The MERS case at a hospital in Orlando was declared "contained" Wednesday.

Two hospital workers who showed symptoms tested negative for the virus. Twenty other workers who were sent home have been closely monitored.

Officials said the disease poses little threat to the public now.

This was the second case of MERS in the U.S. The first was contained in Munster, Ind., last month.

Both patients brought MERS back after a trip to the Middle East. Now, the Centers for Disease Control is putting up signs in U.S. airports warning of the disease. The signs will appear at airports with many international flights.

The World Health Organization said MERS is not a global emergency -- yet. Since the disease doesn't spread easily between people, officials said it isn't a pandemic threat right now.

Still, it seems kill approximately one in four people infected. At this point, it's mainly showing up in Saudi Arabia.
