Middle East Respiratory Syndrome is here!
I'd be more concerned about the plane. MERS is not airborne, but can be transmitted through aerosols. Anyway, the United States and the UK are a whole lot better at containing these things than Saudi Arabia. What the CDC will likely do next is contact tracing - they'll track down everyone on the bus and those flights and ask them to report symptoms. It's relatively effective. Since MERS is mostly established in the Middle East (and apparently also transmissible between humans and camels), the virus probably has at least a three-day incubation period.On April 24, the patient traveled by plane from Riyadh, Saudi Arabia to London, England then from London to Chicago, Illinois. The patient then took a bus from Chicago to Indiana. On the 27th, the patient began to experience respiratory symptoms, including shortness of breath, coughing, and fever. The patient went to an emergency department in an Indiana hospital on April 28th and was admitted on that same day.
