Abstract :
Influenza H1N1 infection is a viral infection with a seasonal preponderance, usually presents with flu-
like symptoms, and rarely has extra-respiratory manifestations. It has taken a pandemic form on few
occasions in the past. Involvement of the Central Nervous System (CNS), though rare, is described.
We describe a 42-year immunocompromised woman who presented with an acute febrile rapidly
progressive encephalopathic illness without the usual flu-like symptoms. Instead, she had widespread
Magnetic Resonance Imaging (MRI) brain changes resulting in a fatal outcome. Such an encephalitic
presentation of H1N1 infection without respiratory involvement has never been reported. J Microbiol
Infect Dis 2021; 11(3):166-169.
