You grandpa might not have been the initial "spredder" (lol) of the virus though, someone there might have been sick and come along anyway (as we all know people can be a little bit inconsiderate at times).

Elderly people and young children suffer more from viruses, so his symptoms might have come on quicker than others, who caught it at the same time he did.

It could've been in the food prepared by a sick chef, the bathrooms might have been contaminated, etc.

There are a thousand possibilities! (Unfortunately) [img]smileys/smilies_06.gif[/img]
