Middle east respiratory syndrome coronavirus: Update for clinicians

Although much recent focus has been on the recognition of Ebola virus disease among travelers from West Africa, cases of Middle East respiratory syndrome coronavirus (MERS-CoV), including travel-associated cases, continue to be reported. US clinicians need to be familiar with recommendations regarding when to suspect MERS-CoV, how to make a diagnosis, and what infection control measures need to be instituted when a case is suspected. Infection control is especially critical, given that most cases have been healthcare-associated. Two cases of MERS-CoV were identified in the United States in May 2014; because these cases were detected promptly and appropriate control measures were put in place quickly, no secondary cases occurred. This paper summarizes information that US clinicians need to know to prevent secondary cases of MERS-CoV from occurring in the United States.
