Between Oct. 17, when he arrived back in New York City from West Africa, and Oct. 23, when he tested positive for Ebola, Dr. Craig Spencer “did attempt to self-isolate,” officials said at a press conference Thursday.

“He was being mindful about contact with people,” said Dr. Mary Travis Bassett, the city’s health commissioner. “Our impression is that he spent most of his time inside his apartment.”

But not all of it.

Over that week, Spencer also rode three subway lines, took an Uber car, visited a park and attended a bowling party with friends. He wasn’t exhibiting symptoms at the time — except for fatigue — so it’s not likely he put anyone in danger, because Ebola can’t spread if symptoms aren’t present. But here’s a look at Dr. Spencer’s travels while he was carrying the virus:

1. Friday, Oct. 17

   Oct. 18 to Oct. 22

2. Spencer arrives at Kennedy International Airport. He had left Guinea, where he had treated Ebola patients, on Oct. 14, and traveled through Europe. It’s not known how he got home from the airport.

   At some point during this time, Spencer went on a three-mile jog, “a sign that he was feeling quite well,” Bassett said.

3. Spencer’s home is in Harlem. He took his temperature twice a day, and “was taking precautions on his own,” said Gov. Andrew Cuomo.

   Spencer started feeling “somewhat tired,” Bassett said.

4. Also at some point, Spencer rode the 1 subway line, shown in red. It’s not known where he went. Mayor Bill de Blasio has emphasized that even people riding in the same subway car could not have caught the Ebola virus because Spencer did not have symptoms.

5. Spencer “may have gone to a restaurant,” Bassett said, along the way to his next destination.

6. He visited the High Line in Manhattan, a park built above the streets on a section of an old elevated train line.

7. He took the A subway line (6a, shown in blue) and the L line (6b, shown in gray) as he went across the East River to Brooklyn.

8. Spencer attended a bowling party with friends at a vintage bowling alley called The Gutter in the Williamsburg section of Brooklyn. “He did bowl,” Bassett said.

9. At some point, Spencer got a ride in an Uber car. Initial reports said he took an Uber to the bowling alley, but Bassett said he took the subway; it’s possible he took the car home instead. Officials located the Uber driver and determined he was not at risk.

10. After coming down with a fever sometime between 10 a.m. and 11 a.m., Spencer was rushed to Bellevue Hospital in Manhattan, where he was put in isolation.

In total, officials determined that Spencer had been in close contact with his fiancée and two friends; they have been quarantined.
