A possible case of Ebola has been identified at Howard University Hospital in D.C., according to multiple news reports Friday. The patient is reportedly being quarantined after presenting Ebola-like symptoms, but remains in stable condition, NBC Washington reported.

The possible case would be the second reported in the U.S. A Liberian man was diagnosed with the deadly disease in a Dallas hospital on Tuesday. Four other people who had contact with that patient have been quarantined, though none have shown symptoms.
