Per the CDC: Middle East Respiratory Syndrome (MERS) is an illness caused by a virus (more specifically, a coronavirus) called Middle East Respiratory Syndrome Coronavirus (MERS-CoV). Most MERS patients developed severe respiratory illness with symptoms of fever, cough and shortness of breath. About 3 or 4 out of every 10 patients reported with MERS have died.
MERS in the U.S.
MERS represents a very low risk to the general public in this country. Only two patients in the U.S. have ever tested positive for MERS-CoV infection—both in May 2014—while more than 1,300 have tested negative.
CDC and other public health partners continue to closely monitor the MERS situation. We recognize the potential for MERS-CoV to spread further and cause more cases in the United States and globally.
