnose myalgic encephalomyelitis (ME). There is no requirement that the individual have symptoms for a specified period of time for diagnosis, as opposed to Fukuda and SEID, which both require 6 months in adults.
 * Systemic Exertion Intolerance Disease (SEID) - ME/CFS (SEID) is accurately diagnosed when the basic criteria are met. The Institute of Medicine report as a whole is a comprehensive review of the medical literature available at time of publication (2015). Adults can be diagnosed at six months while pediatric cases are diagnosed at three months.
