From the Wall Street Journal this evening:

A physician who had returned to New York City 10 days ago after treating Ebola patients in West Africa has tested positive for the disease, according to an official familiar with the findings.
Craig Spencer, a 33-year-old physician who worked with Doctors Without Borders and lives Upper Manhattan, is the fourth person to be diagnosed with the deadly disease in the U.S.
Dr. Spencer was diagnosed with the disease after treating patients in Guinea. He reported a fever and gastrointestinal problems Thursday morning and had quarantined himself in his Upper Manhattan apartment. He was rushed to Bellevue Hospital Center in an exposure suit, where he was quarantined in a specially designed hospital room.
… City officials said detectives were tracing Dr. Spencer’s contacts to determine whether anyone else is at risk of becoming ill. His girlfriend also was being tested for the disease. City officials said Dr. Spencer was communicative and cooperative about his whereabouts and contacts.
”Our understanding is very few people were in direct contact with him,” the mayor said. “The patient is in good shape and has gone into a great deal of detail. We have a lot to work with.”

Stay safe and healthy, New Yorkers.
