Post-viral fatigue syndrome (PVFS) is a condition that presents a fatigue state resulting from a viral infection. The term is not widely used, but the state of prolonged or severe fatigue after illness is not uncommon. Some people experience fatigue and related symptoms for months or years following a severe viral infection.[1]
Classification
In the WHO's ICD-10, PVFS is a group header within 'other disorders of the brain', a neurological category. It is furthermore explicitly excluded from neurotic disorders. Listed under PVFS is benign myalgic encephalomyelitis.[2] Several alternative diagnoses to ME such as chronic fatigue syndrome (CFS) and neuromyasthenia are included in the alphabetic list of the ICD-10.
Post-viral fatigue syndromes may also include post-polio syndrome and multiple sclerosis.
Some researchers claim that post-viral fatigue syndrome is a biological state of weakness or activation of, or damage to the immune system,[3] and that it is common to many post-viral syndromes.
Risk factors
Viral infections that are suspected of causing post-viral fatigue syndromes are, among others, herpes simplex infections, including mononucleosis.
Research indicates that that the chance of developing a post-viral fatigue syndrome is more strongly related to the severity of the infection rather than to demographic, psychological or microbiological characteristics.[1]
See also
Forms of cancer have also been shown to be post-viral.[4]
Some non-viral diseases, such as Lyme disease, may lead to similar chronic symptoms.
