Middle Eastern Respiratory Syndrome Coronavirus (MERS CoV)
As of May 2, 2014, the CDC confirmed that the first case of Middle Eastern Respiratory Syndrome Coronavirus (MERS CoV) has been reported in a US citizen in Indiana. On May 11 a second case was confirmed in Florida. The cases are unrelated. Both were healthcare workers who had returned from the Middle East. On May 16, 2014 the first domestic secondary case was reported in Indiana. This case was exposed to the first case and remains asymptomatic, but lab testing indicates exposure and immune response to MERS-CoV. The CDPH and CDC have provided guidelines for healthcare providers.
