Swine influenza has been recognized as a respiratory disease in swine. Swine influenza viruses belong to the family Orthomyxoviridae, including three genera, Influenza A, B and C. All influenza viruses of significance in swine are type A, subtype H1N1, H1N2, or H3N2 viruses. Influenza A causes moderate to severe illness and affects all age groups of swine and produces a symptom like fever, lethargy, sneezing, coughing and breathing difficulty. The virus infects humans and other animals in addition to pigs. It targets and damages the lining of the respiratory tract, leading to swelling and inflammation. It has also major public health importance by causing numerous respiratory symptoms in both adults and children. Diagnosis of the disease is based on clinical symptoms while confirmation is done via laboratory tests using PCR (polymerase chain reaction) based kits. Antiviral treatment associated with either zanamivir alone or in a combination with rimantadine, Oseltamivir or amantadine is considerably important. Control of the virus can be achieved through vaccination, biosecurity measures, decontamination and dietary management. Therefore, appropriate prevention methods should be chosen and employed according to the specific regional context.
