Melting muscles: novel H1N1 influenza A associated rhabdomyolysis.

We report the first case of myositis and rhabdomyolysis after infection with novel influenza A (H1N1/09) virus. The case demonstrates the novel virus' capacity for causing significant disease. Myositis and the possibility of rhabdomyolysis should be considered in any individual presenting with influenza-like symptoms in which severe myalgia or muscle weakness is apparent. It is likely that we will see severe clinical manifestations of infection with this novel influenza virus in the coming respiratory virus season.
