Swine flu: An overview.

ABSTRACT

Swine flu (swine influenza) is a respiratory disease caused by viruses (influenza viruses belonging to family Orthomyxoviridae) that infect the respiratory tract of pigs and result in nasal secretions, a barking-like cough, decreased appetite, and listless behaviour. Oseltamivir (Tamiflu) and zanamivir (Relenza) is the recommended drug both for prophylaxis and treatment. The best treatment for influenza infections in humans is prevention by vaccination.
