What is MERS?
MERS is a respiratory illness caused by a virus called MERS coronavirus, or MERS CoV. Symptoms can be very severe. One third of people with confirmed infections died from the disease. Most of those who died had underlying medical conditions, but the disease can affect anyone.
The disease originated near Saudi Arabia in 2012. Only two cases have been confirmed in the U.S., and both were travel related. The mode of transmission for the virus is unknown.
Report suspected cases of MERS immediately.
