Tulsa, Okla. - With a 30-percent death rate, the MERS virus has been getting a lot of attention and rightfully so.
But how much do we need to worry about catching it?
Doctors say it's appears unlikely to spread here in the U.S., because it doesn't spread easily from human to human.
"There has not been a clear case of person-to-person transmission, outside of the healthcare setting yet, so I think we need to keep this in perspective," Dr. William Schaffner told NBC News.
MERS stands for Middle Eastern Respiratory System.
The flu-like disease started in the Middle East and is much more prevalent there, because it spreads relatively easily from contact with camels.
The only confirmed case in the U.S., a man in Indiana, is said to be recovering quickly.
