Burden of neurological cases linked to swine flu

In the two years ending February 2013, 25 neurological cases were identified ( 21 cases in children) of which 81% were influenza A H1N1 and 15% were influenza B.

The common presentations in children were encephalopathy, encephalitis, and one with meningoencephalitis; and in adults encephalopathy, encephalitis and one had Guillain-Barre syndrome.

The researchers noted none of the patients had been vaccinated, although eight had indications, and these patients had particularly poor outcomes with three deaths.
