Someone I know says he was at both events over the weekend, and has been sick with a horrible stomach bug since Sunday night.  The most likely causes are food poisoning, norovirus, or salmonella. 

If anyone else has come down with diarrhea, vomiting, or bad stomach cramps, please post to this list.  It's important to know a) what you ate & drank at the events, and b) whether you used the SR bathroom during or since the events. 

If this turns out to look like norovirus going around, it will be necessary (as in, "not optional") to nuke the bathrooms ASAP with bleach (do not mix bleach with ammonia) on all surfaces including toilet seats, bowls, and flush handles, TP dispensers, sink and faucets and counters, wall switches and door knobs including areas around door knobs.  Norovirus is extremely contagious and persistent, transmissible from surface contact, and difficult to stop from spreading except by ferociously sanitizing all relevant surfaces.

If it's food poisoning or salmonella, that will become apparent from looking at commonalities in what people were eating.  Food poisoning and salmonella are not directly contagious, but would call for greater care about food sources & preparation methods to prevent another occurrence.
