The Centers for Disease Control and Prevention (CDC) has offered additional guidance for clinicians who may suspect a patient is infected with a novel coronavirus that now is known as Middle East respiratory syndrome coronavirus (MERS-CoV).
The first human infections were reported in September 2012. As of June 7, the World Health Organization had received reports of 55 confirmed cases, including 31 deaths. All were linked directly or indirectly to 1 of 4 countries: Saudi Arabia, Qatar, Jordan, and the United Arab Emirates. No cases have yet been reported in the United States.
