(CNN) – Centers for Disease Control and Prevention officials are packing up and getting ready to go to New York City, where a doctor who returned from Guinea ten days ago is showing Ebola symptoms.
In such situations, the CDC usually sends "disease detectives," CNN's senior medical correspondent Elizabeth Cohen reports.
The so-called detectives will follow up with people the suspected patient had contact with, see if anyone s getting sick, give instructions on how to monitor themselves, and quarantine them if needed.
