Legionella bacteria is spread when people inhale contaminated mist or vapor. It's rarely transmitted between people, but instead contracted from a person's environment (usually a building with a contaminated water system). The most recent, sweeping outbreak hit New York City in 2015 — and left 12 dead.
The two BAMC staffers work in an administrative building, not the center's hospital. Those working in the potentially contaminated building have been moved.
In a news release, BAMC said these dual cases qualify the spread to be considered an "outbreak."
