No, because it has a reservoir someplace else as you mentioned. Note however that Ebola is not a major threat to mankind. Here is your worst case poster child, but note how it's not spread to large areas and killed a large fraction of the human population. The very traits that make it so dangerous when an outbreak does occur also make it difficult to spread itself over large areas. Here in Massachusett I'm far more likely to get killed in an automobile accident than to contract a case of Ebola. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
