Swine flu is a respiratory disease caused by a new strain of influenza virus. The seasonal flu vaccines that are already available don’t protect against Swine Flu, so a new flu vaccine has been developed. For most people, swine flu is mild. It comes on quickly and generally lasts for around a week. It causes fever, tiredness, cough and sore throat. Other symptoms can include a headache, aching muscles, chills, sneezing, a runny nose, loss of appetite, vomiting and diarrhoea.
