"At no point shall a dispatcher transmit over the radio any message containing the word 'Ebola' or related terminology."

That's according to an advisory sent to New York City 911 dispatchers, according to foxnews.com. So, what are they supposed to say instead of 'Ebola?' The code letters "F/T," as in Fever/Travel. That indicates that a 911 caller has a fever and has recently traveled to West Africa.

"Engine XXX, utilize Universal Precautions — you are responding to a Fever/Travel incident." That's what dispatchers must now say.

So, why the order? A source told FOX News it's meant to minimize fear over a citywide outbreak.

"Just like you can’t say bomb on an airplane, we can't say ‘Ebola,'" said the source. "Back in the '80s and '90s, taking universal precautions meant someone has AIDS. And we weren't allowed to say AIDS either."
