The document discusses MERS (Middle East Respiratory Syndrome), a viral respiratory disease caused by a coronavirus. It was first described in 2012 in Saudi Arabia. MERS can be transmitted from camels to humans and between humans. Symptoms include fever, cough, and shortness of breath. While most cases have been in the Middle East, an outbreak in South Korea in 2015 was traced back to a single traveler from the region. Research is still needed to better understand MERS transmission and develop effective treatments.
