Airports take precautions against MERS after a traveler to Orlando was diagnosed with the syndrome.

If you travel through Miami International Airport, the Centers for Disease Control has posted health warnings at security check points. There are currently signs at the top of terminal E and D inside MIA. 

While you should remain alert, the CDC says the risk to regular travelers is still very low.  There are 500 confirmed cases of MERS in the world, but just 2 in the US.
