Clinicians should maintain a high index of suspicion for this diagnosis in patients presenting with influenza-like symptoms that progress quickly 2 to 5 days to respiratory distress and extensive pulmonary involvement. The sensitivity of rapid diagnostic techniques in identifying infections with the pandemic 2009 H1N1v influenza strain is currently suboptimal. The most reliable real-time reverse transcriptase-polymerase chain reaction molecular testing is available in limited clinical settings. Despite 6 months of pandemic circulation most novel H1N1v pandemic strains remain susceptible to oseltamivir. Ensuring an appropriate oxygenation and ventilation strategy as well as prompt initiation of antiviral therapy is essential in management. Introduction As the novel swine-origin influenza A H1N1 v global pandemic is under way the medical community has already experienced an increase in hospitalizations from influenza-related complications in many geographic regions. Primary viral pneumonia is recognized as the most severe pulmonary manifestation of influenza. While uncommon during seasonal epidemics the syndrome has been well documented during the H2N2 pandemic of .
