The common cold is caused by 2 known coronaviruses and SARS by a 3rd. A previously unknown cornoavirus was discovered in an Amsterdam baby in 2003. Far milder than SARS and easily treated. Subsequently found by retrospective analysis of samples to have been infecting 7 other prior patients. http://www.genomenewsnetwork.org/articles/2004/03/22/new_virus.php Interestingly - discovered in January 2003 but only "news" now. -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
