Hmm. The very first outbreak of Legionaire's disease was identified as something in the ventilation system of the hotel.
But what is not known is that those Legionaire's had a picnic with the cadets from the U.S.C.G. C. Eagle the same day in the open air. Nearly all of the cadets were debilitated, and and the ship was delayed in leaving port.
Maybe the cadets infected the Legionaires rather than the other way.
