Post-infectious Fatigue Syndrome

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

Post-infectious Fatigue Syndrome (PIFS) is subtype of chronic fatigue syndrome defined by the Oxford criteria published in 1991.[1] According to the definition, post-infectious fatigue syndrome is chronic fatigue syndrome associated with or following a laboratory-confirmed infection.[1]

Criteria[edit | edit source]

The definition of post-infectious fatigue syndrome explicitly states that it is not known whether the infection has a role in causing the resulting chronic fatigue syndrome.[1]

Role of infection[edit | edit source]

The definition of post-infectious fatigue syndrome does not refer to any particular type of infection;[1] unlike postviral fatigue syndrome which limits the cause to viruses only.

A number of outbreaks of ME/CFS have been linked to viruses. Non-viral infections have caused a number of outbreaks.
