Please note: I attempted to significantly improve this article, with the sole intent of removing (which I did) the {{ technical}} and {{ copyedit}} templates, but I am in no way a Biologist or Virologist, so I may very well have made factual errors. Please feel free to edit or revert anything that I contributed. Thank you! -- Iamunknown 23:51, 3 October 2006 (UTC) reply
