A patient kept in isolation at Mount Sinai Hospital in New York City for the past two days has tested negative for the Ebola virus.
The patient had been admitted to the hospital after arriving at the emergency room Monday with “a high fever and gastrointestinal symptoms,” according to a hospital statement.
The unidentified patient had been put into an isolation ward as a precaution since he had recently traveled to a West African country and had a fever.
According to the hospital, the patient was in stable condition and was continuing to improve.
The early symptoms of Ebola -- including fever, muscle weakness and headaches -- are similar to many other illnesses making it difficult for medical professionals to rule out the disease in early stages.
