I heard a short interview with the opera houses intendant (if I recall correctly) and he was pretty ~~unphased~~ unfazed by this story. He said that it was not uncommon that a few of the 1400 guests of the opera house get nauseous during a show especially on hot days when air gets stale...
Sounded like he wasn't convinced the nausea during the Santa performance was because of the play itself.
