To the Editor: Since it first emerged in North America in mid-February 2009, the novel influenza A (H1N1) virus has spread to most other regions of the world, causing the World Health Organization (Geneva) to declare an emergent pandemic. H1N1 is a reassortant virus with six of its eight genes, including the hemagglutinin (HA) gene, originating from “North American triple reassortant” swine H1 viruses.
