Acute myelopathy associated with H1N1 virus infection

The swine-origin influenza A (H1N1) virus caused a pandemic infection in June 2009. The incidence of neurological complications due to H1N1 virus infection is unknown. Two cases of cervical acute myelopathy associated with H1N1 virus infection are reported. Both patients (male 29 years and female 24 years) suffered moderate to severe sensory and motor symptoms, but recovered completely within a few weeks. Acute myelopathy is a rare complication of H1N1 infection, but appears to be of similar course and prognosis as myelopathy associated with conventional viral infection.
