Full Text: The swine flu epidemic has reached our shores, and in his editorial (4) Barry Schoub brings us up to date on the background of this virus. The current outbreak of pandemic influenza (H1N1) 2009 demonstrates again how enigmatic, unpredictable and challenging the virus is. First isolated in 1933, it was one of the first human viruses to be isolated and has been studied intensively. However, it is unpredictable and has a penchant for upsetting prevailing dogmas.

As the virus frequently infects pigs, humans and birds it is not surprising that a novel swine influenza virus arose as a result of exchange of genetic material. Its spread has been non-seasonal and rapid, it affects mainly children and young adults, a higher percentage of patients require hospitalisation, it has a longer incubation period, and it has additional unusual clinical gastro-intestinal symptoms of diarrhoea and vomiting.
