I am much complimented and am willing to be of use wherever welcome, so please rattle my cage appropriately, but I protest that I am no medical man, decidedly no epidemiologist and no virologist. Also that I am a long way from the action, just like the Texans. Ummm... Well putting it that way... I'll go and browse a bit, but in a bunfight in this scale, I suspect it would be best if you directed me to points of major concern. Cheers, Jon.
