We have reported on an unexpected sudden out-of-hospital death caused by influenza A ⁄ H1N1 (2009) infection involving a young immunocompetent and previously healthy male. In our case, virological investigations were performed, including molecular analyses of common pulmonary and cardiotropic viruses in frozen cardiac samples, as well as genetic analysis of the influenza A ⁄ H1N1 (2009) virus for both hemagglutinin and neuraminidase genes. In our case, determination of viral loads in the absence of any inflammatory infiltrate in the myocardium has shown that influenza A ⁄ H1N1 (2009) virus can be a cause of out-of-hospital unexpected death in the young. Influenza A viral loads in respiratory samples collected from patients infected with pandemic H1N1, seasonal H1N1 and H3N2 viruses ./cache/cord-338331-27ic5zen.txt ./txt/cord-338331-27ic5zen.txt
