mt sinai hospital 2A local CBS affiliate in New York is reporting that the CDC has released the results of Ebola testing on a man who has been in isolation since Monday. The test results have come back negative. The patient is not believed to have Ebola, though his exact diagnosis is unclear. It is also being reported that he has shown improvement since Monday.

The original concerns emerged when a man came to the emergency room Sunday Night. He had recently returned from a trip to West Africa and was suffering from a high fever and gastrointestinal problems.

The Mt. Sinai Hospital officials confirmed the negative result earlier this afternoon. CBS New York reports:

The Mount Sinai Hospital patient who has been in isolation since Monday does not have the Ebola virus, hospital officials said Wednesday afternoon.

“We would like to report that the Centers for Disease Control and Prevention have determined that the patient kept in isolation since Monday, August 4, 2014 at The Mount Sinai Hospital has tested negative for Ebola Virus Disease (EVD),” the hospital said in a statement. “The patient is in stable condition,
is improving, and remains in the care of our physicians and nurses.”

It was not immediately clear what disease the man was suffering from. He had recently taken a trip to West Africa.

On Tuesday another potential case was reported in Ohio. Results of that test came back negative as well, less than two hours after the original story broke, signaling that the hospitalization and testing may have happened several days before the public became aware.

It is believed that at least 6 patients have now been tested nationally and that all tests have come back negative thus far, though the CDC has been slow to release any specific details of other cases.
