A New York doctor who took the subway and went bowling in Brooklyn last night tested positive for Ebola today at New York's Bellevue hospital.

Dr. Craig Spencer, 33, was reportedly working with Doctors Without Borders in Guinea before flying back to the U.S. last week.

The New York Times reports that Wednesday night, Spencer took the subway from Manhattan to Brooklyn and spent time at an unidentified bowling alley.

It's unclear how he returned home to his Harlem apartment—according to reports, he took either a cab or Uber back. He was hospitalized at Bellevue Thursday after he developed a 103 degree fever and gastrointestinal problems. According to the Times:

Dr. Spencer began to feel sluggish on Tuesday but did not develop a fever until Thursday morning, he told the authorities. At 11 a.m., the doctor found that he had a 103-degree temperature and alerted the staff of Doctors Without Borders, according to the official.

A Bellevue employee told the Times that the medical staff had questioned why Spencer—who "seemed very sick,"—did not go to the hospital earlier.

Update 10 p.m.

Officials say Dr. Spencer took the A, L and 1 trains in the last week. Animal New York reports that a Bellevue doctor confirmed Spencer bowled at The Gutter in Williamsburg the night before he was hospitalized. The bowling alley has reportedly temporarily shut down operations.

He also reportedly went to the High Line and may have gone out to dinner nearby.

Health officials stressed in a press conference Thursday that it is extremely difficult to contract Ebola from a bowling ball.

Reports the New York Times:

If someone left blood, vomit or feces on a bowling ball, and the next person to touch it did not even notice, and then put his fingers into his eyes, nose or mouth, it might be possible. But, the Ebola virus does not not normally build up to high levels in saliva or mucus until very late in the disease — several days after the initial fever sets in — and it is unlikely that someone that ill would have just gone bowling. Also, the Ebola virus is fragile and susceptible to drying out. It does not normally survive for more than a few hours on a hard, dry surface.

Officials say Spencer didn't develop a fever until Thursday morning. Doctors say he left his keys behind in his apartment when he was hospitalized to keep people from entering accidentally.

Update 10:30 p.m.

Uber released a statement confirming Spencer used the service Wednesday night.

We reviewed our records and were able to confirm that one of our driver partners in New York provided a ride to the patient yesterday evening. We immediately contacted the CDC and NYC Department of Health and Mental Hygiene (NYC DOHMH), which stated that neither our driver partner nor any of his subsequent passengers are at risk. We have communicated this to the driver, and the NYC DOHMH medical team met with the driver in person, assuring him that he is not at risk. Our thoughts are with the patient and his loved ones.

Update 10:32 a.m. Health officials now say Spencer reported having a fever of 100.3-degrees Thursday morning, not 103; the initial confusion was due to a transcription error, according to the officials
