Swine influenza, a genetic reassortment of swine, avian, and human influenza viruses, is a respiratory disease of pigs that recently caused a pandemic. It contains deoxyribonucleic acid that is typical to avian, swine, and human viruses, including elements from European and Asian swine viruses. The main targets of the influenza virus are the columnar epithelial cells of the respiratory tract. The aim of this review was to present updates on influenza A viruses with particular attention to recent developments on swine flu H1N1. In-depth interest is on current historical accounts, pathogenesis, clinical features, diagnosis, treatment, and prevention. The review shows that there is tremendous improvement on the knowledge and understanding of the mechanisms of influenza disease and outcomes of management. There is an increasing diagnostic facility and emphasis on advanced infection control measures, encouraging frequent, adequate hand washing, use of alcohol-based hand sanitizers, and use of quarantine facility for treating serious cases and vaccination of people at risk.
