Swine influenza strain can be transmitted from human to human and causes normal symptoms of influenza. Transmission mainly occurs between pigs and pigs and humans. Our present study is of a 72yrs old male who died of H1N1 infection. Postmortem findings showed congested and edematous lungs with patchy areas of consolidation. Histopathological findings in lung revealed edema, pneumonic changes, hyaline membrane formation and focal cytophagocytosis.
